Hi all
I have got some funny behaviour here that looks like a bug with the
spy() function. Using the latest python-matplotlib 0.87.5 package on
Ubuntu 6.10, I try:
$ ipython -pylab
from scipy import io
M = io.mmread('gd.mm')
spy(M)
M.shape
M.nnz
It looks great and I get the necessary number of
Hi,
I've found no possibility to plot my experimental data with Matplotlib.
The data are coming in the form of a list of xyz vector.
[[1,2,3],[4,5,6],...]
But Matplotlib needs 2D grid, which I can't provide.
Does anybody know a solution of such a problem?
It will be pretty nice to integrate a

Thanks for the answer, John and Jouni.
Okay, Line2D works. However, it appears to work in point (or is it pixels?)
only. It doesn't accept xycoords=figure fraction as an option. How can I
specify xy as a fraction of the figure size?
I read the transform cookbook cited by Jouni. I am afraid
Upon working with this a little further, I discover that it works only in
full-view screen mode. May be that's because xy is in pixel mode then? When I
save it to a png file and then view it, the lines are wrong.

Hi,
My plot_dates(x, y) call, while working in python 2.4, failed in python 2.4.4. x
here is dates array and y is a masked array returned by masked_values()from MA
module. After much debugging, I found that problem occurs at ma.asarray(y)
where y is the masked array with the following message:

Anyone knows which of my package (MA, numpy, ...) might be causing the

really like it to work in the newer version. Any inputs would be
appreciated.
Hello,
Thanks Mark for the link!
Exactly what I need.

Hi Eric
I tried the new spy function under Windows and it seemed to work OK. A
great leap forward, actually, given the problems I had been seeing.
Merging the spy functions was a good idea (does it work ok for very very
large, very sparse matrices?)
Trying it under Ubuntu was less
