    A Graphics Path chart displays an arbitrary figure defined by lines and bezier segments. The following figure shows several graphics path series inside a chart that are used to draw figures at different scale coordinates:

    Figure 1.

     Creating a Polar Range series

    Graphics Path series are represented by the NGraphicsPathSeries type. An instance of this type must be added to the series collection of a Cartesian Chart).

    Copy Code
    NChart chart = nChartControl1.Charts[0];
    NGraphicsPathSeries graphicsPathSeries = new NGraphicsPathSeries();
    Visual Basic
    Copy Code
    Dim chart As NChart = NChartControl1.Charts(0)
    Dim graphicsPathSeries As New NGraphicsPathSeries()
     Passing Data

    Once the series is created you can add some data in it. The shape represented by the graphics path is contained inside a NGraphicsPath object exposed from the GraphicsPath property of the series. The following code snippets show how to draw different shapes using this series:

    Copy Code

    // draw rectangle
    NGraphicsPathSeries rectangleSeries = new NGraphicsPathSeries();
    NGraphicsPath rectanglePath = new NGraphicsPath();
    rectanglePath.AddRectangle(0, 0, 1, 1);
    rectangleSeries.GraphicsPath = rectanglePath;

    // draw ellipse
    NGraphicsPathSeries ellipseSeries = new NGraphicsPathSeries();
    NGraphicsPath ellipsePath = new NGraphicsPath();
    ellipsePath.AddEllipse(0, 0, 1, 1);
    ellipseSeries.GraphicsPath = ellipsePath;

    // draw triangle
    NGraphicsPathSeries triangleSeries = new NGraphicsPathSeries();
    NGraphicsPath trianglePath = new NGraphicsPath();
    trianglePath.StartFigure(0.0, 0.0);
    trianglePath.LineTo(0.5, 1.0);
    trianglePath.LineTo(1.0, 0.0);
    triangleSeries.GraphicsPath = trianglePath;

    Visual Basic
    Copy Code

    ' draw rectangle
    Dim rectangleSeries As New NGraphicsPathSeries()
    Dim rectanglePath As New NGraphicsPath()
    rectanglePath.AddRectangle(0, 0, 1, 1)
    rectangleSeries.GraphicsPath = rectanglePath

    ' draw ellipse
    Dim ellipseSeries As New NGraphicsPathSeries
    Dim ellipsePath As New NGraphicsPath()
    ellipsePath.AddEllipse(0, 0, 1, 1)
    ellipseSeries.GraphicsPath = ellipsePath

    ' draw triangle
    Dim triangleSeries As New NGraphicsPathSeries()
    Dim trianglePath As New NGraphicsPath()
    trianglePath.StartFigure(0.0, 0.0)
    trianglePath.LineTo(0.5, 1.0)
    trianglePath.LineTo(1.0, 0.0)
    triangleSeries.GraphicsPath = trianglePath
