matplotlib-users Mailing List for matplotlib

The plot PDFs that matplotlib makes by default seem to be too tiny to contain
my biggest axis labels and my poor Latex stuff is chopped in half.
How fix?

Hallöchen!

Yes, it solves my problem.
Apparently, if you wait long enough, the rest of the file is indeed
written. However, with your patch, I see the whole file
immediately, which is much better in the multi-processes environment
of an Apache server. Thank you!
Tschö,
Torsten.

I wonder if we should flush a file object that was passed in... Could
you check if the following patch (committed on the trunk) helps with
your problem?

The missing parts are the xref table and the trailer, which are written
by functions called by close():
 def close(self):
 # End the content stream and write out the various deferred
 # objects
 self.endStream()
 ...
 self.writeImages()
 self.writeMarkers()
 self.writeXref()
 self.writeTrailer()
 if not self.passed_in_file_object:
 self.fh.close()
So it looks like writeMarkers() has been called but writeXref() has not.

Hallöchen!
I generate PDFs of scientific data with Matplotlib. This is done
automatically within a Web application written with Django. I
generate a PNG thumbnail, too, which always is correct, however, the
PDF is truncated in most cases.
Now I wonder whether it may be a timeout by the Web server or Django
itself. Thus, if Matplotlib takes too long (maybe due to cuncurrent
processes), it cannot write the full PDF. However, if it fails, the
truncation happens always at the same point in the file.
Here's a good PDF:
http://www-users.rwth-aachen.de/torsten.bronger/pds_okay.pdf
And this is the truncated version:
http://www-users.rwth-aachen.de/torsten.bronger/pds_truncated.pdf
Thus, this is the trailing part which is missing:
http://www-users.rwth-aachen.de/torsten.bronger/pds_missing.txt
Does anybody has an idea at which point and why Matplotlib stops
working?
Tschö,
Torsten.
