ChartDirector 7.0 (Java Edition)

Rotated Pyramid Chart




This example demonstrates a semi-transparent pyramid viewed at elevation and rotation angles. It also demonstrates adding a legend box to the pyramid chart.

The elevation and rotation angles are set using PyramidChart.setViewAngle. The legend box is added using BaseChart.addLegend. Semi-transparent colors are used to make the pyramid semi-transparent.
