Description
I'm trying to save a figure in pyplot with tight margins.
The following code works perfectly with a PDF output:
from matplotlib import pyplot as plt
plt.plot(1)
plt.savefig('test.pdf', bbox_inches='tight')
But not with PGF output
plt.savefig('test.pgf', bbox_inches='tight')
as it returns RuntimeError: Cannot get window extent w/o renderer.
I have been suggested that this may be a bug -- see question on Stackoverflow.
matplotlib 1.3.0 on Ubuntu 13.04
python -c "from matplotlib import pyplot as plt; plt.plot(1); plt.savefig('test.pgf', bbox_inches='tight');"
