Examples of org.jfree.chart.title.LegendTitle

org.jfree.chart.title.LegendTitle
A chart title that displays a legend for the data in the chart.
The title can be populated with legend items manually, or you can assign a reference to the plot, in which case the legend items will be automatically created to match the dataset(s).

      chart.removeLegend();
    }
    //if true format legend
    else
    {
      final LegendTitle chLegend = chart.getLegend();
      if (chLegend != null)
      {
        final RectangleEdge loc = translateEdge(legendLocation.toLowerCase());
        if (loc != null)
        {
          chLegend.setPosition(loc);
        }
        if (getLegendFont() != null)
        {
          chLegend.setItemFont(Font.decode(getLegendFont()));
        }
        if (!isDrawLegendBorder())
        {
          chLegend.setBorder(BlockBorder.NONE);
        }
        if (legendBackgroundColor != null)
        {
          chLegend.setBackgroundPaint(legendBackgroundColor);
