+----------------------+
| The RGraph CHANGELOG |
+----------------------+
31st March 2013
===============
o [API] Added X axis drawing API object
o [API] Added Y axis drawing API object
o [API] *** The RGraph.getGutterSuggest function has been removed ***
o [API] Added the ObjectRegistry function RGraph.ObjectRegistry.Iterate() which can be used to iterate through all of the
objects in the ObjectRegistry. It takes an optional second argument of a comma separated string of chart types to
run the function for.
o [API] Added the ObjectRegistry function RGraph.ObjectRegistry.ClearbyType(type) - which clears the ObjectRegistr of the given
type of object.
p [API] Added the ObjectRegistry function RGraph.ObjectRegistry.List() which shows the object types that is held in the registry
o [API] Added the RGraph.sequentialIndexToGrouped(index, data) function which can make converting sequential indexes (eg the
coords array) to grouped arrays (eg the data in a stacked or grouped bar chart) easier.
[API] Added the function RGraph.sequentialIndexToGrouped(idx, data) - which takes a sequential index and returns an approprizte
group/index based on the data supply. It can be used to convert sequential indexes (such as those of the .coords array
into ones that you can use with the data arrays.
o [BAR] Fixed slightly wrong coords being stored in grouped bar charts (which use chart.hmargin.grouped)
o [BAR] Added a bevel effect option to the Bar chart: http://www.rgraph.net/demos/bar01.html
o [BAR] Added the demos/bar19.html demo - which shows a bar chart made up of the Rect, XAxis and YAxis drawing objects
o [BAR] The Bar chart now supports any number of Y labels.
o [BASIC] A new basic example of a vertical CSV has been added
o [CROSSHAIRS] Crosshairs can now wsnap to the nearest point with chart.crosshairs.snap
o [DEMOS] The gauge chart AJAX demo has been updated
o [DOCS] Added new 3D Pie chart HOWTO
o [DOCS] Added new Pie chart explode HOWTO
o [HBAR] The default chart.gutter.top setting has changed from 35 to 25.
o [MISC] Set methods can now be chained like this:
obj.Set('chart,gutter.left', 25)
.Set('chart.linewidth', 2)
.Set('chart.title', 'A chart!');
o [HBAR] The HBAR options chart.labels.colors and chart.xlabels.colors have been removed
o [LINE] The Line chart now supports any number of Y labels.
o [PIE] The default colors have been updated to gradients
o [RADAR] Added new properties: chart.labels.specific
chart.labels.count
chart.axes.bold
chart.axes.bold.zero
chart.axes.boxed
chart.axes.boxed.zero
o [MISC] The scale geration function has been rewritten. With scaled charts you can now have as many labels as you
wish - the name of the property in question will vary from chart to chart.
o [MISC] This has been optimised using loacl variable instead of globals:
http://www.rgraph.net/docs/updating-charts-dynamically.html
o [MISC] The text function has been rwritten. Coordinates for the text are now stored in obj.coordsText. So by using
the drawing API rect object you can place a "hotspot over the text and therefore make clickable text. This doesn't
work for angled text.
o [VPROGRESS] The defaults for the VProgress title have changed. spaecifically chart.title.vpos and chart.title.hpos have been
removed.
o [TOOLTIPS] The RGraph.HideTooltip() function can now take a canvas as an optional parameter (the same as what you get back
from document.getElementById()). If given the tooltip will only be hidden if the UIDs match (ie the tooltip
originates from that canvas).
o [WEBSITE] The forum has been updated. Email has now gone - to keep uptodate you will need to use RSS
o [ZOOM] The ZoomWindow and ZoomArea function have now been removed from RGraph altogether
IMPORTANT:
o [MISC] The text rendering function has been overhauled. Before you upgrade you MUST test your charts as this update affects
ALL chart types! As a result of this change there's lots of spurious comments in the files - so you are highly
recommended to minify and/or compress the files before use. This change is VERY significant so you MUST test
your charts!
31st January 2013
=================
o [API] The getObjectsByType() and getFirstObjectByType() ObjectRegistry methods have been updated. They now accept just
the desired type as the sole argument and return the applicable object(s).
o [BAR] chart.labels.colors and chart.ylabels.colors have been removed
o [CORNERGAUGE] Added title option
o [DRAWXAXIS] The RGraph.DrawXAxis() function now has four new properties:
o axis.noendtick.left
o axis.noendtick.right
o axis.noxaxis
o axis.scale.invert
o [DRAWYAXIS] The RGraph.DrawYAxis() function now has four new properties:
o axis.noendtick.top
o axis.noendtick.bottom
o axis.noyaxis
o axis.scale.invert
o [DRAWXAXIS] You can now use axis. and also chart. as a prefix for properties interchangably
o [DRAWYAXIS] You can now use axis. and also chart. as a prefix for properties interchangably
o [EFFECTS] The Bar chart Wave effect has been rewritten and sped up - most noticeably in Firefox. You will probably notice
speed differences in all browsers though. This speed up will be most apparent in effects but anything that
uses text will benefit.
o [GAUGE] Add chart.labels.specific so you can set your own labels
o [HBAR] Removed Firebug warnings
o [HBAR] Added chart.noaxes and
o [LINE] Added the Trace2 effect which achieves the same effect as the Trace effect but using a different method
o [METER] Added chart.angles.start and chart.angles.end - please check your charts are as they should be
o [MISC] The Radar, RScatter and Rose chart background grids have been updated so that they line up with tickmarks. See the new
look here: http://dev.rgraph.net/tests/2013-01-13/circular-chart-sticks.html
o [API] Added pseudo-constants for easier browser checking: ISIE ISIE6 ISIE7 ISIE8 ISIE9 ISIE9UP ISIE10 ISIE10UP ISOLD So you could
do this: if (ISIE9UP) { ... }
o [RADAR] chart.background.circles.spacing has been removed
o [ROSE] Added chart.background.grid.spokes.overhang which defaults to 0, so now there is no overhang
o [ROSE] Fixed spokes being drawn out of alignment by 90 degrees
o [SCATTER] The Scatter chart custom tick function is now passed the dataset index as well as the data index as arguments;
See here for details: http://www.rgraph.net/docs/scatter.html#custom.tickmarks
31st December 2012
==================
o [ANIMATIONS] The rotateIn animation now rotates in from the left (10px)
o [API] The DrawXAxis() and DrawYAxis() functions now support an axis.linewidth option
o [DOCS] Added range inputs (sliders) to the 3D example. For best results use Chrome or Safari to view the page:
http://www.rgraph.net/docs/howto-3d-effect.html
o [DOCS] Added a Contract/Expand HOWTO: http://www.rgraph.net/docs/howto-make-a-contract-expand-transition.html
o [EFFECTS] Added the Contract effect - the opposite of the Expand effect
o [HPROGRESS] Added chart.bevel
o [EFFECTS] You can now turn the bounce effect off in the Expand() effect
o [LINE] The chart.backdrop option now supports splines
o [LINE] The way that the Y coordinates for lines has changed significantly. There shouldn't be any visible changes.
o [MISC] The minify PHP script has been removed - the jsmin C program should be used instead.
o [MISC] Automated all docs pages for charts
o [RADAR] The default for chart.axes.color has changed from black to rgba(0,0,0,0)
o [RADAR] The default for chart.background.circles.poly has changed to true
o [RADAR] The Radar chart now has a Trace effect
o [ROSE] Added ability to set the density and the color of the background concentric circles
o [VPROGRESS] Added chart.bevel
30th November 2012
==================
o [API] The DrawAxes() function has been renamed to DrawYAxis() and a DrawXAxis() function has been added.
o [API] The RGraph.Reset() method has been updated so that it now removes all relevant objects from the ObjectRegistry. You may find
it easier to use and more clear then manually clearing the ObjectRegistry. In many cases you can just replace your .Clear()
call with a .Reset() call. Note that any translation that has been performed will be lost as well. If you want the old Reset
method it's very easy to make one (or use this):
function myReset (canvas)
{
canvas.width = canvas.width;
}
o [BAR LINE SCATTER] When you use a background image - the background image will set a property
(obj.__rgraph_background_image_loaded__) when the image has loaded.
o [EFFECTS] The Expand effect now has a small bounce effect. It also takes less time to run.
o [EFFECTS] Added a new CSS animations library. Recent browsers support these (eg IE10+, Chrome, Firefox, Opera, Safari)
o [HOWTOS] The VProgress/Bar HOWTO doc now redraws the X axis when all of the vprogress bars have been drawn
o [HPROGRESS] The default for chart.tickmarks.zerostart has changed to true
o [LINE] Fixed bug with filled line chart tickmarks (the end* variants)
o [LICENSE] The non-commercial license has been formalised as the Creative Commons Attribution NonCommercial license
o [MISC] The method of antialiasing has changed. Instead of a function that rounds to the nearest
half-pixel - the canvas is translated by half a pixel and then values are rounded.
o [RADAR] The default for chart.labels.boxed has changed from true to false
o [VPROGRESS] The default for chart.tickmarks.zerostart has changed to true
o [MISC] The way the multiline angled text is rendered has changed - you may need to change your labels if you're
using multi-line angled labels. If you need large labels you could also consider using a key, switching
from the Bar chart to the Hbar chart or using tooltips to display the extra information.
31st October 2012
=================
o [MISC] Stable release
o [RADAR] The horizontal alignment of the Radar chart labels has been adjusted. Labels look better - particularly when not boxed.
27th October 2012
=================
o [EVENTS] Events have been moved back to DOM2 but with a key difference. Now the events are installed once only - similar
to how the DOM1 events were. As a consequence the RGraph.ClearEventListeners has been re-implemented so that you
can clear the window or the canvas event listeners.
o [FUNNEL] The Funnel chart has been converted to new style Hit testing which is faster, more accurate and far less
complicated - though the difference in speed is unlikely to be norticeable.
o [HBAR] The HBar settings chart.vmargin and chart.vmargin.grouped for grouped HBars have been updated to act the same as the Bar chart.
The chart.vmargin setting is used to seperate the groups of bars whilst the chart.vmargin.grouped setting is used to seperate
individual bars within the group.
o [KEY] The position of the key in gutter mode has been updated - it's now centered regardless of the gutter settings
o [MISC] As an example of the faster and more accurate click-testing that is planned for the November stable release, the Marker1
object and Funnel chart have already been converted. So now, in the case of the Marker1 object, not only can you click
on the circular part - but also the curvy pointer part too. You can see an example here:
http://www.rgraph.net/docs/drawing-api-intro.html
o [MISC] The API functions RGraph.LinearGradient() and RGraph.RadialGradient() can now take more than two colours if you wish to
specify them.
o [ODO] The chart.green.solid, chart.yellow.solid and chart.red.solid options have been removed.
o [RADAR] Added chart.labels.background.fill and chart.labels.boxed
o [THERMOMETER] Now ALL of the "mercury" in the Thermometer is clickable and highlighted. See this page:
http://www.rgraph.net/examples/thermometer.html for a demonstration
16th October 2012
=================
o [MISC] Certain tooltips are now placed above the bar. Or below in the case of negative values on the Bar chart.
o [MISC] Added support for easy events specification for charts that support chart.events.click and chart.events.mousemove:
myChart.$1.onclick = function (e, shape)
{
// Handle the click event
}
myChart.$1.onmousemove = function (e, shape)
{
// Handle the mousemove event, eg:
e.target.style.cursor = 'pointer';
}
Also added basic examples of this for the Bar/Line/Pie chart and a HOWTO doc
o [MISC] Added support for "dollar" specification of events. So if you just want to add an event
listener to the third bar you can do this:
bar.$2.onclick = function (e, shape)
{
// Put your code here...
}
It's $2 because it is zero-indexed (ie the counting starts at zero). There are a few basic examples of
them being used here: http://www.rgraph.net/docs/basic-index.html
o [MISC] Added support for easy and simple gradients: Gradient(white:red)
o [MISC] Tooltips are now placed above the relevant bar (bar related chart tpes).
o [CORE] The RGraph.getMouseXY(e) function will now accommodate borders and padding on the canvas
o [LINE] The interactive key will now work when the key is placed outside of the chart area
5th October 2012
================
o [GANTT] IMPORTANT: How you specify the Gantt chart events has changed. Instead of using the chart.events property the events are
now given as the second argument to the constructor. The array is the same format. The constructor of the
Gantt chart now looks something like this:
var myGantt = new RGraph.Gantt('cvs', [
[0,15, null, 'Richard', '#afa'],
[31, 28, null, 'Gerry', '#afa'],
[0, 31, null, 'Tom', '#afa']
]);
o [HPROGRESS] Now when the cusor is over the whole chart area (including the background), charts "behind" the progress bar do not
fire their events
o [VPROGRESS] Now when the cusor is over the whole chart area (including the background), charts "behind" the progress bar do not
fire their events
o [THERMOMETER] Now when the cusor is over the whole chart area (including the background), charts "behind" the progress bar do not
fire their events

{
}
This is the same as setting the properties, though may be to your taste more.

on a canvas to get the relevant object.
o [BIPOLAR] Added a .getValue method(). This allows you to click on the chart and get the relevant value.
o [GAUGE] Added .getValue method. This allows you to click on the chart and get the relevant value.
o [GAUGE] Added new properties: chart.centerx, chart.centery and chart.radius. There's an example here that shows
three animated interactive (by way of the .getValue method) Gauges on the same canvas achieved using
the new ObjectRegistry:
http://dev.rgraph.net/tests/2012-03-25/center_gauge.html
o [GAUGE] Added the option chart.border.graduated, which defaults to true.
o [LINE] When chart.tooltips.hotspot.xonly is in use tooltips now appear next to the point
o [METER] How the Meter chart works out the centerpoint has changed. Now you shouldn't get Meter charts that are
too big for the canvas. Also, if you want to, you can spcify these to control the size and position of
the Meter:
o chart.centerx
o chart.centery
o chart.radius
o [ODO] How the Odometer works out the centerx and centery has changed. Though can override these if you wish with:
o chart.centerx
o chart.centery
o chart.radius
o [PIE] The Pie chart now prmarily uses the gutters to calculate the center X/Y position, though you still
stipulate them with chart.centerx, chart.centery and chart.radius if you wish.
o [PIE] The Pie chart now has Shrink effect to complement the Grow effect
o [RADAR] The way the centerx/centery is calculated is now based on the gutters. You can also override them with:
o chart.centerx
o chart.centery
o chart.radius
o [ROSE] The way the centerx/centery is calculated is now based on the gutters. You can also override them with:
o chart.centerx
o chart.centery
o chart.radius
o [THERMOMETER] Added Grow effect
o [WEBSITE] Going forward, the website will be based on the stable version of RGraph.
It's currently based on a beta version.
3rd February 2012
=================
o [DOCS] Updated the combining charts page
o [MISC] Added a tool to make working with separate gutters easier
o [MISC] Added a tool to ease converting images to data: URLs Using data: for static images URLs can help improve the performance
your website
o [MISC] Background images are now achieved by placing an image tag behind the canvas - instead of painting the image onto the canvas.
This increases performance and reduces flicker in effects.
o [PIE] chart.strokestyle can now be an array of colors as well as a string
o [PIE] The Pie chart is now positioned by using the gutters (first and foremost). The chart.align property is no longer used.
o [SCATTER] Added __index2__ to the Scatter chart
o [WEBSITE] Updated the front page chart to a Pie/Line combination
28th January 2012
=================
o [GAUGE] You can now show the value as a text label with chart.value.text
o [GAUGE] You can now have medium sized tickmarks with chart.tickmarks.medium
o [MODALDALOG] When the .Hide or .Close methods are called, the ModalDialog is now removed from the DOM instead of just being hidden
o [MODALDALOG] The ModalDialog is now created from scratch every time it is shown
o [MODALDALOG] The ModalDialog can now be given as a string, like this: ModalDialog.Show('string:My Dialog
')
o [HOTSPOTS] The way that hotspots are handled has changed. eg For tooltip highlighting, the hotspot is calculated
using coordinates, and then the relevant area is covered with a semi opaque DIV. This is instead of
drawing on the canvas itself. Doing so increases performance (far fewer redraws are needed) and also,
more importantly, means it is much easier to incorporate multiple charts on one canvas. So far the
following charts have been changed:
o Thermometer
o [MISC] chart.highlight.stroke is now deprectaed
o [MISC] All chart types have now been converted to the new object registry. This means that you can mix and match different
chart types on the same canvas and still have dynamic features. This involved:
o Objects now have a UID created in their constructors
o Objects no longer clear event listeners when the .Draw() method is called
o Objects are now ALWAYS registered for redrawing
o The majority of charts use common mehods to install tooltiip event listeners ( RGraph.AllowTooltips() )
o Each object has it's own .Highlight() method for highlighting the chart.
o The .getShape methods now return textual array keys as well as numeric ones
o There is a new ObjectRegistry in RGraph. Objects are always registered with it in their constructors.
The objects are then redrawn by calling the RGraph.Redraw() method.
o [THERMOMETER] Added tooltips
13th January 2012 (STABLE)
=================
o [DOCS] Added HOWTO for making a transition effect
o [GAUGE] The positioning of the titls has been tweaked slightly. You can now also override the positioning completely
with chart.title.top.pos and chart.title.bottom.pos. These are decimals (which are null by default) and are
multiplied with the radius to get the exact position.
o [VPROGRESS} Properties to individually control the side title have been added:
o chart.title.side.bold
o chart.title.side.font
o chart.title.side.size
o chart.title.side.color
[WEBSITE] Added RSS feed for releases

o [MISC] Fixed "conflict" with user events and tooltips
o [MODALDIALOG] The ModalDialog has been altered so that it is ALWAYS (re)created when it is shown - ie it is no
longer cached once it has been created

o [GAUGE] Added chart.title.y
o [MISC] The test area is undergoing a revamp - if you would like me to add your chart to it please email it to
me at the support address. Keep in mind that the chart should be self-contained, and that the actual data
is largely irrelevant (so replace sensitive data with junk data). Keep in mind that the test area is not private.
o [MISC] The two scale properties chart.scale.point and chart.scale.thousand have been synchronised across all chart libraries.
18th December 2011
==================

o [DOCS] The dynamic example (http://www.rgraph.net/docs/dynamic.html) scroll speed has been slowed down. This was
done by simply increasing the number of data points shown from 100 to 250.
o [EFFECTS] Added an opposite effect of Reveal - Conceal. These two effects can be combined to make a transition effect.
o [LINE] Added new background images properties:
o chart.background.image.stretch
o chart.background.image.x
o chart.background.image.y
o chart.background.image.align
o [MISC] The getValue() methods can either take an event object as its argument or a two element array
of the coordinates to return the value for.

26th November 2011 (STABLE)
==================
o [ADJUSTING] The Rose chart adjusting has been removed
o [DOCS] Added an example of financial data represented using the Scatter chart:
http://www.rgraph.net/docs/financial.html
o [DOCS] Added an example of getting data from an XML file on the server
o [EFFECTS] The slide in and slideout have each had the argument used to stipulate the direction renamed:
RGraph.Effects.jQuery.Slide.In(obj, {'from': 'right'});
RGraph.Effects.jQuery.Slide.Out(obj, {'to': left'});
o [LED] Added more punctuation characters
o [SCATTER] chart.boxplot.width is now a SCALE value, not a PIXEL value. Therefore, if your chart.xmax value is 28 (for four
weeks say) 1 week would be represented by a value of 7, whereas before that would simply be 7 pixels.
17th November 2011
==================
o [KEY] Separated out the key functionality into its own file - RGraph.common.key.js. If you use the key you will need to
include this file. If you dn't use the key this will save roughly 30k.
o [MISC] The charts libraries have a new technique that avoids you getting blurry lines that appear to be thicker than a
single pixel. This roughly affects roughly 12 of the charts libraries.
o [ZOOM] Added chart.zoom.mode.thumbnail.fixed that fixes the thumbnail zoom window in the top left of the canvas
12th November 2011
==================
o [DOCS] Added paragraph to miscellaneous docs regarding log scales.
o [DONUT] The Donut chart is now done correctly instead of being a big white hole in the center of the Pie. If you use the
Donut - check your charts, particularly if you use a coloured center as it is no longer coloured. If desired
though, you can still get a coloured center by utilising the ondraw custom event to draw a big white circle
that's half the radius in size. The shadow will now work correctly. For an example see here:
http://www.rgraph.net/examples/donut.html
o [GAUGE] Added four new peoperties for controlling the colors: chart.border.inner
chart.border.outer
chart.centerpin.color
chart.needle.color
o [LINE] When tooltips are triggered by the mouse X position only, the cursor will now only change if it's actually
over the point.
o [MISC] IE7 is now supported with ExCanvas
o [MISC] The latest stable Chrome (released on 10th November 2011 appears to be back up to speed when using the
requestAnimationFrame() function - as such the Pie chart animation on the front page has been improved.
o [PIE] There is now a Pie chart Wave effect
o [PIE] IMPORTANT: The Pie chart .getSegment(e) method now returns angles measured in radians, not in degrees. Roughly, 1 radian = 57.29
degrees (or 180/Math.PI ).
o [ROSE] IMPORTANT: The Rose chart .getSegment(e) method now returns angles measured in radians, not in degrees. Roughly, 1 radian = 57.29
degrees (or 180/Math.PI ).
o [WEBSITE] There's now an example of the Pie chart RoundRobin and Implode effect on the front page of the website
4th November 2011
=================
o [BAR] Added the Bar chart Wave animation. It's smoothest in MSIE9+ and FF7+
o [FUEL] Rewrote the Fuel chart Grow animation. It now "Grows" from the last position - not zero all the time. NB To get
rid of the flicker when using the Grow animation you must set chart.icon to null

o [HPROGRESS] Added the HProgress Grow animation
o [LINE] Lines are now restroked (if they're filled and accumulative)
o [VPROGRESS] Added the VProgress Grow effect
27th October 2011
================
o [BAR] The bar now has support for chart.colors.sequential with grouped and stacked charts

canvas based animations.
o [ROSE] The Rose chart Grow frame rate is now set at 60 frames over 1 second
20th October 2011
=================
o [BAR] Added chart.ymin - regular and grouped bar charts are supported - not stacked
o [LINE] Multiple filled Line charts now work with the Trace effect
o [METER] Tweaked the Grow animation. Test your charts before upgrading (if you use the Grow animation)
o [MISC] IMPORTANT: Default positioning for titles has changed - see .BC.txt file
o [PIE] Added chart.key.interactive
15th October 2011
=================
o [GAUGE} Added Grow effect. Like the Odo (now) it animates from the last reading, not zero all the time.
o [LINE] Added FoldToCenter effect
o [MISC] Converted crosshairs to use DOM2 event handling
o [MISC] Added: chart.crosshairs.vlines
chart.crosshairs.hlines
o [ODO] Changed Grow animation function so that it animates from the last reading - not constantly from zero
o [PIE] Added .Explode() method to pie chart for programmatically exploding segments
o [RADAR] Added Grow effect
o [SCATTER] Added chart.ylabels.inside
o [WATERFALL] Added Grow effect
11th October 2011
=================
o [NOTE] The Pie chart chart.segments array is being removed (probably November or December) - use obj.angles instead.
o [PIE] IMPORTANT: The Pie chart has been altered so that the start point is now the "north"axis. Please check your
charts - particularly if you use the Pie chart internals. If you want to stick with the older version of the
Pie chart - it's in the libraries/ folder named RGraph.pie.js.old and will be there for a few releases.
You're highly recommended to use the newer version though as the old version will bew only kept for a few
months.
o [PIE] Added RGraph.Effects.Pie.Implode animation - combining it with the RoundRobin animation looks good
o [ROSE] The Rose chart Grow animation also now gradually increases the angle of the segments as well as their size. See
this page for an example: http://www.rgraph.net/examples/index.html Regular and stacked Rose charts are supported
8th October 2011
================

o [GANTT] Added the ability to have multiple "events" per line. For an example see here:
http://www.rgraph.net/examples/gantt.html
Note that if you start adding multiple events then the tooltips order may need attention
o [GAUGE] Added Gauge chart - another meter variant
o [LINE] Added chart.tooltips.hotspot.xonly. This makes the tooltips trigger by the X mouse position only
o [MISC] Not very noticable, but the snap tooltip effect now uses jQuery if it's available.
o [ODO] Note that Firefox 7 had issue with the gradient used in the Odometer border - so you may find that it has changed very
very slightly
o [PIE] Fixed a pie chart bug which presented itself when clicking canvas tags that had nothing to do with RGraph
24th September 2011
===================
o [WEBSITE] Social icons updated
22nd September 2011 (STABLE)
===================

o [MISC] STABLE release
o [SCATTER DOCS] Documented chart.line.linewidth
o [WEBSITE] Added testimonial from Cisco Ireland
18th September 2011
===================
o [LICENSE] If you want to buy multiple licenses (eg you're a web designer with multiple clients that you want
to get RGraph licenses for), then there's now a bulk licenses option with the discount increasing
the more you buy. If you're interested in this then you can inquire about it by emailing
licensing@rgraph.net
o [LINE] Filled line charts and the X axis at the top now works correctly
o [METER] Added Meter chart Grow effect
12th September 2011
===================
o [HBAR] chart.background.grid.autofit has been turned on by default.
o [LINE] Added chart.curvy and chart.curvy.factor. Curvy lines are NOT exact, and the inaccuracy increases with
the severity of the curve. chart.curvy.factor can be a decimal from 0 (not curvy) to 0.5 (quite curvy)
9th September 2011
==================
o [BAR] The background grid autofit has been turned on by default. The number of horizontal grid lines has been
changed to 5.
o [EFFECTS] Fade in now operates over a period of 0.5 seconds
o [LICENSE] Revamped the license page - this should make it clearer

if you're upgrading and you use tooltips in conjunction with the zoom.
o [PIE] Fixed a Pie chart label/seperation bug where chart.exploded is a number
o [ROSE] Added Grow() animation. This only works with regular and stacked Rose charts.
o [SCATTER] You can now have an X scale. If you specify that the X axis should be scaled then you don't have to specify an
xmax - one will be calculated for you. It may not be what you want though - so you might have to specify the
xmax anyway.
o [SCATTER] Minor bug fixed when hiding the lest tick when the X axis is at the right
o [SCATTER] The background grid autofit has been turned on by default. The number of horizontal grid lines has been
changed to 5.
o [WATERFALL] Added ability to have the X axis in the center
o [WATERFALL] The Waterfall property chart.background.grid.autofit now defaults to true (instead of false)
o [ZOOM] Changed the frame rate for the full canvas zoom
30th August 2011
================
o [LINE] Added chart.animation.unfold.initial
o [MISC] Support is now via email - support@rgraph.net - not the forum
27th August 2011 (STABLE)
================
o [MISC] Stable release
25th August 2011
================
o [WEBSITE] Misc website changes
22nd August 2011
================
o [LINE] Added RGraph.Effects.Line.Rise(obj) animation function. This is a nice effect made simple because of the
.Animate() function
o [LINE] A bug has been fixed for stepped line chart, but please be cautious when upgrading
20th August 2011
================
o [MISC] Changed the RGraph.Clear() method to use .clearRect() method
o [LINE] IMPORTANT Significant change to the way that filled multi-line charts are drawn. Formerly
the lines were stacked on top of each other. Normally this wasn't too much of an issue
unless you wanted semi-transparent colours. Because the lines were stacked on top of
each other the colors wouldn't be exactly right. This has now changed so you CAN now use
semi-transparent colors.
As a result the order in which the lines are drawn has been changed, so whilst the data
will remain the same, the "stacking" order if the datasets may change. Also, if you use
an array of shadow colors, they may need reversing.
o [MISC] The download archive now works "out-of-the-box" with IE9. Formerly the DOCTYPE wasn't the first line
in the files so it choked. Only offline IE9 was affected.
o [MISC] Added showcase of requestAnimationFrame(): http://dev.rgraph.net/tests/anim.html

10th August 2011
================
o [ANIM] Revamped the animation page and added the RGraph.Effects object. This allows you to add animation and wipes
to your RGraph charts.
6th August 2011
===============
o [BAR LINE] Tooltips highlighting now works with combined bar/line charts
o [METER] Added chart.centery, chart.centery and chart.radius
o [METER] Added chart.colors.ranges - an alternative to the red/yellow/green areas
o [METER] Added chart.strokestyle - default is null

o [BAR] Fixed a bug with specific labels vertical positioning with a center X axis
o [LINE] Documented chart.noendxtick
o [LINE] Added chart.tickmarks.linewidth
o [LINE] When using specific labels and a ymin, the first label is now placed where "0" would go

o [PIE] Shadow now works correctly with exploded segments
o [SCATTER] Added chart.labels.above, chart.labels.above.size and chart.labels.above.decimals to the Scatter chart
20th July 2011
==============
o [BIPOLAR] Converted tooltips to use the new obj.getBar(e) method.
o [PIE] The option chart.exploded can now be a number, which is then applied to each segment (as well as the prior array)
o [PIE] Outlining now works with exploded segments - http://www.rgraph.net/docs/you-dont-need-to-spend-a-lot-of-money.html
o [BAR] When adding a line chart on top of a bar chart, the following are no longer set.
If you want them you will need to set them yourself (the former values are also shown):
line.Set('chart.noaxes', true);
line.Set('chart.background.barcolor1', 'rgba(0,0,0,0)');
line.Set('chart.background.barcolor2', 'rgba(0,0,0,0)');
line.Set('chart.background.grid', false);
line.Set('chart.ylabels', false);
There are a few things that are still set for you:
chart.gutter.top
chart.gutter.bottom
chart.gutter.left
chart.gutter.right
chart.ymax
o [FUNNEL] Converted tooltips to use the new obj.getSegment(e) method.
o [LINE] The Line chart now has a .__index2__ property which can be used in your ontooltip event handlers. This is the index
in the individual array for a particular line. If you're not using multiple lines in your chart, this won't affect
you.
17th July 2011
==============
o [BAR] Added chart.colors.reverse for reversing the order in which colors are used (stacked bar charts only)
o [FUNNEL] Added a .getSegment(e) method - which greatly simplifies retrieving the segment that has
been clicked on (or the mouse is over etc).

12th July 2011
==============
o [MISC] Stable release
11th July 2011
==============
o [WEBSITE] Website updates
10th July 2011
==============
o [CONTEXT] Added the registry variable: RGraph.Registry.Get('chart.contextmenu').__shape__
This is the underlying hotspot (eg bar/segment/point), if any, that was clicked on.
Objects that have a .getXXX() method now also have a .getShape() method, which is
exactly the same, but can be used if you don't know what object type you have,
(since it's the same name across all object types).
8th July 2011
=============
o [DOCS] Documentation updates
o [COMMON] Fixed a slight bug when formatting negative numbers at 1,000 and over
o [METER] Added Meter options: chart.value.label
chart.value.text.decimals
chart.value.text.units.pre
chart.value.text.units.post
29th June 2011
==============
o [WEBSITE] Website changes
28th June 2011
==============
o [RADAR] The Tradar has been renamed to Radar - you WILL need to update your code slightly.
o [RADAR] Fixed a bug with tooltips and multiple datasets
o [TOOLTIPS] The 'snap' effect now snaps on the first view, moving in from the top left - see the front page line chart
for an example of its use.
25th June 2011
==============
o [LINE] "10 labels" with a chart.ymin value now works with X axis at the top and bottom
o [PIE] The chart.tooltips.coords.adjust property has been removed
o [ZOOM] Added ability to fire the full canvas zoom by just a click - no context menu
23rd June 2011
==============
o [LINE] The chart.tooltips.coords.adjust property has been removed
o [ROSE] The Rose chart getSegment() return value has changed. Instead of just one radius value, there are now two
radius values - the start and end values. This change was necessary to facilitate stacked Rose charts.
Subsequent values have "moved up one" in the array (ie what was index 3 is now 4, what was 4 is now 5
and what was 5 is now 6)
o [SCATTER] The chart.tooltips.coords.adjust property has been removed
21st June 2011
==============
o [DONUT] Added chart.variant.donut.color for the center hole
o [HBAR] The default colors have changed
o [HBAR] Added sequential color support to grouped and stacked HBars
18th June 2011
==============
o [HBAR] Added chart.colors.sequential for regular hbars (not stacked or grouped)
o [HBAR] Converted to .getBar(e) method for tooltips
o [LINE] Added triangle and filledtriangle tickmark types
o [ODO] Added chart.green.solid and documented
o [ODO] Added chart.yellow.solid and documented
o [ODO] Added chart.red.solid and documented
o [ODO] Documented chart.green.color
o [ODO] Documented chart.yellow.color
o [ODO] Documented chart.red.color
o [PIE] Added chart.variant.donut.color - this controls the color of the hole
o [ROSE] Implemented stacked Rose chart (see below)
o [ROSE] Added chart.colors.sequential (which, if you upgrade, you need to set to true to maintain BC)
o [ROSE] When using tooltips, the highlight will now appear "over" the axis labels. This makes the
highlighted segment more identifiable.
o [ROSE] Tooltips can now be a single function, or an array of functions as well as an array of strings
o [ROSE] Added chart.variant - the value can be either null (for a normal or stacked Rose chart) or "non-equi-angular" for a
Rose chart that has unequal segment sizes. See an example here:
http://dev.rgraph.net/tests/2011-07-30/non-equi-angular_rose.html
o [ROSE] Added chart.labels.offset
o [ROSE] Added chart.tooltips.event
o [SCATTER] Added in-graph labels to Scatter chart
The Rose chart has undergone significant changes in order to facilitate stacked and non-equi-angular charts.
In particular, the color handling has changed, and as such you may need to specify chart.colors.sequential in
your chart configurtion to get the colors to behave as they used to. Changing the way colors behave brings the Rose chart
into line with other chart types. Also, the Rose chart .getSegment() return value has changed - now instead of just one radius
value, you get a start radius and end radius value.
7th June 1011
=============
o [LINE] Documented chart.filled.accumulative
o [WEBSITE] Removed redundant checks from graph libraries
4th June 2011 (STABLE)
=============
o [MISC] Stable release - see .BC.txt, and look through this files entries since the last stable release (25-03-2011)
28th May 2011
=============
o [LINE] You may need to adjust your titles vertical positioning using chart.title.vpos
o [MISC] Added example of adding a subtitle to your graph
21st May 2011
=============
o [BIPOLAR] Tooltip handling has changed. If none is set for a particular bar, none will now be shown
o [COMMON] Check your graph titles - the vertical positioning has changed. To reposition you can
use chart.title.vpos
o [HBAR]The X axis title positioning may have changed slightly - if you use it you should check your title is as you expect
o [HBAR] chart.labels.above has been fixed in respect of drawing text in a stacked HBar for sections that it shouldn't do
o [HBAR] Fixed a very minor bug when the chart is redrawn (after being drawn once) and the scale wasn't correctly reset
o [LINE] This chart type may be particularly buggy because of the gutter changes
o [MISC] Individual gutters are now settable with all graph types
o [MISC] The settings chart.width and chart.height are now deprecated in favour of the new individual gutter settings
o [ODO] Added key - helpful for multiple pointers
o [RESIZE] Repositioning the resize handle is no longer necessary with the introduction of independent gutter settings.
Starting with the May release this setting should no longer be used.
o [SCATTER] Added an obj.getPoint(e) method which eases getting the point (if any) that is currently being hovered over
o [WATERFALL] Documented chart.scale.formatter
Keep in mind that individual gutter settings and using chart.width/chart.height are not meant
to be used together - chart.width/chart.height will cease to be user facing properties and will
(starting this release) stop functioning and be removed completely. The addition of individual
gutter settings is a fundamental change so testing of your graphs is imperative. The
requirement of translating to reclaim lost space is reduced (if not eliminated
entirely) with the addition of these settings.
7th May 2011
============
o [API] Added RGraph.Reset() function, which both clears the canvas AND resets any .translate() that has been performed
o [INVOICE] Improved the appearance of the invoice
o [LINE] Added individual gutter settings:
chart.gutter.left
chart.gutter.right
chart.gutter.top
chart.gutter.bottom
Keep in mind that these settings are experimental currently. In particular they may cause dynamic features
not to work 100% correctly.

9th April 2011
==============
o [BAR] Added support for chart.background.image
o [BAR] Added ability to have X axis at the top for entirely negative data sets, eg:
obj.Set('chart.xaxispos', 'top');
o [LED] Added chart.width and chart.height. Also changed the sizing so now the letters should always fit the canvas size
o [LINE] Added support for chart.background.image
o [LINE] Added ability to have X axis at the top for entirely negative data sets, eg:
obj.Set('chart.xaxispos', 'top');
o [MSIE] MSIE 8 now clears to white by default, not transparent
o [PIE] Added chart.tooltips.coords.adjust
o [PIE] Segment separation is now available as a tooltip highlight mode (exploded segments)

o [THERMOMETER] Added chart.text.color
o [THERMOMETER] Added chart.value.label, which allows to not display the label (true/false)
25th March 2011 (STABLE)
===============
o [COMMON] The default for chart.key.halign is now null, by default the position for the
key depends on the position of the Y axis
o [COMMON] Changed chart.title.yaxis.align to chart.title.yaxis.position
o [MSIE] Positioning tweaks for IE9 final
20th March 2011
===============
o [LINE] Added workaround for Chrome bug when specifying different line widths for lines
o [MISC] Added chart.key.halign (when using graph mode) which can be left or right (default)
o [TRADAR] Fixed tradar and interactive adjusting (thrown out by the addition of multiple datasets)
12th March 2011
===============
o [COMMON] The RGraph.Clear() function has been changed to a transparent colour to transparent instead of white. Also,
a new event has been added called onclear which fires when the function is called. You can use this function
to draw a white (or a color of your choice) rectangle over the canvas. Effectively clearing the canvas to
your color, for example:
function myClear(obj)
{
obj.context.beginPath();
obj.context.fillStyle = 'white';
obj.context.fillRect(-10,-10,obj.canvas.width + 20, obj.canvas.height + 20);
obj.context.fill();
}
DO NOT simply use the RGraph.Clear() function in the onclear event listener function, as you will create an
infinite loop.
o [COMMON] Added chart.title.yaxis.align to the common background code. This is usable by:
- Bar
- Line
- Scatter
o [LINE] A bug has been fixed that is apparent when you're using chart.outofbounds and have null values. If you have this
combination, please test your graphs! An example is here: http://dev.rgraph.net/tests/null.html
o [ODO] Added chart.border.color1
o [ODO] Added chart.border.color2
o [ODO] Added chart.border.color3

chart.tickmarks.small.num
chart.tickmarks.big.num
chart.tickmarks.small.color
chart.tickmarks.big.color
o [RESIZING] Tooltips for the icons are now limited to Google Chrome and MSIE because of reliability issues. The cursor will
still change in all browsers though
o [THERMOMETER] Added chart.title.side
o [TRADAR] Added multiple dataset support. eg: http://www.rgraph.net/examples/tradar.html
o [TRADAR] Added key
5th March 2011
==============
o [COMMON] The default color for by the RGraph.Clear() function has been changed to transparent.
o [COMMON] The RGraph.getSegment() function has been moved to be a method of both the Rose and the Pie charts, instead of part
of the common object. ie Supposing your object is called myObj, it will now be myObj.getSegment(e), instead of
RGraph.getSegment(e)
o [INVOICE] Added Paypal button to invoice
o [PIE] Added exploded segments. http://www.rgraph.net/docs/animation_segments.html Certain Pie chart options won't work
with this feature
o [THERMOMETER] Added initial implementation of this visual variation on the progress bar

28th January 2011 (STABLE)
=================
o [BAR] Added chart.background.grid.autofit.align, for making the grid lines line up with the ticks. Any chart.hmargin will
throw the alignment out.
o [DOCS] Added note to animation page about CSS vs
