    Creating a Sunburst Chart
    In This Topic

    You can use the sunburst chart to display hierarchical data. Each hierarchy level is represented by one ring or circle in the chart. The innermost circle is the top of the hierarchy.

    The following image displays multiple rings of data.

    Sunburst Chart Example

    You can use the SunburstSeries and SunburstPlotArea classes to add a sunburst chart.

    For information about creating charts in the Spread Designer or the Chart Designer, refer to Using the Chart Control on sheet or Adding Charts.

    Using Code

    1. Add data for the chart.
    2. Add the chart.
    3. Set any additional properties such as the fill color.

    Example

    This example creates a sunburst chart.
