Bug summary

2D arrays with more than about 8.000.000 columns are truncated on the right side.

Code for reproduction

import numpy as np
from matplotlib import pyplot

for length in range(6000000,10000000,500000):
    s = .5 * np.sin(np.linspace(0,6*np.pi,length))
    pyplot.plot(s)
    pyplot.imshow(s.reshape((1,len(s))),aspect='auto',cmap='seismic')
    pyplot.show()

Actual outcome

Image truncated on the right if length > 8000000.

Expected outcome

Expected same outcome independent of length.
