Re: [Matplotlib-users] matplotlib and py2exe
Hi Emmanuel,
Maybe your problem has to do with your "enthought" build of wxPython. I
use standard builds from wxPython site.

You get two copies of matplotlibdata as you kept both of the two above
lines active. You need to use the first one of you use the py2exe
option to create a library.zip which I put into a sub-folder called
'lib' in the sample setup.py file.

You are also using an 'egg'. I seem to recall that py2exe does not yet
really support that, but you might want to check on the py2exe list
(e.g. on the gmane mirror of it at

Re: [Matplotlib-users] Program hangs when I call pylab.show()
I assume you mean the first example, the wire frame
(see below). It works for me. No problems. When
pylab (matplotlib) plots it does so in a window
associated with a Python process that is separate from
the terminal (I assume you are using a terminal). You
might need to bring that process window to the
foreground.
Here's the code that worked for me:
from numpy import *
import pylab as p
import matplotlib.axes3d as p3
# u and v are parametric variables.
# u is an array from 0 to 2*pi, with 100 elements
u=r_[0:2*pi:100j]
# v is an array from 0 to 2*pi, with 100 elements
v=r_[0:pi:100j]
# x, y, and z are the coordinates of the points for
plotting
# each is arranged in a 100x100 array
x=10*outer(cos(u),sin(v))
y=10*outer(sin(u),sin(v))
z=10*outer(ones(size(u)),cos(v))
fig=p.figure()
ax = p3.Axes3D(fig)
ax.plot_wireframe(x,y,z)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
p.show()

If we wanted MPL to be full featured for GUI stuff -- we have to either pick on GUI toolkit, or essentially write full GUI toolkit -- and there really are enough already! Maybe Matlab's gotten better than it was in my day (version 5), but while simple GUI stuff was doable -- it was really pretty limited and painful. If you want a GUI -- use a GUI toolkit. Once you get over the learning curve, you really will be happier -- so I think John has made the right choice limiting MPL's built-in capabilities. > I intend to write a more serious > app using Python that needs a GUI (an audio file viewer and editor to be > used for my music perception research).

You can't. If you want Mac-only then you should certainly check out PyObjC -- and use InterfaceBuilder with it.

Re: [Matplotlib-users] Program hangs when I call pylab.show()
Hi,
The examples worked for me too, and I am using IDLE on Windows. And
isn't the program supposed to return control to the terminal even if
the Graph Window is in the background?
There may be something wrong. Can you post the exact code that you are
trying to run and the version numbers? I am not an expert, but it may
help.

John,
Thanks for the explanation. I made another change. It should still
support both formats, but with only a single try/except to decide which
format to use, so the performance penalty should be negligible. The
advantage is that we won't get questions (as we have at least once)
about "why doesn't finance_demo.py work?"
Here are the relevant lines from finance.py (slightly mangled by the
mailer, as usual):
datefmt = None
for line in lines[1:]:
vals = line.split(',')
if len(vals)!=7: continue
datestr = vals[0]
if datefmt is None:
try:
datefmt = '%Y-%m-%d'
dt = datetime.date(*time.strptime(datestr, datefmt)[:3])
except ValueError:
datefmt = '%d-%b-%y' # Old Yahoo--cached file?
dt = datetime.date(*time.strptime(datestr, datefmt)[:3])
d = date2num(dt)

Re: [Matplotlib-users] Program hangs when I call pylab.show()
I get this behaviour as well, but only on first usage of show(). However, after that there is no problem. The default is to start off with interactive mode off, but the first usage of show() turns it on. So I would guess that the problem is that with interactive mode turned off, the figure window is not returning.

The 3D window takes about 2 seconds to plot, and whan the user rotates the image, it only updates at about 1fps. Gnuplot does the plot pretty much instantaneously and rotates and zooms smoothly, so that's probably going to be the deciding factor... -- Grant Edwards grante Yow! Is it 1974? What's at for SUPPER?
