angular graphs

Hello guys! 

I am trying to produce graphs like those in the JPG  (the ones on the right), to show the variation of angles as my program runs.

An expert suggested the following solution to me (please refer to the vi attached). It is really cool, but I couldn't find any way to customize it, like changing the tick interval, (what I want is 0, 15,30,45,60,75,90,... 345), changing the colour of the dial(not the needle).

I am wondering if anyone knows how to do thoses, or, if anyone has a better solution?

Thank you so much for your generous help!
