Can I set each label in RadCartesianChart?

[Johnny]

chart[i].HorizontalAxis= new LinearAxis() {  LabelInterval = 10  };

Use LabelInterval can control  regular pattern of label.

If I only want to show the last label? (attachment1)
if I wnat to show the  Irregular label? (attachment2)

Hello Johnny,

I think you should take advantage of the LabelTemplateSelector to achieve this scenario. You can check the value in the SelectTemplate method and decide whether or not you want to return a regular or an empty data template.
