JFreeChart BarChart -> NO gradient

Question

my bar chart is always drawn with a gradient color by default. I just want a simple color without any styled effects.

Can anyone help ?

Code

Answer 1

The source code for an older version of org.jfree.chart.demo.BarChartDemo1 shows how to set the series colors. Just specify plain colors instead of gradients.

renderer.setSeriesPaint(0, Color.red);
renderer.setSeriesPaint(1, Color.green);
renderer.setSeriesPaint(2, Color.blue);

Correction: The key to @Jes's helpful answer may be found in the initialization of defaultBarPainter in BarRenderer.
