How to Rotate Data Labels in .NET MAUI CartesianChart?

This article guides you on how to rotate data labels in a .NET MAUI SfCartesianChart. Data labels can be rotated by setting the angle (in degrees) using the Angle property of ChartDataLabelStyle.

Step 1:

Begin by initializing the SfCartesianChart following the guidelines in documentation.

Step 2:

The ShowDataLabels property of the series is used to enable the data labels. Utilize the Angle property of type double, available in the ChartDataLabelStyle, to rotate the data labels in the chart. Refer to the following code sample for reference:

[XAML]

 <chart:SfCartesianChart>
 ..
     <chart:ColumnSeries ItemsSource="{Binding Data}"
                         XBindingPath="Year" 
                         YBindingPath="SalesRate"
                         ShowDataLabels="True">
       <chart:ColumnSeries.DataLabelSettings>
           <chart:CartesianDataLabelSettings>
               <chart:CartesianDataLabelSettings.LabelStyle>
                   <chart:ChartDataLabelStyle Angle="90"/>
               </chart:CartesianDataLabelSettings.LabelStyle>
           </chart:CartesianDataLabelSettings>
       </chart:ColumnSeries.DataLabelSettings>
   </chart:ColumnSeries>
</chart:SfCartesianChart>

[C#]

  SfCartesianChart chart = new SfCartesianChart();
 ...
  var series = new ColumnSeries
  {
      ItemsSource = new ViewModel().Data,
      XBindingPath = "Year",
      YBindingPath = "SalesRate",
      ShowDataLabels = true,
  };

 series.DataLabelSettings = new CartesianDataLabelSettings();
 series.DataLabelSettings.LabelStyle = new ChartDataLabelStyle()
  {
      Angle = 90,
  };

  chart.Series.Add(series);
  this.Content = chart;
