HI all,
I've been using matplotlip for a while now but mainly for line plots,
scatter plots and the odd dendrogram. I recently tried plotting a
histogram (of a binomial function) and encountered a problem. So I
though I'd try the extremely simple example set on the front of the
matplotlib page and heres what I got:
Python 2.4.3 (#1, Sep 3 2009, 15:37:12)

from pylab import randn, hist
x = randn(1)
hist(x, 100)
Traceback (most recent call last):

Any idea why this isn't working? I have matplotlib v0.91.2 - will
updating to 0.99 solve the problem?
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

from pylab import randn, hist, show
x = randn(1)
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.
Kind regards,
Matthias
