Drawing Pie Return to overview

I am trying to draw no. of pie say from 0-45 degree, 45-100 degree and so on till 360. Actually, 8 Pie/Arc of different colors and different degrees to form a circle without axis.

Secondly, I have made a circle, but am viewing plots on a rectangular monitor.
So, circle of radius 5, with touch point on x axis at (5,0) and touch point on y axis at (0,5) is looking oval/ellipse.
Any way to fix this issue?

Second problem got identified. It was problem with geometry of my widget which was rectangle.
