axis('equal')

Development matplotlib-devel

Hi,

I have submitted a bug report
1591708 pylab.axis('equal') scales wrong axis
In the attached script axis('eqaul') shrink x instead of expanding y with the result that no
datapoints are seen.

I have also submitted a simple patch
1591716 Expand y if data don't fit into x_lim
It would be great if someone could take look.
It fixes the test case, but I'm not sure if it is the right way to do it.

regards
Ulf Larsson

Ulf,

Thanks for the report. I will check it out and either apply your patch or some other fix.

Your message along with several others that were sent days ago popped up just now in my inbox. It seems like there are some strange delays in the sourceforge mailing list system.
