Graph Display showing X Ticks ito PI

[MullenJohn]

Thank you Arno and Tim!

I will be looking forward to your future graphing changes to implement PI segment labels on the Plot display.

I have used the PI/6 for the "X Tick" and 0 ... 2*PI for the "X Rng" in the Plot Setup but it would be nice if the X-Values could be displayed in terms of PI.

Cheers!
