Chart Background Paint
You can change the java.awt.Paint implementation used for your charts. The default implementation used by jCharts is java.awt.Color.white.
GradientPaint paint= new GradientPaint( 250, 0, Color.white, 250, 800, new Color( 0, 255, 255, 220 ) ); chartProperties.setBackgroundPaint( paint );
You probably saw the Legend, and wondered why it shares the same background as the Chart. Well, that is by design! The Legend, by default, has no background. We will go over how to assign a Legend Background Paint in the Legend section.
