ChartDirector 6.2 (.NET Edition)

Cylinder Bar Shape




This example demonstrates bars of cylinder shape.

ChartDirector supports bars in cylindrical or arbitrary polygonal shapes. The shape are specified using BarLayer.setBarShape or BarLayer.setBarShape2. In this example, the cylindrical shape is illustrated.

See Shape Specification on how built-in and custom shapes are defined in ChartDirector.
