How to Create a Radar Chart with .NET MAUI?

2 mins read

A Radar chart, also known as a web chart, spider chart, or star chart, is a graphical method of displaying multi-dimensional data. To create a radar chart, we’ll use the Syncfusion® .NET MAUI Polar Charts, which allows us to create both polar and radar charts.

Configure the Syncfusion® .NET MAUI Polar Charts

Let’s configure the Syncfusion® .NET MAUI Polar chart control using this getting started documentation.
Refer to the following code example.

XAML

<chart:SfPolarChart>
   . . .
   <chart:SfPolarChart.PrimaryAxis>
       <chart:CategoryAxis/>
   </chart:SfPolarChart.PrimaryAxis>
   <chart:SfPolarChart.SecondaryAxis>
       <chart:NumericalAxis />
   </chart:SfPolarChart.SecondaryAxis>
   <chart:PolarAreaSeries ItemsSource="{Binding PlantDetails}" XBindingPath="Direction" YBindingPath="Tree" />
   <chart:PolarAreaSeries ItemsSource="{Binding PlantDetails}" XBindingPath="Direction" YBindingPath="Weed" />
   <chart:PolarAreaSeries ItemsSource="{Binding PlantDetails}" XBindingPath="Direction" YBindingPath="Flower" />
   . . .
</chart:SfPolarChart>

SfPolarChart polarChart = new SfPolarChart();
. . .
CategoryAxis primaryAxis = new CategoryAxis(); 
polarChart.PrimaryAxis = primaryAxis;
NumericalAxis secondaryAxis = new NumericalAxis(); 
polarChart.SecondaryAxis = secondaryAxis;
ViewModel viewModel = new ViewModel();

PolarAreaSeries treeSeries = new PolarAreaSeries()
{
   ItemsSource = viewModel.PlantDetails, 
   XBindingPath = "Direction", 
   YBindingPath = "Tree" 
}; 
polarChart.Series.Add(treeSeries); 

PolarAreaSeries weedSeries = new PolarAreaSeries()
{
   ItemsSource = viewModel.PlantDetails, 
   XBindingPath = "Direction", 
   YBindingPath = "Weed"
}; 
polarChart.Series.Add(weedSeries);

PolarAreaSeries flowerSeries = new PolarAreaSeries()
{
   ItemsSource = viewModel.PlantDetails, 
   XBindingPath = "Direction", 
   YBindingPath = "Flower"
}; 
polarChart.Series.Add(flowerSeries);
. . .
this.Content = polarChart;

Set the GridLineType Property
To render a Radar chart with a polygonal grid line, set the GridLineType property of the polar chart to Polygon. This configuration enables the spider-web-like grid structure used in radar charts.

XAML

<chart:SfPolarChart GridLineType="Polygon"> 
   . . .
</chart:SfPolarChart>

SfPolarChart polarChart = new SfPolarChart() 
{
   GridLineType = PolarChartGridLineType.Polygon
};
. . .
this.Content = polarChart;

The following image demonstrates how a radar chart can effectively visualize multi-dimensional data in a spider-web or star-like structure using the MAUI Polar Chart.
