How to improve performance while zooming by using scrollbar in WPF Chart (SfChart)?

To enable scrollbar visibility in the WPF Chart (SfChart), set the EnableScrollBar property to true for both the primary and secondary axes. For enhanced performance during zooming operations, you should set DeferredScrolling to true on both axes.

In the following code example, a FastLineBitmapSeries is used, as it provides superior performance when zooming in on large datasets.

XAML

<!--DeferredScroling property is used to improve performance when large amount of data is zoomed-->
<Syncfusion:SfChart.PrimaryAxis>
      <Syncfusion:CategoryAxis DeferredScrolling="True"  
                               EnableScrollBar="True"/>
</Syncfusion:SfChart.PrimaryAxis>
<Syncfusion:SfChart.SecondaryAxis>
      <Syncfusion:NumericalAxis EnableScrollBar="True" 
                                DeferredScrolling="True"/>
</Syncfusion:SfChart.SecondaryAxis>
