Omit some of the axis

[ZKorda]

Hi,

I am trying to figure out, so far unsuccesfully, if it is possible to omit some of the axis from the plot? I.e., I have 32 variables but I would like to only show axis for the main circular degrees (0,45,90,..). I would hope my plot to look something like this https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcT9smJ1wyUqfxLpdOKpmwn57nLlg6MCCtywlQ&usqp=CAU

Thank you!
