Class ChartBehavior

ChartBehavior is an abstract base class for behaviors which can be added to SfChart

Inheritance

System.Object

ChartBehavior

ChartCrossHairBehavior

ChartSelectionBehavior

ChartTooltipBehavior

ChartTrackBallBehavior

ChartZoomPanBehavior

Implements

ICloneable

Namespace: Syncfusion.UI.Xaml.Charts

Assembly: Syncfusion.SfChart.UWP.dll

Syntax

public abstract class ChartBehavior : DependencyObject, ICloneable

Remarks

You can handle the SfChart events directly in Chart behavior, which will be helpful in designing the Chart application in MVVM pattern. You can add a custom behavior to the SfChart by inheriting a class from the ChartBehavior. You can also add ui elements to the Chart by making use of the top layer canvas returned from AdorningCanvas property,which can be used to place the ui elements at desired positions in SfChart.

Examples

This example, we are using ChartZoomPanBehavior.

    <syncfusion:SfChart>
        <syncfusion:SfChart.Behaviors>
            <syncfusion:ChartZoomPanBehavior/>
        </syncfusion:SfChart.Behaviors>
    </syncfusion:SfChart>

    ChartZoomPanBehavior zoomPanBehavior = new ChartZoomPanBehavior();
    chartArea.Behaviors.Add(zoomPanBehavior);
