I am using Python 2.7 and matplotlib to create a simple plot window on Ubuntu 12.10.

When plt.plot() is called, an empty windows comes up, but closes instantaneously, without displaying any figure inside it, only a grey background. However, if I try with plt.savefig('name') the correct figure is saved.

Also, I guess it is important to mention that I do have plt.show() at the end. A plot window does appear, it's just blank.

Some code:

def plot(self):
        # Plotting the track
        coordinates = np.genfromtxt(self.data, delimiter=self.coord_delimiter)

        plt.plot(coordinates[:, 0:1], coordinates[:, 1:2], linestyle='-', color=self.track_color, linewidth='2')

        plt.savefig('m1') # This works
        plt.show()

What could cause the plot window to be blank, but the saved image to be correct?

do you have plt.show() at the end? –  NKN Dec 8 '13 at 23:10
    
@NKN: yes, I do. My mistake for not mentioning it in the post. I do have plt.show(). This is why a window does come up, the problem is that it is blank. –  cgf Dec 8 '13 at 23:13
    
can you provide some code? –  NKN Dec 8 '13 at 23:14
    
@NKN: just edited my original post. Just not sure about how useful it's going to be. –  cgf Dec 8 '13 at 23:20

Are you running this as as script, or interactively? –  tcaswell Dec 9 '13 at 0:31

It's been a while now, but if I remember correctly, I think I used:

plt.block(True);

in order to get it fixed.
