Vaadin Charts Scatter 3D Example

Flow
1

Hi there,
Vaadin Charts is fine so far. Thank you for the great components! But now, I’ve found a serious problem with Scatter 3D. If my dataset is larger then arount 1500 entries or so, the chart display “No Data” … After a lot off digging in the code, I’ve found no solution.

But I’ve tested it with Scatter 3D example from https://demo.vaadin.com/charts/#Basic3DScatter. Setup with 5000 random points (see below) and …
don’t work! “No Data”. So what can I do to keep things working, also with “larger” (2000 Points isn’t large!) datasets?!?

Please help!

private void fillSeries(DataSeries higherX, DataSeries higherY,
							DataSeries higherZ) {
		Random random = new Random(7);
		for (int i = 0; i < 5000; i++) {
			double lng = random.nextDouble() * 2 * Math.PI;
			double lat = random.nextDouble() * Math.PI - Math.PI / 2;
			double x = Math.cos(lat) * Math.sin(lng);
			double y = Math.sin(lat);
			double z = Math.cos(lng) * Math.cos(lat);

			DataSeriesItem3d point = new DataSeriesItem3d(x, y, z);
			if (x > y && x > z) {
				higherX.add(point);
			} else if (y > x && y > z) {
				higherY.add(point);
			} else {
				higherZ.add(point);
			}
		}
