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

WPF Chart (SfChart) allows you to zoom the chart area by using ZoomFactor and ZoomPosition properties. The ZoomFactor property defines the zooming level and the ZoomPosition property defines the zooming (scrolling) position for chart. Both values should fall between 0 and 1.

For instance, when ZoomFactor is 0.5 and ZoomPosition is also set to 0.5 for the chart with 10 data points, it shows last 5 data points in chart. Here, ZoomFactor decides no of points (5), and ZoomPosition decides range of values to display (from 6 to 10).

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();
}
