reversing an axis

belinda_thom · March 23, 2007, 9:48pm

Hi,

I'm wondering if there's an easy way to reverse an axis in a plot.

For instance, suppose I wanted to create a plot that had its "origin" in the upper left hand corner, so that x would range from, say 0 to 1 moving right, and y would range from, say 0 to 1, moving down.

Thanks!

Using methods:

bottom, top = ax.get_ylim()
ax.set_ylim(top, bottom)

Or using pylab functions:

bottom, top = ylim()
ylim(top, bottom)
