A configurable class that can be used to represent custom legend options for the chart, which can then be set on the chart (via the {@link Chart#setLegend(Legend)} method.)The legend is a box containing a symbol and name for each series item or point item in the chart. Example usage:
chart.setLegend( new Legend() .setBorderColor("#CC0000") .setLayout(Legend.Layout.HORIZONTAL) );
