Re: [Matplotlib-users] How to reverse the direction of an axis?
In [1]:plot(arange(10)) Out[1]:[matplotlib.lines.Line2D object at 0x908ee0c] In [2]:ax = gca() In [3]:ax.set_ylim(ax.get_ylim()[::-1]) Out[3]:(9.0, 0.0) In [4]:draw() In [5]: The method in line 3 should work on new and old versions of matplotlib. The basic idea is that when axis limits are set, you specify the bottom, then the top (or the right, then the left), not min and then max.

[Matplotlib-users] How to reverse the direction of an axis?

Daehyok Shin wrote: Thanks for your help. I didn't know set_ylim can the reversed limits. I am wondering if it is not a good idea to introduce a method such as axis.set_direction(). Or, axis.set_origin(). There are Axes methods invert_xaxis() and invert_yaxis() in recent versions of mpl; I don't remember who added them or when.
