Evan,
The solution you are proposing below sounds wrong to me--I am concerned
that your color bar is not corresponding to the actual levels you are
plotting on both plots. I think that what you actually need is closer
to the attached script.

Hi! I have a wxmpl.PlotPanel object with a cross-hair style cursor
(without the full screen crosshairs). When I select a rectangle w/ this
cursor it zooms in to that rectangle - great! Now, how do I get the
rectangle coordinates (preferably in data coords.) from the rectangle
selection event?

Hi guys,
I'm trying to make a specgram() for some wave samples that I have
read into 'data' using pyaudiolab's read_frames() (put into wavread())
When I do
from wavread import *
from pylab import *
from statistics import *
data, datasize, samplerate, channels = wavread("myfile.wav")

The new matshow() seems to like ticks every 4 units (or multiples of 4
for larger scales) rather than the normal, more desirable every 5 units.
Compare:
import pylab
matrix = pylab.rand(30,30)
pylab.matshow(matrix)
pylab.show()
with
import pylab
matrix = pylab.rand(30,30)
pylab.imshow(matrix)
Continuing from a previous thread re the new matshow(), adding a
colorbar() causes the matrix to shrink relative to the colorbar.
Furthermore this colorbar overlaps with the figure title.
For those like me who need a colorbar as a legend and/or who do not want
the matrix visualisation in a new

Hi,
I have to question that will help some colleagues/friends of mine to switch
to python from matlab.
1 - is there an automatic translator of code from matlab to
python/numpy/matplotlib? I believe it would be very easy to implement due
the similar syntax between the two. I could do something sim

You shouldn't have any problems making this happen, although it
Hello to all,
I've thread that apperead some time ago on this list about matlab and
teaching.
I've discovered python recently and translated part of the routine I
use in python (www.chemometrics.it).
Some of my collegue asked me if I could show them how to use python. For
matlab user I guess th

If this doesn't help, here are the generic "segfault" instructions::

If this is a 64 bit Linux machine try using numpy instead.

Hello List -
A while back, the default font changed in the matplotlibrc file.
Does anybody recall what the old default font was?
I kinda liked it better than the current font, but I don't recall what it
was.
Thanks,

hello
I have problems to plot surfaces like f(x,y)=x*y...
for example "plot_surface([1,2,3], [4,5,6], [7,8,9])" doesn't work either...
I imported the following:
from numpy import *
import pylab as p
import matplotlib.axes3d as p3
does anybody have an advice?
