ChartDirector Ver 3.1 (PHP Edition Edition)

Depth Area Chart




ChartDirector allows a XY chart to containing multiple layers of the same or different types. In this example, all layers are 3D area layers. The areas are filled using semi-transparent colors to avoid the area on the front hiding the areas at the back.
