Hi all I was wondering if anyone managed to find / install Basemap on a i386 machine running ubuntu 9.04 (Jaunty Jackalope) ... I've installed the debs through synaptic, and I've tried without success to compile Basemap (0.99), with failure at the libgeos compilation. Trying to install "old" .deb

[Matplotlib-users] Possible problem with mpl.axes.Axes.add_collection()

Hi, I have a strange problem. It seems to me it is related to mpl.axes.Axes.add_collection(), but I am too lost to be sure. I have a script for visualizing certain aspects of images, built upon many bits and pieces I found on the matplotlib example section. It basically lets me view an image fr

Re: [Matplotlib-users] log plots do not work when using base 2

I'm not able to reproduce this problem here. Can you provide a standalone script that illustrates it? Also, what version of matplotlib are you using? Mike Barnette, Daniel W wrote: > I've written a python gui to matplotlib which allows the user to plot either > cartesian, semi-log, or log-lo

Re: [Matplotlib-users] build requirements for matplotlib

The latest version I see there is 2.3.9. Is this another instance of the sourceforge file display bug that haunted matplotlib recently? Mike Nils Wagner wrote: > Hi all, > > I am confused by the build requirements for matplotlib. > I cannot find freetype 1.4 > > http://matplotlib.sourceforge.ne

Re: [Matplotlib-users] How to get ticks "out" using mpl_toolkits.axes_grid.axislines ?

Hi, Thanks for reporting this. The axes class in axes_grid toolkits uses different artists to render ticks and ticklabels. And some of the features in the original matplotlib won't work correctly, and the "tick direction" turned out to be one of them. However, I just committed a fix for this to t
