Examples of org.jfree.chart.renderer.xy.XYLineAndShapeRenderer$State

org.jfree.chart.renderer.xy.XYLineAndShapeRenderer
Records the state for the renderer. This is used to preserve state information between calls to the drawItem() method for a single chart drawing.

        // have a renderer (i.e. falls back to renderer 0)
