I have a script looping through and plotting 100's of figures. It runs fine, but after the first few plots, the loop considerably slows down and the memory usage keeps going up. The script is quite complicated, so can't really paste it here, but I am trying to pass figure instances around and I

I'm not an expert on this issue, and I never used Russian language. But here is my experience with unicode in matplotlib. Matplotlib's own font rendering engine (based on truetype) does support unicode rendering. But I don't think there is any support for things like a fontset. And, as far as you

Drawing box around a text is quite easy. http://matplotlib.sourceforge.net/examples/pylab_examples/fancytextbox_demo.html To place a text in a way like ticklabels, you need to use blended transform. The short example may give you some starting point. -JJ from matplotlib.transforms import blen

To change the legend font size, you may change the "legend.fontsize" in rcParams. The change will be global. If you want to change the font size of some particular legend, use the appropriate font property as the "prop" keyword. http://matplotlib.sourceforge.net/api/pyplot_api.html?highlight=legen

"imshow" sets aspect=1 unless you changed your rcparams. Unless aspect="auto", the axes position changes during the drawing time. call imshow with aspect="auto" or use set_aspect method. http://matplotlib.sourceforge.net/api/axes_api.html?highlight=aspect#matplotlib.axes.Axes.set_aspect Regards
