How to enable the zooming option in OLAP Chart?

This article explains how to enable the zooming feature in a Syncfusion WPF OLAP Chart. By turning on scroll-based zooming for the chart area, users can interactively zoom in and out to analyze data more closely.

Zooming is especially useful when working with dense datasets or when users need to focus on specific data ranges.

Follow these steps to enable zooming in the WPF OLAP Chart:

Step 1: Initialize the Chart and Attach the Loaded Event

Configure the OLAP Chart and attach the Loaded event to apply zooming settings after the chart is rendered. For more information, refer this getting started documentation.

public MainWindow()
{
   InitializeComponent();
   this.olapChart.Loaded += OlapChart_Loaded;
} 

Public Sub New()
   InitializeComponent()
   AddHandler Me.olapChart.Loaded, AddressOf olapchart1_Loaded
End Sub 

Step 2: Enable Zoom on Scroll

In the Loaded event, enable zooming by setting the EnableZoomOnScroll property of the chart area to true. This allows users to zoom using the mouse scroll wheel.

void OlapChart_Loaded(object sender, RoutedEventArgs e)
{
   this.olapChart.Series[0].Area.EnableZoomOnScroll = true;
} 

Private Sub OlapChart_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
   Me.olapChart.Series(0).Area.EnableZoomOnScroll = True
End Sub 

Output
