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.
Assign the chart to the WebChartViewer using WebChartViewer.setChart, and insert it to the web page using WebChartViewer.renderHTML.

// Set the center of the plot region at (350, 280), and set width x depth x height to 360 x 360 x
// 270 pixels
c.setPlotRegion(350, 280, 360, 360, 270);

// Add a scatter group to the chart using 11 pixels glass sphere symbols, in which the color depends
// on the z value of the symbol
c.addScatterGroup(xData, yData, zData, "", Chart.GlassSphere2Shape, 11, Chart.SameAsMainColor);

// Add a color axis (the legend) in which the left center is anchored at (645, 270). Set the length
// to 200 pixels and the labels on the right side.
c.setColorAxis(645, 270, Chart.Left, 200, Chart.Right);

// Set the x, y and z axis titles using 10 points Arial Bold font
c.xAxis().setTitle("X-Axis Place Holder", "Arial Bold", 10);
c.yAxis().setTitle("Y-Axis Place Holder", "Arial Bold", 10);

// Output the chart

// Include tool tip for the chart
viewer.setImageMap(c.getHTMLImageMap("", "", "title='<*cdml*>x={x|p}, y={y|p}, z={z|p}'"));
