What you likely want to do is to make the X and Y scales have the same
span, then resize the black area of the graph to be a square. The
yellow tip-strip will help you to view the size while resizing. Of
course, the viewing rect doesn't need to be a square, but the number
range per pixel needs to be the same. If you want to do this
programmatically, you can also do it in reverse. Read the plot area
size and set the scale min and max to make things square.
