Usage

From source file:gda.plots.SimpleLegendGraphic.java

/**

 * returns a non-null BlockResult containing the entity.

 * @return a BlockResult containing a StandardEntityCollection containing the SimpleLegendEntity

@Override
public Object draw(Graphics2D g2, Rectangle2D area, Object params) {

    draw(g2, area);

    ChartEntity entity = null;

    // method. The area has to be transformed into the actual coordinates
    // of the overall ChartPanel for the MouseEvents to work properly.

    BlockResult result = new BlockResult();
