Description yeray alonso 2018-02-23 07:13:27 EST 
NearestPoint tool returns Null points as if they were visible.
Here a simple example:


		tChart1.getAspect().setView3D(false);
		tChart1.getLegend().setVisible(false);

		FastLine fast1 = new FastLine(tChart1.getChart());
		for (int i = 0; i < 2000; i++) {
			if (i == 1000)
				fast1.addNullXY(i, 200);
			else
				fast1.add(i, 100);
		}

		fast1.setTreatNulls(TreatNullsStyle.DONOTPAINT);

		tChart1.getAxes().getBottom().setMinMax(0, 2000);
		tChart1.getAxes().getLeft().setMinMax(0, 300);
		
		NearestPoint nearest1 = new NearestPoint(tChart1.getChart());
		nearest1.getPen().setColor(Color.red);
		nearest1.setSeries(fast1);
