How to rotate label text in WPF OLAP Chart?

This article explains how to rotate axis label text in a Syncfusion WPF OLAP Chart. By using the LabelRotateAngle property on the primary and secondary axes, you can adjust the orientation of axis labels to improve readability when labels are long or closely spaced.

Rotating axis labels is especially useful for categorical data where horizontal space is limited.

Follow these steps to rotate axis label text in the WPF OLAP Chart:

Step 1: Configure the OLAP Data Manager

Initialize the OlapDataManager, set the OLAP report, and attach the Loaded event to apply axis customization after the chart is loaded. For more information, refer this getting started documentation

public MainWindow()
{
   InitializeComponent();

   this.olapChart.OlapDataManager =
       new Syncfusion.Olap.Manager.OlapDataManager(
       "Data Source=https://bi.syncfusion.com/olap/msmdpump.dll;" +
       "Initial Catalog=Adventure Works DW 2008 SE;");

   this.olapChart.OlapDataManager.SetCurrentReport(SampleReport());

   this.olapChart.Loaded += OlapChart_Loaded;
}

Public Sub New()
   InitializeComponent()

   Me.olapChart.OlapDataManager =
       New Syncfusion.Olap.Manager.OlapDataManager(
       "Data Source=https://bi.syncfusion.com/olap/msmdpump.dll;" &
       "Initial Catalog=Adventure Works DW 2008 SE;")

   Me.olapChart.OlapDataManager.SetCurrentReport(SampleReport())

   AddHandler Me.olapChart.Loaded, AddressOf OlapChart_Loaded
End Sub

Step 2: Rotate Axis Label Text

In the Loaded event, set the LabelRotateAngle property for both the primary and secondary axes.

void OlapChart_Loaded(object sender, RoutedEventArgs e)
{
   this.olapChart.PrimaryAxis.LabelRotateAngle = 45;
   this.olapChart.SecondaryAxis.LabelRotateAngle = 45;
}

Private Sub OlapChart_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
   Me.olapChart.PrimaryAxis.LabelRotateAngle = 45
   Me.olapChart.SecondaryAxis.LabelRotateAngle = 45
End Sub

Output
