Hi Matthias,
Thanks for using Syncfusion product.
If your intention is to set legend in outside of chart area, we suggest you to use “LegendsPlacement” property of legend to avoid legend overlaid on chart area. Please refer the below code snippet to achieve this,
[VB]
Me.ChartWebControl1.LegendsPlacement = ChartPlacement.Outside
