3D Scatter Chart (1)

This example demonstrates the basic steps in creating 3D scatter charts.

Create a ThreeDScatterChart object using ThreeDScatterChart.ThreeDScatterChart.
Specify the position and size of the plot region using ThreeDChart.setPlotRegion.
Add a scatter group to the chart using ThreeDScatterChart.addScatterGroup. In this example, the symbol color is set to SameAsMainColor, which means the color depends on the z-coordinate as according to the color axis (color legend). The color axis can be accessed using ThreeDChart.colorAxis.
Set the position of the color axis (the color legend) using ThreeDChart.setColorAxis.
Add chart and axis titles using BaseChart.addTitle and Axis.setTitle.
Generate the chart using BaseChart.makeChart.
