Radar Line

In This Topic

A Radar Line chart plots the values of each category along a separate axis that radiates from the center of the chart and ends on the outer ring. A line connects all the values from a series. The following figure displays a Radar Line chart.

Figure 1.

Creating a Radar Line Series

Radar Line series are represented by the NRadarLineSeries type. An instance of this type must be added to the series collection of a Radar Chart (NRadarChart object).

C#	Copy Code
nChartControl1.Panels.Clear(); // clear the Charts collection and create a new radar chart NRadarChart radarChart = new NRadarChart(); nChartControl1.Panels.Add(radarChart); // add radar axis for each radar ray radarChart.Axes.Add(new NRadarAxis()); radarChart.Axes.Add(new NRadarAxis()); radarChart.Axes.Add(new NRadarAxis()); // add a radar area series to the chart NRadarLineSeries radarLine = new NRadarLineSeries(); radarLine.Values.Add(10); radarLine.Values.Add(20); radarLine.Values.Add(30); radarChart.Series.Add(radarLine);

Copy Code

nChartControl1.Panels.Clear();
// clear the Charts collection and create a new radar chart
NRadarChart radarChart = new NRadarChart();
nChartControl1.Panels.Add(radarChart);
// add radar axis for each radar ray
radarChart.Axes.Add(new NRadarAxis());
radarChart.Axes.Add(new NRadarAxis());
radarChart.Axes.Add(new NRadarAxis());
// add a radar area series to the chart
NRadarLineSeries radarLine = new NRadarLineSeries();
radarLine.Values.Add(10);
radarLine.Values.Add(20);
radarLine.Values.Add(30);
radarChart.Series.Add(radarLine);

Visual Basic	Copy Code
NChartControl1.Panels.Clear() ' clear the Charts collection and create a new radar chart Dim radarChart As New NRadarChart NChartControl1.Panels.Add(radarChart) ' add radar axis for each radar ray radarChart.Axes.Add(New NRadarAxis()) radarChart.Axes.Add(New NRadarAxis()) radarChart.Axes.Add(New NRadarAxis()) ' add a radar area series to the chart Dim radarLine As New NRadarLineSeries radarLine.Values.Add(10) radarLine.Values.Add(20) radarLine.Values.Add(30) radarChart.Series.Add(radarLine)

Visual Basic

Copy Code

NChartControl1.Panels.Clear()
' clear the Charts collection and create a new radar chart
Dim radarChart As New NRadarChart
NChartControl1.Panels.Add(radarChart)
' add radar axis for each radar ray
radarChart.Axes.Add(New NRadarAxis())
radarChart.Axes.Add(New NRadarAxis())
radarChart.Axes.Add(New NRadarAxis())
' add a radar area series to the chart
Dim radarLine As New NRadarLineSeries
radarLine.Values.Add(10)
radarLine.Values.Add(20)
radarLine.Values.Add(30)
radarChart.Series.Add(radarLine)

Passing Data

Once the Radar Line series is created you can add some data in it. Radar Line series use the Values data series for the data point values. You can either manipulate directly this data series, or use the data point interface to add data. Please refer to the Working with Data Points topic for more information.
