Associate Annotation With Individual Series

[Dean SanFilippo]

Hi,

Is there any way to associate an annotation with a specific series so that the annotations are displayed/hidden when the individual series on the legend is selected/unselected?

Thank you,

Dean

Hi Dean,

Yes, you can associate the visibility of an annotation with a specific series by binding the IsSeriesVisible property of the series to the Visibility property of the annotation. This way, the annotation will be displayed or hidden when you toggle the visibility of the associated series in the legend. Here is a code snippet to demonstrate this:

<Grid>

    <chart:SfChart>

 

        <chart:SfChart.Legend>

            <chart:ChartLegend ToggleSeriesVisibility="True"/>

        </chart:SfChart.Legend>

 

        <chart:SfChart.Annotations>

            <chart:VerticalLineAnnotation Visibility="{Binding IsSeriesVisible,ElementName=lineSeries}"/>

        </chart:SfChart.Annotations>

 

        <chart:LineSeries IsSeriesVisible="False" x:Name="lineSeries" />

        <chart:LineSeries IsSeriesVisible="True" x:Name="lineSeries2" />

 

    </chart:SfChart>

</Grid>

Output:
