[New] Compatible with RB3-5.5 and greater
[New] Polygons and pictures now rotate.
[Chg] Demo project now shows an example of graphing real-time data.
[Fix] Bug in theRepositionNodes method of cCurve class. Thanks Ben Rancourt.
v1.7 Released 1/12/2004
[Nte] Now requires RB 5.5
[Fix] Windows DoubleClick time is now returned in ticks rather than milliseconds. Also added LINUX support here when compiled with RB 5.5.4.
[Opt] Faster node scanning on all platforms.
[Opt] Faster node tooltip scanning on all platforms.
[Chg] The node tooltip under Windows now looks like a normal windows help tag.
[Fix] The node tooltip under MacOS now appears inthe correct position on multi-screen computers.

[Chg] cText - Removed the now superfluous textSize and TextFont properties.
v2.0 Released 25 April 2005

[New] GraphPro::Copy This method copies the graph to the clipboard
[New] cCurve.PieShowPerc as boolean. This writeable property determines if the pie labels show the percentage.
[New] cCurve.PieShowLabel as boolean. This writeable property determines if the pie labels are displayed.
[New] GraphPro::DrawGraph - This can be called to quickly refresh the graph without an erasebackground call. The alternative is to call ChartResized which is the complete refresh including a recalculation of some statistical parameters.
[Opt] Faster node scanning on all platforms.
[New] New cCurve property, PieScale as double. Allows the pie graph scaling to be changed (see the demo app).
[Chg] Demo app has a more sensible icon.

[Chg] The text of the legend can be overridden by simply changing the legend.text as string property.
[New] New add node method - GraphPro.AddNode(X as double, Y as double, NodeName as string)
[New] New add cCurve property - cCurve.pieYTotal as double. If you want to set an artificial Y total (rather than the summation total) then you can change this number and it will be used as the total in calculating the pie arcs.
[Chg] Reverted to the v1.5 Pie drawing algorithm. This allowed MouseOverNode events to fire correctly.
[Chg] Temporarily disabled some Pie graphs features, namely spin, Tilt and depth options.

[Fix] 2D Column spacing Help tags now work better.
[New] New property cAxis.MajorTickStrings(-1) as string. This array of strings will be drawn at the Major Tick Marks if it is populated. This property is set via the method cGraphPro::AXISSetMajorTickStrings(theAxis as string, vList() as string)
[New] cCurve.PieCentreX as integer This is the centre of the pie graph. Only positive values are valid, otherwise the pie graph is drawn in the centre.
[New] cCurve.PieCentreY as integer This is the centre of the pie graph. Only positive values are valid, otherwise the pie graph is drawn in the centre.
[New] Bar Curves can now show the node label on top of each column.
[Fix] Thick curve lines now join the dots from the centre of the line.
[New] New Function cGraphPro::DrawLegend(g as graphics, theLegend as cLegend) As boolean. Return true to completely override the drawing of the cLegend. You can draw anything you want into this graphics port.
