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:

Thank you Yeray.

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());
				}
			}
		});
