ChartDirector 7.0 (ASP/COM/VB Edition)

Multi-Depth Pie Chart




This example demonstrates a 3D pie chart where sectors have different 3D heights.

Instead of using PieChart.set3D to set a single 3D depth for all sectors, in this example, PieChart.set3D2 is used to set different depths for the sectors with an array of integers.
