[Matplotlib-users] Matplotlib hangs due to numpy.ma.power()
Hallöchen! I've had a very odd observation today: I call matplotlib 1.3.1 from Django 1.7 code running on Apache under Ubuntu 14.04. The relevant code is: figure = Figure(frameon=False, figsize=(4, 3)) canvas = FigureCanvasAgg(figure) axes = figure.add_subplot(111) ... canvas.print_figure(plot_filepath) The last command hangs. Funny enough, if I run the very same code on Django's testserver, it works. First, I thought of http://stackoverflow.com/questions/22337250 but this is not the case here. I've really assured that Agg is used, also by providing a proper config file. The oddest part is, if I replace in matplotlib/scale.py, line 136, return ma.power(10.0, a) / 10.0 with return np.power(10.0, a) / 10.0 it works! Can anybody explain this?

[Matplotlib-users] Highlighting the axes of coordinates
Hallöchen! I have a grid in my plot, but additionally I'd like to highlight the zero axes, where x=0 or y=0, e.g. by showing them in red, or with thicker lines. How is this possible?

[Matplotlib-users] EMF export doesn't work

[Matplotlib-users] Matplotlib's logo
Hallöchen! In my web app, I have an about page which contains the major components, together with the logos (Ubuntu, Apache, Django etc). http://matplotlib.sourceforge.net/_static/logo2.png is too wide, and since the name is in the list anyway, I'd like to have the circular plot itself. Do you have it separately, or the Python code which generates it? Thank you! Tschö, Torsten.

[Matplotlib-users] Invalid (trancated) PDFs in Web application
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?

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!
