This example illustrates controlling the fonts, colors, rotation angles, background box, etc, for the text containing objects in ChartDirector.

The chart title, y-axis title, y-axis labels, x-axis labels, legend keys, and the data labels are configured with different fonts and colors, and have different background and 3D border effects. The y-axis labels are appended with "Mbytes" as the unit. The x-axis labels are rotated 45 degrees.

Note that starting with ChartDirector Ver 3.0, you can use CDML to produce more sophisticated formatting effects than demonstrated in this example.
