How to set zoom and pan position for WPF Chart (SfChart)?

Description

This article explains how to zoom the chart area of a WPF SfChart by using the ZoomFactor and ZoomPosition properties of the chart axis.

• ZoomFactor specifies the zoom level (range of data to display), with a value between 0 and 1.
• ZoomPosition specifies the starting position of the zoomed range, also between 0 and 1.

Example scenario 

Consider a chart with 10 data points:

• When the zoom factor is set to 0.5, the chart displays 50% of the total data points — in this case, 5 out of 10.
• When the zoom position is set to 0.5, the visible range starts halfway through the data.

So, the chart displays data points from position 6 to 10.

Refer to the following code example.

C#

private void MyChart()
{
  SfChart chart=new SfChart();
  chart.PrimaryAxis=new CategoryAxis();
  chart.PrimaryAxis.ZoomPosition = 0.7;
  chart.PrimaryAxis.ZoomFactor = 0.3;
  ChartBehavior behavior= new ChartZoomPanBehavior();
}
