Dear matplotlib users,
I am trying to plot a nxn symetric matrix containing zeros (in white)
and ones (in black). Quite simple, I guessed. For that I use imshow as
follows:
>>> imshow(W, cmap=cm.binary) # W is a Numpy Array with shape (100,100)
However, this does not work the way i would like (the ones appear very
blur). I would need the correct representation of a grid where the
possition 0,0 is simply the entry W[0,0] of my array.
There should be an easy way to plot this matrix, bu I cannot figure it
out.
Thanks for your help in advance.
Jose
Jose: I think you need to add interpolation='nearest' to get rid of the
blurriness.
