ChartDirector 6.2 (.NET Edition)

Depth Area Chart




This example demonstrates using multiple area layers with semi-transparent colors to create a depth area chart.

ChartDirector allows an XYChart to containing multiple layers of the same or different types. In this example, all layers are 3D area layers. The areas are filled using semi-transparent colors to avoid the area on the front hiding the areas at the back.
