SciChart Android 3D Tutorial - Create a simple Scatter Chart 3D

In this SciChart Android 3D tutorial, you’ll learn to:

Adding 3D Axes to the SciChartSurface3D

Once you have added a SciChartSurface3D into your Fragment, you will not see anything drawn because you need to add axes. This is important: that three axes X, Y and Z has to be added to your surface.This is a bare minimum to see drawn grid on your device.

surface.setXAxis(new NumericAxis3D());
surface.setYAxis(new NumericAxis3D());
surface.setZAxis(new NumericAxis3D());

Empty SciChartSurface3D

Adding 3D Renderable Series

Now, we would like to see something more than just empty grid, e.g. Scatter 3D Chart. To draw some data in chart we need to create 3D DataSeries and RenderableSeries. The DataSeries is a class which is responsible for storing data which should be displayed and RenderableSeries is a class that determines how data should be visualized by chart.

First, let's declare the 3D DataSeries and generate some data for it:

final XyzDataSeries3D dataSeries = new XyzDataSeries3D(Double.class, Double.class, Double.class);
for (int i = 0; i < 200; i++) {
    final double x = getGaussianRandomNumber(5.0, 1.5);
    final double y = getGaussianRandomNumber(5.0, 1.5);
    final double z = getGaussianRandomNumber(5.0, 1.5);
    dataSeries.append(x, y, z);
}

The next step is to create 3D RenderableSeries. In our case we're going to display data as a point cloud using Scatter Series 3D, which is represented by the ScatterRenderableSeries3D:

final SpherePointMarker3D pointMarker = new SpherePointMarker3D();
pointMarker.setFill(0xFF32CD32);
pointMarker.setSize(10.0f);

final ScatterRenderableSeries3D rSeries = new ScatterRenderableSeries3D();
rSeries.setDataSeries(dataSeries);
rSeries.setPointMarker(pointMarker);

Finally, we need to add newly created series into the renderableSeries collection, like so:

Collections.addAll(surface.getRenderableSeries(), rSeries);

Which will render the following Scatter Chart 3D:

3D Scatter Chart

Note

Please note that we've added axes and renderableSeries to SciChartSurface3D inside using(ISuspendable suspendable, Runnable runnable) block. This allows to suspend surface instance and refresh it only one time after you finished all needed operations. That's highly recommended technique, if you want to omit performance decrease due to triggering refreshes on every operation which could be performed in one batch.
