ChartDirector 6.1 (Java Edition)

Text Styles and Colors




This example demonstrates various text styles, text colors, background colors and text box border effects.

In the chart above, 3 different pattern colors (wallpapers) are used for the chart background, legend box background and chart title background. In addition, the chart title, sector labels, and legends all have different fonts, text colors, background colors, and border styles.
