[FIXED] Why doesn't imshow show pixel values when I hover over it?

Issue

When I create an inline image in Ipython Notebook, it displays the image just fine. However, when I hover over the image, I cannot see the pixel values, that normally show up on the bottom right corner. How do I fix that? Thanks. (Below is some sample code).

import numpy as np
import matplotlib
import matplotlib.pyplot as plt
from IPython import display
%matplotlib inline  

fig, ax = plt.subplots(nrows = 1, ncols = 1, figsize=(10, 10))
for ii in xrange(10):
    im = np.random.randn(100,100)
    ax.cla()
    ax.imshow(im, interpolation='None')
    ax.set_title(ii)
    plt.show()

Solution

To see the coordinates when you hover over the plot you must NOT use inline backend for the plots. So remove the %matplotlib inline line and restart IPython with some other backend. You could use some other backend (it depends on what is available in your installation) %matplotlib gtk or%matplotlib qt.

Here is an exhaustive list of supported backends. You may want to use those that are interactive instead of inline.
