automatically adjust x, y axis equal limit on a 1:1 ratio plot?

Dear all,

I am making a 1:1 ratio plot to compare data.
I can write a small part of code to detect which range of the x or y axis is bigger and then adjust the axis of shorter range to have the same range with the longer one.
and use set_aspect(‘equal’) method to have the same tick interval on both axises.
but is there an automatic method to do this job?

Thanks,

Chao

two lines:

ax.set_xlim(min(ax.get_xlim()+ax.get_ylim()),max(ax.get_xlim()+ax.get_ylim()))
ax.set_ylim(ax.get_xlim())
