Re: [Matplotlib-users] plt.close() not releasing memory? Or memory leak elsewhere?
Hi All After spending all day working on this I have discovered that if I explicity change the matplotlib backend in spyder from 'Qt4Agg' to 'Agg' then my code executes as expected with no memory errors. Any ideas about this? It seems like a bug in Qt4Agg of some kind---is there somewhere I should file a bug report?

Hi Ben I am using 1.0.0. My colleague has 1.1.0 installed on his machine and is able to reproduce the same problem.

[Matplotlib-users] Fwd: [ferret_users] PyFerret (beta) documentation and release available from Ferret website
Dear all, ferret now has a pyferret module available through python. Just in case some people have used ferret before and might be interesting :) cheers, Chao -- Forwarded message -- From: Karl Smith karl.sm...@noaa.gov Date: 2012/5/22 Subject: [ferret_users] PyFerret (beta) documentation and release available from Ferret website To: ferret ferret_us...@noaa.gov For those interested in trying out PyFerret (Ferret as a Python module), or those just interested in knowing more about PyFerret, there are now documentation and download pages available on the Ferret website under the documentation tab: http://ferret.pmel.noaa.gov/Ferret/documentation/pyferret Toward the bottom part of the page is the link for the Downloads page, which gives links for pre-built binaries and for source (as gzipped tar files). Below it is a link for the Installing or Building PyFerret page, which gives step-by-step instructions for installing or building the program. There is also a link for the Known Issues page, listing changes in behavior and the most serious bugs that I am aware of. This is the latest version (0.0.8) of PyFerret which produces better graphics and supports saving images directly as PNG and PDF files. (The XGKS graphics library has been replaced with Cairo and PyQt. It still uses Plot+, so those PPL commands still work). It contains the latest released version of Ferret, and is (statically) linked with NetCDF-4.2 libraries. I still am considering it a beta version because of the bugs listed in the Known Issues page. -- Karl -- Karl M. Smith, Ph.D. JISAO Univ.

Re: [Matplotlib-users] strange behaviour with sankey diagram (maybe a bug)
lunedì 21 maggio 2012, 21:30, Kevin Davies: Hi Giovanni, Thanks for your report. It looks like in this case the dip in the large, single input caused the input label to be at the center of the diagram. You might want to try increasing the trunklength parameter. Maybe someone has ideas to make this sort of thing more automatic, but otherwise it takes some manual tweaking. Hi Kevin and thanks for replying. I've tried increasing the trunklength parameter, but i can't get the patch label in the center.

Re: [Matplotlib-users] how to remove colorbar?
Thanks Jerzy. It works fine. I may return to this topic for more discussion later. chao Jerzy Karczmarczuk-2 wrote: Benjamin Root : Colorbars are a bit tricky. They are actually a subplot axes separate from your plotting axes. And I don't think they are very easy to remove. You could do a cbar.axes.cla(), but that would still leave the ticks, tick labels and the colorbar label. I am sure that there is a way to get to what you want, but it isn't immediately obvious. Well, I tried with some success the following. Suppose the programme is: from pylab import * fig = figure() ax = fig.add_subplot(111) data = rand(250, 250) cax = ax.imshow(data) cbar = fig.colorbar(cax) show() Now, fig has two axes, the main, and the bar. The command fig.delaxes(fig.axes[1]) gets rid of the bar and the ticks. Is there anything wrong with that? Of course, I knew that fig.axes[1] was the bar, but finding it in a more complicated case should not be difficult. All the best.
