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

Hello,
So maybe a couple of images can help.

The easiest solution would be to use a proxy(?) artist.
For example,
l1, = plot(x, y, "bo") # original points
l2, = plot(xnew, ynew, "b-") # interpolated line
l3, = plot(x, y, "bo-") # just for the legend
l3.remove() # remove the line from the axes so that it is not drawn.
legend([ll3
There are a few ways to do that depending on exactly what you want.
From your script, you may just clip your image.
im = imshow(Z, extent=(-1, 1, -1, 1))
im.set_clip_path(Circle((0,0),1, transform=ax.transData))
(Note the use of extent keyword in imshow)
Or,
You can use polar coordinate with p
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)
plt.plot(x,1E-6*np.si

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 space.

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

I don't know who I should notify about this, but I've found a fix for simple
animation. If one uses the code found here:
http://matplotlib.sourceforge.net/examples/animation/simple_anim_gtk.html it
works okay, but if you try to move the window it freezes, and you can't use
anything on the toolb

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
Mat
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

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:

Thanks Eric,
That has solved my problem!
