JFreeChart: how to change XYPlot foreground color?

The JFreeChart XYPlot background color is chang开发者_开发技巧ed using setBackgroundPaint() but there doesn't seem to be a corresponding setForegroundPaint().

XYPlot plot = (XYPlot) chart.getPlot();
plot.setBackgroundPaint(Color.BLACK);

How is the foreground color (the plot) changed?

eg:

XYItemRenderer renderer = plot.getRenderer();
renderer.setSeriesPaint(0, Color.CYAN);
