[pylab inline backend] pylab.text() fails for large coordinates

[jordens]

pyplot.text() makes the inline backend of ipython-notebook choke. For smaller coordinates (e.g. 1e1) it works fine.

In [31]:

from matplotlib import pyplot as plt
plt.text(1e2, 0, "foo")
Out[31]:
<matplotlib.text.Text at 0x523e810>

this is git commit 83e0ea6
via the packages from https://code.launchpad.net/~jtaylor/+recipe/ipython-daily

This should probably be brought up with @matplotlib, which is where this exists (as indicated by the traceback above).

[jordens]

That depends on who determines the width and height arguments. The testcase works fine in Ipython on the text console and in a script.

[jordens]

This is due to the use of bbox_inches="tight" resizing the figure according to all text artists. I have filed matplotlib/matplotlib#883. But there might be two bugs: It appears wrong that bbox_inches="tight" resizes according to all text artists. Also ipython might just accept the size of the figure as it was specified in figsize and ask for the bounding box to be used as the size. Clipping text in the title etc is a result of the spacings not being correct. The figure should be as large as specified in figsize.

[ivanov]

This bug has two years of inactivity - I am not seeing the originally reported traceback behavior in IPython master and matplotlib's 883 was closed as "wontfix" so I'm going to go ahead and close this one as well.
