Examples of org.jfree.chart.renderer.category.LineAndShapeRenderer

org.jfree.chart.renderer.category.LineAndShapeRenderer
A renderer that draws shapes for each data item, and lines between data items (for use with the {@link CategoryPlot} class).The example shown here is generated by the LineChartDemo1.java program included in the JFreeChart Demo Collection:

    final CategoryPlot cpl = chart.getCategoryPlot();
    final CategoryItemRenderer renderer = cpl.getRenderer();
    renderer.setStroke(translateLineStyle(lineWidth, lineStyle));
    if (renderer instanceof LineAndShapeRenderer)
    {
      final LineAndShapeRenderer shapeRenderer = (LineAndShapeRenderer) renderer;
      shapeRenderer.setShapesVisible(isMarkersVisible());
      shapeRenderer.setBaseShapesFilled(isMarkersVisible());
    }


  }
