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:
Using Code
- Use the RadarPointSeries class to add data to a Chart control.
- Use the RadarPlotArea class to create the plot area.
- Set the location and size of the plot area.
- Add the series to the plot area.
- Create a label and legend for the chart.
- Create a chart model and add the plot area, label, and legend to the model.
- Create a chart and add the chart model to it.
- Add the chart to the Spread control.
Example
The following example demonstrates using unbound data to create a Radar chart.

RadarPointSeries series0 = new RadarPointSeries(); series0.SeriesName = "Series 0"; series0.Values.Add(1.0); series0.Values.Add(2.0); series0.Values.Add(3.0); series0.Values.Add(4.0); series0.Values.Add(5.0); RadarPointSeries series1 = new RadarPointSeries(); series1.SeriesName = "Series 1"; series1.Values.Add(2.0); series1.Values.Add(3.0); series1.Values.Add(4.0); series1.Values.Add(5.0); series1.Values.Add(6.0); RadarPlotArea plotArea = new RadarPlotArea(); plotArea.Location = new PointF(0.2f, 0.2f); plotArea.Size = new SizeF(0.6f, 0.6f); plotArea.Series.Add(series0); plotArea.Series.Add(series1); LabelArea label = new LabelArea(); label.Text = "Radar Point Chart"; label.Location = new PointF(0.5f, 0.02f); label.AlignmentX = 0.5f; label.AlignmentY = 0.0f; LegendArea legend = new LegendArea(); legend.Location = new PointF(0.98f, 0.5f); legend.AlignmentX = 1.0f; legend.AlignmentY = 0.5f; ChartModel model = new ChartModel(); model.LabelAreas.Add(label); model.LegendAreas.Add(legend); model.PlotAreas.Add(plotArea); FarPoint.Web.Spread.Chart.SpreadChart chart = new FarPoint.Web.Spread.Chart.SpreadChart(); chart.Model = model; FpSpread1.Sheets[0].Charts.Add(chart); |

Using the Chart Designer
- Select the PlotArea Collection editor.
- Click the drop-down button on the right side of the Add button (lower, left side of dialog).
- Select the RadarPlotArea option and set properties as needed.
- Select Apply and OK to close the Chart Designer.
