[4.6 - UI] Keep aspect ratio

I want to create HUD in my game using new UI system. It is an image in the shape of circle. I want this to be scalable, so it would fit to screen width. But I cannot make this without streching my hud, so it is no longer circular.

How to make it scalable and keep its aspect ratio?

Here are my settings:

HI,

You can try editing sprite you are using through sprite editor.
For details refer the mentioned link and look for 9-Slice Scaling :

Have you added a ReferenceResolution component?
