Creating a Radar Plot
In This Topic
You can create a radar plot chart using code or the designer. The following image shows a Radar point type chart.
For details on the API, see the RadarPlotArea class. The following classes are also available when creating Radar plot type charts:
- point Chart
RadarPointSeries - Line Chart
RadarLineSeries - Area Chart
RadarAreaSeries
In addition, value axes such as ruler lines, memory, and scale labels are set using the following classes.
Using Code
- Create a RadarPointSeries object that represents the data series of the radar (marker) chart and add the data.
- Create a RadarPlotArea object that represents the plot area and set its position and size.
- Add a data series to the plot area.
- Create labels and legend areas.
- Create a ChartModel object and add plot areas, labels, and legend areas.
- Assign a chart model to the chart.
Example
The following example demonstrates creating a Radar chart.

Using the Chart designer
- Run Chart Designer.
- Select the target Chart Model from the tree menu on the left.
- Open the Plot Area Collection Editor from PlotAreas in the Other section of the property list on the right.
- Click the drop-down button to the right of the Add button.
- Select and add the RadarPlotArea and set each property as required.
For information on starting Chart Designer, refer to Chart Designer in the SPREAD Designer Guide.
