ChartDirector 6.2 (.NET Edition)

Polygon Bar Shapes




This example demonstrates bars of various polygonal shapes.

ChartDirector supports bars in cylindrical or arbitrary polygonal shapes. This is specified by using BarLayer.setBarShape and BarLayer.setBarShape2. In this example, various polygonal shapes are illustrated.

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

For demonstration, in this example each bar is of a different shape. BarLayer.setBarShape and BarLayer.setBarShape2 also supports setting the bar shapes based on data groups (or data sets) or data item position. For an example, see Multi-Shape Bar Chart.
