How to change the series color in the OLAP Chart?

This article explains how to change the series color in a Syncfusion WPF OLAP Chart. By applying a custom brush to the chart segments Interior, you can control the appearance of series and enhance the visual distinction between data points.

Customizing series colors is useful for branding, improving readability, or emphasizing specific data trends in analytical dashboards.

Follow these steps to change the series color 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 the series color customization after the chart loads. 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: Apply a Custom Color to the Series

In the Loaded event, create a SolidColorBrush and assign it to the Interior property of each chart segment across all series.

void OlapChart_Loaded(object sender, RoutedEventArgs e)
{
   SolidColorBrush solidColorBrush = new SolidColorBrush
   {
       Color = Color.FromArgb(255, 0, 0, 255) // Blue color
   };

   foreach (var series in this.olapChart.Series)
   {
       foreach (var segment in series.Segments)
       {
           segment.Interior = solidColorBrush;
       }
   }
} 

Private Sub OlapChart_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
   Dim solidColorBrush As New SolidColorBrush()
   solidColorBrush.Color = Color.FromArgb(255, 0, 0, 255)

   For Each series In Me.olapChart.Series
       For Each segment In series.Segments
           segment.Interior = solidColorBrush
       Next
   Next
End Sub
