 29th July 2011 (STABLE)
 ==============
  o [BAR] Added chart.noendxtick
  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

 25th July 2011
 ==============
  o [CONTEXT] Added onbeforecontextmenu RGraph event
  o [KEY] Noted Line chart interactive key
  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.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).
  o [LINE] Added chart.key.interactive - this allows you click on a key item and it will be highlighted on the chart
  o [TOOLTIPS] Small fix to snap effect when you have multiple charts one one page, both with tooltips
  o [TOOLTIPS] The default CSS has been altered for tooltips. This affects all chart types. The changes are:
                o There is now no CSS border to the tooltip
                o The toltip is now transparent a small amount (opacity=0.9)
                o The tooltip shadow X & Y offsets are now zero

 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.
  o [MODALDIALOG] Added an example of covering the scroll bars to the ModalDialog page
  o [ODO] Kength of extra pointers is now supported, eg: odo.Set('chart.needle.extra', [[16, 'yellow', 50]]);
  o [WATERFALL] Added this new chart type
  o [WEBSITE] Changed pages to use uncompressed version of ExCanvas - now works offline

 30th April 2011

 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:

  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 [SCATTER] Added support for chart.background.image
  o [SCATTER] Documented chart.ylabels.invert
  o [THERMOMETER] Added adjusting

 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
  o [ROSE] Corrected a bug in the Rose chart, introduced in the prior beta
  o [METER] Added the following tickmark controls to the Meter chart:
             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

           if you're expecting decimals
 o [LICENSING] If you prefer you can now use PayPal instead of Google Checkout to buy an RGraph license:
               http://www.rgraph.net/docs/licensing.html#paypal
  o [LINE] Fixed a bug with null points still showing tooltips
  o [MISC] The key handling has been rewritten. There is now a documentation page about keys:
           http://www.rgraph.net/docs/keys.html
  o [MISC] Added default key properties to all relevant graph types - the key has been completely rewritten and as such,
           you should check your graphs are as you expect. You may neeed to slightly adjust your key coordinates for example.
  o [SCATTER] Added option to have vertical bars (much like the horizontal bars option)

    | IMPORTANT !                                                                                                      |
    | Every single one of the property names has been changed to be a little more unified. The new format is now       |
    | "chart.xxx" where xxx is the actual name. Some of the names have been changed completely, eg. "chart.text.size", |
    | which was formerly "textheight", whilst others only marginally. This was necessary to bring some semblance of    |
    | uniformity to the RGraph properties across all of the libraries, make it look a bit more "proffessional" and     |
    | provide plenty of scope for future properties.                                                                   |
    |                                                                                                                  |
    | You should also note that as of this release (14th March 2009) that RGraph has been changed to use the canvas    |
    | text and shadow APIs. This may mean you needing to upgrade your browser if you want to use the latest version.   |
    | At the time of writing, this meant Firefox 3.1b2, Safari 4 and Chrome 2. If you don't wish to upgrade your       |
    | browser, or need Opera support, then you will need to remain on the 28th February 2009 version.                  |
