Hi Bernd,
Thanks for contacting Syncfusion Support.
We can avoid the reported problem by using LabelExtent property of axis. The axis panel will take LabelExtent value as its height when axis label size is lesser than the LabelExtent value. Please find the code snippet to set LabelExtent property of axis,
<chart:CategoryAxis LabelExtent="100" /> |
We have prepared a demo sample based on your requirement and it can be downloaded from below link,
Please find our UG documentation link to know more about LabelExtent property of axis
Regards,
Devi
