Friends,
1) I want to make a plot of multiple lines. I want to make something like
./multiplot.py 1.dat 2.dat 3.dat .. n.dat
All files contain two columns and are of same length. plotfile() and load()
do not take list
I want to plot smooth line between data points (Excel like) and I can do it
with with 2 lines:
a.. Original data points as circles, for instance: plot(x, y, 'bo')
b.. Spline of these points as line: plot(xnew, ynew, 'b-')
The only problem with this is the legend - I get either 'o' or '---' but

I also noticed you used C++ constructs in your code. I think this is
not recommended.
Gregor,
Would you elaborate, please, to satisfy my curiosity? The original
file is C++, so use of C++ constructs in the patch
Hello,
So maybe a couple of images can help.

Hi,
I found a minor bug, feel free to ignore it :) . If the vertical scale
of a plot has numbers ~1E-6 the ylabel won't be visible. Example script:
#---
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(-10.0,10.0,0.1)

Like TeX, matplotlib ignores spaces in math mode and uses spacing
derived from the usual roles of the symbols. You need to use an explicit
command to add

Is it possible to create a colorbar with different scales on each side?
Example:
a temperature colorbar with celcius values on the left side and farenheit
values on the right side.
If so, how could this be done?
Please help,
Thanks,
P.Romero

A colorbar is just an axes object with some

Jeff,
I've attached a test script and my data file.
Unfortunately, the method that Im using to create the data set isn't very
portable (the data is being imported from an external program), so sending
my .npz file is the best I can do.
The gaps are about 5 pixels, and create

In regards to my previous example, the lambda function magic is unnecessary,
instead of:
gobject.idle_add(lambda iter=animate(): iter.next())
It is simply adequate to do:
gobject.idle_add(animate().next)
Which is much simpler. My apologies for over coding the solution.

Hi, P.Romero,
Please let me know if you get this working. I am trying to do the same
type of 2 axes bar chart. but I got error message.
I am using regular bar ().
the following is the email i sent a week ago. Eric, I did use the twinx(),
but it gave errors.
thanks in advance.

Hi,
sorry to bother you. This may be a trivial question for experienced
Matplotlib users. I am trying to install Matplotlib under Windows XP but
with no success. I am not familiar with Python or any of the other packages
and I've never used Matplotlib before. I followed the instructions in the
A quick but not necessarily accurate answer: Don't use Python 2.6. Use
Python 2.5. I don't think matplotlib has been 'certified' for 2.6 yet.
I suggest
(1) uninstall Python 2.6 and numpy for 2.6.
(2) Install Python 2.5 and numpy for 2.5
(3) Install matplotlib for 2.5

I'm new to matplotlib and am really enjoying using it. I'm confused by something
though:
If I plot the following linear regression it works as expected.
from pylab import *
x = range(10)
y = range(10)
m,b = polyfit(x, y, 1)
plot(x, y, 'yo', x, m*x+b, '--k')
show()
The following code produces

The following code produces an error though (only the length of the vectors
have
been changed):

x = range(11)
y = range(11)
m,b = polyfit(x, y, 1)
Hello,
I am trying convert a plot written in IDL to Python using matplotlib. So
far, I have managed to show the image on the screen equivalent to its IDL
output. The only problem that I could not figure out matching the colormaps
between them. Please see the results on this png image:

Solution: use
x = arange(11)
y = arange(11)

Thanks Eric,
That has solved my problem!
