ChartDirector 6.2 (.NET Edition)

Text Styles and Colors (2)




This example demonstrates controlling text style and colors in various text containing objects (chart and axis titles, axis labels, legend keys, data labels, etc).

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 since ChartDirector Ver 3.0, you may use CDML to produce more sophisticated formatting effects than demonstrated in this example.
