Legends and Tooltips

Thank you for your answer
Now I have a question about Legends and Tooltips:
I want to
limit the number of Legend Entries - but
these Entries, which were affected by limitation should be viewable through an "Legend-Tab". That means there should be a symbol right of the entries, I can tab on it, and then I should see the remaining Legend Entries.
An Example:

Hello again,
You could hide the main legend and then use 2 dummy series (hidden and with a subset of the point in the main series). Then you could use 2 ExtraLegend tools and show these legends. Here you have a simple example:
Code: Select all
Pie pie1 = new Pie(tChart1.getChart());
pie1.fillSampleValues();
pie1.setCircled(true);
tChart1.getLegend().setVisible(false);
Pie dummy1 = new Pie(tChart1.getChart());
Pie dummy2 = new Pie(tChart1.getChart());
dummy1.setVisible(false);
dummy2.setVisible(false);
for (int i=0; i<pie1.getCount(); i++) {
if (i<4)
dummy1.add(i, pie1.getYValues().getValue(i), pie1.getLabels().getString(i), pie1.getValueColor(i));
else
dummy2.add(i, pie1.getYValues().getValue(i), pie1.getLabels().getString(i), pie1.getValueColor(i));
}
extraleg1 = new ExtraLegend(tChart1.getChart());
extraleg1.setSeries(dummy1);
extraleg1.getLegend().setAlignment(LegendAlignment.BOTTOM);
extraleg1.getLegend().setCustomPosition(true);
extraleg1.getLegend().setLeft(60);
extraleg1.getLegend().setTop(600);
extraleg2 = new ExtraLegend(tChart1.getChart());
extraleg2.setSeries(dummy2);
extraleg2.getLegend().setCustomPosition(true);
extraleg2.getLegend().setLeft(310);
extraleg2.getLegend().setTop(545);
extraleg2.getLegend().setVisible(false);
tChart1.addChartMouseListener(new ChartMouseAdapter() {
@Override
public void backgroundClicked(ChartMouseEvent e) {
if (extraleg1.getLegend().clicked(e.getPoint()) > -1) {
extraleg2.getLegend().setVisible(!extraleg2.getLegend().getVisible());
}
}
});
