The Scatter 3D Chart Type

Examples for the Scatter 3D Chart can be found in the SciChart WPF Examples Suite which can be downloaded from the SciChart Website or our SciChart.WPF.Examples Github Repository.

3D Scatter Charts are provided by the ScatterRenderableSeries3D type, which requires a PointMarker.

The ScatterRenderableSeries3D supports multiple pointmarkers, including:

3D Marker Types

SpherePointMarker3D - a 3D Sphere at each point
CubePointMarker3D - 3D Cube at each point
PyramidPointMarker3D - a 3D Pyramid at each point
CylinderPointMarker3D - a 3D Cylinder at each point

Fast 2D Marker types

PixelPointMarker3D - a single pixel at each point
QuadPointMarker3D - a Quad (flat square) facing the camera at each point
EllipsePointMarker3D - a flat ellipse facing the camera at each point
TrianglePointMarker3D - a flat triangle facing the camera at each point
CustomPointMarker3D - custom flat textured markers facing the camera at each point

Declaring a 3D Scatter Series

To declare a 3D Scatter Series with PointMarker use the following code:

    var xyzDataSeries3D = new XyzDataSeries3D<double>();
    for (var i = 0; i < Count; i++)

}

NOTE: You can also declare RenderableSeries using full MVVM (series ViewModels) using the SeriesBinding MarkupExtension. Please see MVVM DataSeries / RenderableSeries API for more details.

Coloring Individual Scatter Points

Scatter points may be colored or scaled individually using the PointMetada3D API. To do this, set a PointMetada3D instance at the data-point as follows:

Example Title	Copy Code
xyzDataSeries3D.Append(x, y, z, new PointMetadata3D(Colors.Blue, 1.0d));
