The Scatter 3D Chart Type

3D Scatter Charts can be created using the SCIScatterRenderableSeries3D type.

Scatter Chart 3D

NOTE: Examples for the Scatter Series 3D can be found in the SciChart iOS Examples Suite as well as on GitHub:

The Scatter Series 3D requires a shape to be specified using the Point Markers 3D. SciChart provides several shapes out of the box:

Flat-Texture PointMarkers Mesh (Volumetric) PointMarkers
SCITrianglePointMarker3D SCIPyramidPointMarker3D
SCIQuadPointMarker3D SCICubePointMarker3D
SCIEllipsePointMarker3D SCISpherePointMarker3D
SCIPixelPointMarker3D SCICylinderPointMarker3D
SCICustomPointMarker3D

It is also possible to define custom texture for the Point Markers via the SCICustomPointMarker3D. Please refer to the PointMarkers 3D API article to learn more. You can also override colors of the Point Markers 3D individually using The MetadataProvider API.

Create a 3D Scatter Series

To create a SCIScatterRenderableSeries3D, use the following code:

SCINumericAxis3D *xAxis = [SCINumericAxis3D new]; xAxis.growBy = [[SCIDoubleRange alloc] initWithMin:0.1 max:0.1]; SCINumericAxis3D *yAxis = [SCINumericAxis3D new]; yAxis.growBy = [[SCIDoubleRange alloc] initWithMin:0.1 max:0.1]; SCINumericAxis3D *zAxis = [SCINumericAxis3D new]; zAxis.growBy = [[SCIDoubleRange alloc] initWithMin:0.1 max:0.1]; SCIXyzDataSeries3D *ds = [[SCIXyzDataSeries3D alloc] initWithXType:SCIDataType_Double yType:SCIDataType_Double zType:SCIDataType_Double]; for (int i = 0; i < 250; ++i) { double x = [SCDDataManager getGaussianRandomNumber:15 stdDev:1.5]; double y = [SCDDataManager getGaussianRandomNumber:15 stdDev:1.5]; double z = [SCDDataManager getGaussianRandomNumber:15 stdDev:1.5]; [ds appendX:@(x) y:@(y) z:@(z)]; } SCISpherePointMarker3D *pointMarker = [SCISpherePointMarker3D new]; pointMarker.fillColor = 0xFF32CD32; pointMarker.size = 10.0; SCIScatterRenderableSeries3D *rs = [SCIScatterRenderableSeries3D new]; rs.dataSeries = ds; rs.pointMarker = pointMarker; [SCIUpdateSuspender usingWithSuspendable:self.surface withBlock:^{ self.surface.xAxis = xAxis; self.surface.yAxis = yAxis; self.surface.zAxis = zAxis; [self.surface.renderableSeries add:rs]; [self.surface.chartModifiers add:ExampleViewBase.createDefault3DModifiers]; }];
let xAxis = SCINumericAxis3D() xAxis.growBy = SCIDoubleRange(min: 0.1, max: 0.1) let yAxis = SCINumericAxis3D() yAxis.growBy = SCIDoubleRange(min: 0.1, max: 0.1) let zAxis = SCINumericAxis3D() zAxis.growBy = SCIDoubleRange(min: 0.1, max: 0.1) let dataSeries = SCIXyzDataSeries3D(xType: .double, yType: .double, zType: .double) for _ in 0 ..< 200 { let x = SCDDataManager.getGaussianRandomNumber(5, stdDev: 1.5) let y = SCDDataManager.getGaussianRandomNumber(5, stdDev: 1.5) let z = SCDDataManager.getGaussianRandomNumber(5, stdDev: 1.5) dataSeries.append(x: x, y: y, z: z) } let pointMarker = SCISpherePointMarker3D() pointMarker.fillColor = 0xFF32CD32; pointMarker.size = 10.0 let rs = SCIScatterRenderableSeries3D() rs.dataSeries = dataSeries rs.pointMarker = pointMarker rs.selectedVertexColor = 0xFF00FF00 rs.metadataProvider = SCIDefaultSelectableMetadataProvider3D(seriesType: SCIScatterRenderableSeries3D.self) let orbitModifier = SCIOrbitModifier3D() orbitModifier.gestureRecognizer?.minimumNumberOfTouches = 2 SCIUpdateSuspender.usingWith(surface) { self.surface.xAxis = xAxis self.surface.yAxis = yAxis self.surface.zAxis = zAxis self.surface.renderableSeries.add(rs) self.surface.chartModifiers.add(ExampleViewBase.createDefault3DModifiers()) }
var dataManager = DataManager.Instance; var dataSeries3D = new XyzDataSeries3D<double, double, double>(); for (int i = 0; i < 100; i++) { double x = dataManager.GetGaussianRandomNumber(5, 1.5); double y = dataManager.GetGaussianRandomNumber(5, 1.5); double z = dataManager.GetGaussianRandomNumber(5, 1.5); dataSeries3D.Append(x, y, z); } var rSeries3D = new SCIScatterRenderableSeries3D { DataSeries = dataSeries3D, PointMarker = new SCISpherePointMarker3D { FillColor = ColorUtil.Lime, Size = 10.0f }, }; using (Surface.SuspendUpdates()) { Surface.XAxis = new SCINumericAxis3D { GrowBy = new SCIDoubleRange(0.1, 0.1) }; Surface.YAxis = new SCINumericAxis3D { GrowBy = new SCIDoubleRange(0.1, 0.1) }; Surface.ZAxis = new SCINumericAxis3D { GrowBy = new SCIDoubleRange(0.1, 0.1) }; Surface.RenderableSeries.Add(rSeries3D); Surface.ChartModifiers.Add(CreateDefault3DModifiers()); Surface.Camera = new SCICamera3D(); }

In the code above, a Scatter Series instance is created and assigned to draw the data provided by the ISCIDataSeries3D assigned to it. The Scatters 3D are drawn with a PointMarker provided by the SCISpherePointMarker3D instance. Finally, the 3D Scatter Series is added to the ISCIChartSurface3D.renderableSeries collection.

Paint Scatters With Different Colors

Is SciChart, you can draw each scatter of the Scatter Series 3D with the different color using the MetadataProvider API. To use MetadataProvider for scatters 3D - a custom ISCIPointMetadataProvider3D has to be provided to the ISCIRenderableSeries3D.metadataProvider property. Also, there is SCIPointMetadataProvider3D provided out of the box, as a general case for Scatter Series 3D.

Individually colored Scatter Series 3D are also known as Bubble 3D Chart. Please visit the corresponding article for more information about it.

NOTE: To learn more about coloring ISCIRenderableSeries3D points individually - refer to the MetadataProvider API article for more info.
