If the label is rotated by 45 or 90 degrees, the LabelClicked event is not firing. It seems that the "bounding box" of the label is not rotated with the text so the label is not clickable. This creates an inconsistent user experience in the app when the user expects the label to be clickable, but on the charts where label rotation is necessary to make the text more legible, the expected behavior is missing.

Greetings from Syncfusion.
We validated your query and were unable to
reproduce the reported issue at our end. We suspected that touch was not
recognized on the axis label due to its limited size when set the LabelRotationAngle. However, with the
help of the ChartAxis’s LabelStyle’s
Margin properties, you can resolve this issue as per the code snippet
