Remarks
This class provides numerous conversion functions and also exposes a GDI+ Graphics object. Note that when rendering as SVG, use of the Graphic object for custom drawing will not be included as part of the SVG document.
Note that by default ChartGraphics functions usually take absolute coordinates, so the conversion methods of this class should be useful when performing drawing operations.
A ChartGraphics object is exposed as an argument in the ChartPaintEventArgs class, making it easy to perform custom drawing in the Paint and BackPaint events.
IMPORTANT: If significant changes are made to the default behavior of the Graphics object then the chart image and its associated elements may be drawn erratically (e.g. positioning may be changed, etc.). We highly recommend getting to know GDI+ very well before making significant changes to the Graphics object's properties.
