Re: [Matplotlib-users] Polar plot - problem with negative values for radius

2011-02-17 Thread Stephan Markus
Ben, I should have mentioned that I already tried that. When I set the rscale to 'log' the plot crashes when zooming or mpl cannot even create it. Maybe some example code will help: from numpy import arange, sin, pi, cos, ones from matplotlib.backends.backend_tkagg import

Small update: I tried the very same code with MPL 1.0.1 and Python 2.5.0 on Linux 64 and Python 2.5.4 on Win32 and it runs w/o throwing any exceptions there! But: the behaviour is still not that what I expected. Still these issues are remaining: - the smallest magnitude (center magnitude in

[Matplotlib-users] Basemap-GDAL library dependency (hell)?

2011-02-17 Thread K . -Michael Aye
Dear basemap team! (I hope this is the right list for posting basemap problems? I reported the problem to the EPD list, but they don't have the capacity to test it due to the lack of GDAL installations) There's a fatal (as in crashing Python) library dependency in relation with current gdal

Essentially, I am having the same problem but installed from SVN. How do you install extra backends? I haven't seen where to do this. Although I want the TKAgg but I have installed TK/TCL. I am running 10.04 Ubuntu. Cheers, Jeff On 02/18/2011 03:37 PM, Forest Yang wrote: Hi, I am using

[Matplotlib-users] hist doesn't like 2d arrays

2011-02-17 Thread Robert Abiad
Dear Folks, I'm finding that hist has problems computing on 2d arrays. import numpy import pylab mu, sigma = 2, 0.5 v = numpy.random.normal(mu,sigma,16) pylab.hist(v, bins=1000, normed=1) This works without any problems. But if you try this:
