Clickable legends?

[rannic]

Pre-1.0, when you clicked on a legend, a ChartMouseEvent was generated whose Entity was a LegendItemEntity. Of course, now that legends are no different from any other title, these events are no longer thrown. I tried using the LegendTitle's getBounds() and related methods, but they return zeros. Has anyone come up with a good way to handle clicking on legends?

I would definitely be interested in this as well...

Has anybody found a solution for this by now. I only can get the sizes of the single LegendLabelBlocks, but have by now not found a way to retrieve to position of the legendtitle...

Looks OK to me in 1.0.14:

LegendItemEntity java.awt.geom.Rectangle2D$Double[x=249.0,y=458.515625,w=38.0,h=18.484375]
LegendItemEntity java.awt.geom.Rectangle2D$Double[x=289.0,y=458.515625,w=56.0,h=18.484375]
LegendItemEntity java.awt.geom.Rectangle2D$Double[x=347.0,y=458.515625,w=44.0,h=18.484375]

Code: Select all

chartPanel.addChartMouseListener(new ChartMouseListener() {

    @Override
    public void chartMouseClicked(ChartMouseEvent e) {
        String name = e.getEntity().toString().split(":")[0];
        System.out.println(name + " " + e.getEntity().getArea());
    }

    @Override
    public void chartMouseMoved(ChartMouseEvent e) {}

});
