Hello Mao,

In order to change the appearance of the first and last label of the axis you can use its LabelTemplateSelector property and based on a condition (if first or last label in your case) choose a different template. 

About the "editable" part, I am not sure what exactly you want to edit? Note that if you edit the values of the first and last labels without editing the labels between them the visualization will be incorrect. In order to make the edit meaningful in a numeric axis, you might need to also update the Minimum/Maximum and the MajorStep of the axis.

Regards,
Martin

Thank you so much, Martin. LabelTemplateSelector is doing its work. But how to know the label is the first or the end? Thank you

Hi Mao,

This depends on the set up of the axis - the minimum, maximum and the major step. You can get or set those via the Maximum, Minimum, MajorStep, ActualRange, ActualMajorStep properties. You can use the properties to set up or calculate the first/last label. 

Another approach could be to get the first and the last text blocks representing the labels in the visual tree of the axis.

Martin
