Placing an annotation below a series.

[Tim Rawlinson]

Hi,

I would like to place an annotation below a series in a chart. Setting the Canvas.ZIndex of the annotation in concert with that of the series seems to have no effect. I suppose I could implement the annotation (a HorizontalLineAnnotation in this case) with a new series and arrange them that way, but am hoping a nicer solution is possible. Any suggestions?

Thanks

Hi Tim, 

  

Thanks for contacting Syncfusion Support. 

  

We can achieve your requirement by overriding the OnApplyTemplate in SfChart class. Please find the code snippet below, 

  

 

protected override  void OnApplyTemplate() 

   { 

      // Canvas.ZIndexProperty is set to SeriesAnnotationCanvas 

      (GetTemplateChild("Part_SeriesAnnotationCanvas") as     

                               Canvas).SetValue(Canvas.ZIndexProperty, -1); 

       base.OnApplyTemplate(); 

    } 

  

We have prepared a demo sample for your reference and it can be downloaded from below link, 

  

Sample: Annotation_ZIndex
