Hi, I'm using Python 2.5.2 (r252:60911, Jan 20 2010, 21:48:48) [GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from pylab import randn, hist, show >>> x = randn(10000) >>> hist(x, 100) >>> show() >>> import matplotlib >>> matplotlib.__version__ '0.91.2' and get a nice figure with a 100-bins histogram. I don't know what's going wrong with your installation.
