ChartDirector 6.2 (.NET Edition)

Depth Bar Chart




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

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