ChartDirector 7.0 (Java Edition)

3D Scatter Axis Types




This example demonstrates different axis scale types for the 3D scatter charts. It also demonstrates using different symbol shapes.

Like an XYChart, in a ThreeDScatterChart, the axis scale can represent numbers, date/time or labels. In this example, the x-axis uses a date/time scale, the y-axis uses a label based scale, and the z-axis uses a numeric scale.
