Is there an option in the calculator to make the axis proportional to each other? I want graphs of circles to look like actual circles instead of eggs that are stretched in the x-axis. In Matlab the command would be "axis equal".

I have already tried using Google, looking through settings, the options at the "window"- and "zoom"-buttons, the last thing that I tried was watching the video about "Basic Graphing" by KermMartian, to no avail.

I'm using system version 5.4.0.0034
