Simple question: how can I plot something such that the y axis is "inverted"? (Increasing downwards?)
(I thought I'd better ask before fubaring my copy of mpl's transAxes, transData, bbox code and going insane in the process.)
Cheers!

Simple answer:
ymin,ymax= get(gca(),'ylim')
set(gca(),'ylim',[ymax,ymin])
Now, on to determine how to plot an image with origin='upper' with the extent going the other way...

Again, a no brainer:
(modifications to image_demo3.py)
w,h = lena.size
extent = 0,w,h,0
figure(figsize=figsize)
im = imshow(lena, origin='upper', aspect='preserve', extent=extent)
