Hi,
I've come across a bug with the savefig method when using the dpi=
argument and saving an EPS file. If you try the following code, you
will see that the frame is incomplete. Is there a way to solve this
from a user point of view?

import matplotlib
matplotlib.use('Agg')
from matplot
Hi,
A while ago, I sent an email around asking about the EPS output from
matplotlib. The following example summarizes the problem well:
import matplotlib
matplotlib.use('Agg')
from matplotlib.pyplot import *
import numpy as np
nx,ny = 10,10
image = np.random.random((nx,ny))
fig = figure(fig
Hi,
I've found that the match_original=True option in PatchCollection
causes matplotlib to crash. I have submitted two bug reports:
https://sourceforge.net/tracker/?func=detail&aid=2732455&group_id=80706&atid=560720
https://sourceforge.net/tracker/?func=detail&aid=2723527&group_id=80706&atid=56
> image.set_clim(vmin=10)
This works great - thanks!

Hello,
I am plotting a numpy array with
image = imshow(array,vmin=0,vmax=100)
If I want to change the array, I can then do
image.set_data(new_array)
and I can also update the colormap, etc. But I can't find any options
to update the vmin and vmax values. Am I missing something? What I am
l
he output is not
properly handled for PS files. Is this something that could be fixed
in future?
Thanks,
Thomas

Hello,
I am using matplotlib to create postscript and SVG files. I am
currently using imshow to show the contents of an array, but this
means that when saving vector graphics files, matplotlib resamples the
image/array onto a finer grid. What I would like, is for code such as
this:
import
ax.imshow(im,transform=tr)
>> fig.canvas.draw()

Hello,
I was wondering whether there is a way to rotate a grayscale/
colorscale when using imshow.
I have been using PGPLOT (a fortran/c plotting library) for many years
now, and the equivalent to imshow is called PGGRAY (or PGIMAG). One of
the arguments this function takes is a 6-element ar
Hi Eric,
I'm using matplotlib 0.98 (which comes with the Enthought distribution)
so that would explain why there was an issue.
Thanks for your help!

Hello,
I am using matplotlib to show an image using:
fig = figure()
ax = fig.add_subplot(111)
ax.imshow(image)
After doing this, I want to find the contours for a different image
(with different dimensions), but I do not want to interact with the
current figure or axes, I just want to retriev
