Set Aspect Ratio of CurveDialog

[Brett Ables]

It seems there is no way to control the aspect ratio of a CurveWidget - is
that true?

I'd like to be able to set a fixed aspect ratio of 1. I'm plotting the
shapes of physical objects, so having them displayed in the correct scale
is vital.

I see that ImageWidget has a bunch of functions related to aspect ratio
like set_aspect_ratio, get_aspect_ratio, etc, but I can't find anything
equivalent for curves.

Would it be possible to make a workaround by getting the current axes
bounds and resetting them to be an aspect of 1.0? I've tried doing
it programmatically, but I think the problem is that if I try to set the
aspect before the plot as rendered, the current x and y bounds are still 0
or something.

Any thoughts?

Well, ImageWidget inherits from CurveWidget, so you could try rendering
your curve plot items using an ImageWidget which provides control over the
aspect ratio. I haven't tested it. But I guess it should work.
