How can I flip the origin of a matplotlib plot to be in the upper-left corner - as opposed to the default lower-left? I'm using matplotlib.pylab.plot to produce the plot (though if there is another plotting routine that is more flexible, please let me know).
I'm looking for the equivalent of the matlab command: axis ij;
Also, I've spent a couple hours surfing matplotlib help and google but haven't come up with an answer. Some info on where I could have looked up the answer would be helpful as well.
For an image or contour plot, you can use the keyword
origin = None | 'lower' | 'upper' and for a line plot, you can set the ylimits high to low.
from pylab import * A = arange(25)/25. A = A.reshape((5,5)) figure() imshow(A, interpolation='nearest', origin='lower') figure() imshow(A, interpolation='nearest') d = arange(5) figure() plot(d) ylim(5, 0) show()
The easiest way is to use:
After you plotted the image.
Origin works only for
