That's not really a mpl question, more a 'numerix' one: what does y
Hi y'all.
I have two series of data, taken over a period of time and I want to
know whether one set of data contains a signal similar to that in the
other. I believe the way to do this is to use cross-correlation(*) and
I notice that dir(pylab) now contains a function called
cross_correlate, but g
To compare two histograms you can plot a bihistogram as suggested on
http://www.itl.nist.gov/div898/handbook/eda/section3/bihistog.htm
The little function I've written to do so is below. See if it helps.

Luca,
It is a bug that appears when recent mpl is used with Numeric as opposed
to numpy or numarray. It is fixed in svn. Your possible solutions are:
1) Use numpy or numarray instead of Numeric
2) Build mpl from svn
3) Edit axes.py as indicated in this diff chunk:

Hi folks,
I'm interested in hearing some strategies for plotting two histograms on
the same plot. My goal is
to visualize and compare two distributions which have similar shapes.
My first attempt was to use alpha, but this isn't well support on PS2

and I will be incl
Try opening a python shell and type:
from pylab import *
a = [1,2,3]
a
What is a? Is it an array? Make sure you create an array by giving a
command like this:
a = array([1,2,3])

Hello All,
I've been using matplotlib for some time now, and I want to connect it

Hello all,
After some hour of fighting with, I've found that legend had some
trouble when used with errobar because errorbar return a tuple.
I know that is not a bug but I think it might be a good idea to write a
warning about in the documentation (I mean at

Is there any way to have multiple y-axes (more than two). I’m
looking to plot time series data and would like to overlay say four data sets
each with its own independent axis.
Thank you.

Hi there. I have the following versions of numpy and matplotlib
installed on Debian sarge:
In [3]: matplotlib.__version__
Out[3]: '0.87.7'
In [4]: numpy.__version__
Out[4]: '1.0.1.dev3422'
Recent installations from SVN started giving me a segmentation fault
error when I use pylab.close(). For

Can you post a short working and not-working (i.e. chopping off) example?

Apparently it was simpler than I thought:
bar (x, y, align='center', color=((0, 0, 0.5), (0, 0, 0.9), (0, 0,
0.5), (0, 0, 0.9), (0, 0, 0.5), (0, 0, 0.9), (0, 0, 0.5), (0, 0, 0.9),
(0, 0, 0.5), (0, 0, 0.9)))
does what I need.
Cheers,

I would like to plot a bar graph where subsequent bars have different
colors (i.e. alternating colors). I think this will enhance the
readability of my plot.
How can I do this?
Thanks,
