Need both x and y axis to have the same scaling, but different values?

Apparently the correct way to display a nyquist plot (electrochemistry) is to have the same scaling on the x and y axis. Unfortunately, my x axis is up around 4-6 units and the y axis is down at 0-1. I don't want to have a ton of white space so what I want to do is change the size of the graph (same length, modify height) to make the scales the same while having different overall values.

Basically, look at how it's done correctly. (Attached image)

If you physically measure the distance between 0 and 0.2 on the y axis, it is the same as measuring a net of 0.2 units on the x axis as well.


Yes, this involves a bit of math and I'm not afraid of doing that, but I do know that igor's figure size is different than its graph size.. plot area? So is there a way to do this accurately every time?
Set the axis ranges to whatever you want and execute
ModifyGraph width={Plan,1,bottom,left}
