Paint Styles
Designer's paint object editor depicted below allows you to define the chart's paint. The palette defines the default set of colors that can be overriden on the per series or per element basis. When you use color spaces, the palette colors appear on top of the color space popup. WebCharts3D support five different paint types including two gradient types each of which can be vertical or horizontal. To change the gradient range you can drag the handles located below the paint preview area.
For the detailed description of the paint attributes please refer to the paint style class MxPaintStyle.
