org.jfree.chart.renderer.category.MinMaxCategoryRenderer
Renderer for drawing min max plot. This renderer draws all the series under the same category in the same x position using objectIcon and a line from the maximum value to the minimum value. For use with the {@link CategoryPlot} class. The example shown here is generated bythe MinMaxCategoryPlotDemo1.java program included in the JFreeChart Demo Collection:

            sbr.setErrorIndicatorPaint(this.errorIndicatorPaint);
        }


        // MinMaxCategoryRenderer
        if (renderer instanceof MinMaxCategoryRenderer) {
            MinMaxCategoryRenderer mmcr = (MinMaxCategoryRenderer) renderer;
            mmcr.setGroupPaint(this.errorIndicatorPaint);
        }
    }
