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,
Regards,
Devi
