I guess you missed my previous reply asking for more details (I changed
the subject so that people who know more about OS X might notice it):

Hi Michael and others,
Sorry for the late answer. I am on Ubuntu 8.10. Unfortunately I have
not had time to look any more into the issue (which might very well be
an error on my part) but I will return when I have more info (I have
made a temporary fix).
I tried using valgrind-massif to reproduce
At this point, the expected dependencies are on freetype for font
rendering and Numpy and/or PIL for imaging. Nothing platform-specific.
There aren't any plans to make it usable from other languages, but
certainly a commandline interface would be trivial.

Still same with IPython 0.9.1
I will test on Win XP when I get a chance.

Selam Esmail,
I do not think there is an easy way of learning matplotlib. (Nor there is a
quick ref to make your life easier.)
I have learnt mostly by using matplotlib for my homeworks ( while everyone
using IDL or Matlab) --which is in my opinion has been best way to adapt
myself into scientific
Yes, I'm using the line2D.set_data function along with the draw_artist
(and a blit). I haven't made a line collection object since I don't
think it will speed it up by around the factor 5 that I want. I'll try
that but I still think that the ability to grab a large section of the
canvas and move it

yes == fromstring/fromfile doesn't deal with mixing \n and space (or any
other sep char), which is too bad, because this is a common use.
They could use some work in general.

Hello all,
Does anyone know of a quick reference for the various plotting
functions for pylab? I'm just getting started with this
after years of work with gnuplot.
I found this

which is very comprehensive and would be good for digging int
Thank your, but:
If the initial list is:

0.0E+00\n'
y = np.fromstring(a2,sep=' ')
>>> y
array([ 0.e+00, 1.80608883e-02, -4.95934156e+07,
0.e+00, 0.e+00])
It works perfectly.

That should be sep=' ' (a space) to make it read ASCII representations
of numbers. Otherwise it will interpret the string as binary, and if the
string length happens to be a multiple of 8, you get garbage data,
otherwise it raises the following e
Thanks, your solution is very good.

I think that not all de numbers use the same number of characters, the

join the previous column.
Your idea is quite good, but I don't know how to do it:
If I use the pylab.load code, I suppose that I have to put something i

My definition of kill is just like you said.

I will try with Ipython 0.9.1.

Good morning,
I came across a problem when building matplotlib from source. On my desktop
PC, running Ubuntu 8.10, I ran
python setup.py build
in an up-to-date svn checkout. The output (only dependencies, I don't want
to send all output, will do this if required)

Dear list fellows,
I am writing an app focused in structural geology, using wxpython and
matplotlib. To be quite honest, I'm not sure if this question should
go here or in the wxpython list (so to avoid cross-posting, I'll try
here first).
The app uses matplotlib to plot data from orientation dat
