I suspect that what you are calling the alpha effect (or the blurry 
effect with 0.25) is really antialiasing, which scilab likely does not 
have. You can turn it off by adding the aa=False kwarg setting to your 
plot command.

Could you be more precise about what you mean when you say it doesn't
work? It works for me, in that the figure window that was created is
raised, plotted into, and then destroyed. Please tell us what you
expect to happen and what actually happens, as well as what backend
and matplotlib version you are using/. Best is to put your code into
a script and run it with --verbose-helpful and post the output here
along with the other requested info.

Hi all,
how to close (complitly destroy) pylab figure?
The feature is highly required for my module "openopt".
I expected something like this will work but it doesn't
from pylab import *
ion()
plot([1, 2, 3, 4], [1, 2, 3, 4])
draw()
# optional: ioff(); doesn't help as well
close('all')
Thank you in advance,
Dmitrey.

Had the same problem, solved with the setup.py attached ;)
Just modify it to fit your needs, should be a good start.
Works under vista + matplotlib 0.98.3
Cheers

I followed the thread in Sept 2007 that covers the same problem I am having, but it seems to just end without a solution.
I have attached the setup file I am using. When my application is packaged, installed and I try to get my graph I get the following message. The graph works fine while I am working from just the python script in idle.
Traceback (most recent call last):
 File "WxPyETn.py", line 4070, in GetRevGraph
 File "matplotlib\__init__.pyc", line 677, in <module>

 File "matplotlib\__init__.pyc", line 482, in _get_data_path_cached
 File "matplotlib\__init__.pyc", line 478, in _get_data_path
RuntimeError: Could not find the matplotlib data files
I really try to avoid posting and believe me, I have spent hours trying to figure a solution, but I am just plain ignorant with this and I feel there is a common solution out there someplace.
