ChartDirector 7.1 (.NET Edition)

Exploded Pie Chart




This example demonstrates a pie chart with all sectors exploded. It also demonstrates many effects, such as gradient color background, rounded frame, soft drop shadow, custom sector colors, sector gradient shading, thick sector border, and using CDML and Parameter Substitution and Formatting to format sector labels.
