Hi,
I think the bivariate normal probability distribution function 
implementation in Matplotlib is buggy. See the example code below, and 
note that the change in the x directions and the y directions is not 
uniform as it should be.
The implementation (in mlab.py) is appended.
 Faheem.

Hi Martin,
I suggest upgrading to 0.87.3. I can run your test script and can open the 
resulting eps file. Please note, however, that you are asking for a file that 
plots 2e6 points. We have already optimized the postscript commands such that 
each marker or line requires essentially only a single line of postscript 
code (a great improvement over mpl version 0.87.2), but that still means that 
we need to write 2e6 points x 18 bytes per point ~ 36 MB (it actually ends up 
being 41MB), and postscript then has to interpret that massive file. This 
yields about a factor of 5 improvement in the size of your file, and its 
about the best we can do for postscript.
If you want a smaller file size, I suggest you convert your file to some other 
format, since most of your data points lie on top of one another, and then 
convert back to eps if you really need that format. For example, you can 
convert your 41MB eps file into a 274KB pdf file or a 6KB png file.
Finally, we dont include tiff previews in our eps files, so this is not a bug.

Hi,
When I use matplotlib for a scatter plot with both dots and connecting lines,
the exported eps file is huge, if the distances between many points are small.
I think of this as a bug, since no preview tiff is included in the generated eps
and a variety of text processing applications (including OpenOffice) crash
when I try to import the eps. Ghostscript takes forever, too. Is there anything
that I can do in order to export reasonable eps files?
I am using:
python 2.4.2
matplotlib 0.87.2
numpy 0.9.8
with Linux
The following small example illustrates the problem:
--
import pylab,numpy,random
random.seed()
x=[random.gauss(0,1)/float(i)**2 for i in xrange(1,1000000)]
X=numpy.array(x,numpy.Float32)
pylab.plot(X[1:],X[:-1],"-", c="#eeeeee")
pylab.plot(X[1:],X[:-1],"xk")
pylab.show()
--
The resulting eps file:
-rw-r----- 1 xx users 212190257 Jul 4 09:39 image.eps
Thanks a lot in advance

Arg, sorry, I have found the response by myself, I just have to use=20

Hi Jeff,
thanks for the hint, I just need to import one personal GMT file maked a ti=

ago and used in a plotting project based on GMT, which I try to convert to=

matplotlib.
Now I have a little problem to plot a basemap with subplots. Trying to use=
=20
contour_demo.py mixed with hist.py to have a map with contours and under it=
=20
an histogram of values, I can't set the colorbar else I loose the map. I=20
think I have a problem with axes but I'm not very familar with subplotting.
Have you an idea of how can I do that?

Lionel: I had included the GMT colormaps in matplotlib, but had to take 
them out because of licensing issues. If you want to put them back in, 
put the attached file in your matplotlib install directory 
<sys.prefix>/lib/python2.4/site-packages/matplotlib. Then use a text 
editor to add the following lines to _cm.py (in the same directory)
from gmt_cm import addcmaps
addcmaps(datad)
right above the line
# reverse all the colormaps.
This will give you the colormaps
GMT_gebco
GMT_globe
GMT_haxby
GMT_no_green
GMT_ocean
GMT_polar
GMT_red2green
GMT_relief
GMT_seis
GMT_wysiwyg
and the corresponding reversed colormaps (with '_r' appended to the name).

Thanks to all at MatplotLib over the years.
I've been using mpl to automate the plots for a report I've been
working on for several years. It's now been released, along with the
Python scripts, from:

It's possible. Here's how I've been doing it. 
(1) I use the gmtcolormapPylab function defined in: 
http://sourceforge.net/mailarchive/message.php?msg_id=11255878
(2) Using the above function and a GMT cpt file (e.g. 
GMT_no_green.cpt), I set a color dictionary as:
cdict = gmtcolormapPylab("GMT_no_green") 
(3) I define a colormap using:
mycmap = cm.colors.LinearSegmentedColormap("GMT_no_green",cdict,256)
(4) I apply the above using cmap=mycolormap in contourf or pcolormesh.
By the way, in case you don't know of the following site, it has an 
exhaustive selection of color palettes: http://cpt-city.org.uk/
I've also attached an example of a basemap image using a cpt from the 
above site. Masked values not defined by the colormap are shown in 
gray. 

Hi all,
Is it possible to import colormap file from GMT (.cpt) to basemap? If yes how 
can we do that?
Thanks

I am working on a plot that uses several fill() calls all of which set
some level of transparency using the "alpha" parameter.
When I added a legend to the figure the polygons made by the calls to
fill() were no longer recognizing the alpha settings.
I am using the Agg backend and the output is always generated with savefig().
Am I missing something about the configuration? How can I get
matplotlib to continue to respect the alpha setting even when calling
legend()?
Any help is appreciated!
Thanks,
Marek

I have seen that, but it doesn't help.
I have only Numeric and numpy on my system. I only need one, just 
wanted to get up to date, so tried changing from Numeric to numpy. For 
testing I rename the folder of the one I don't want to use, so py2exe 
nor matplotlib can not find it.
I don't have a real need to change, so for the moment I will stay with 
Numeric and if I don't run into other problems with matplotlib 0.87.3 I 
stay with it otherwise I will go back to the version I used before and 
upgrade when I get around to move over to wxPython Unicode.

Can not get it to work with numpy (see other thread), however using 
Numeric with the following py2exe setup.py sections looks like it works 
even using an Ansi wxPython version (my app uses a database, while I am 
planning to switch to Unicode, I don't have time for this at the moment).
The matplotlib related entries in the options section are "pytz" and 
"matplotlib.numerix" and the exclude of the wxmsg26uh_vc.dll".
# options for py2exe
options = {"py2exe": {"compressed": 1,
 "optimize": 2,
 "packages": ["encodings",
 "kinterbasdb",
 "pytz", "matplotlib.numerix",
 ],
 "excludes": ["MySQLdb", "Tkconstants", "Tkinter", 
"tcl",
 "orm.adapters.pgsql", 
"orm.adapters.mysql"
 ],
 "dll_excludes": ["tcl84.dll", "tk84.dll", 
"wxmsw26uh_vc.dll"]
 }
 }
zipfile = r"lib\library.zip"
And this is the setup section (with some stuff omitted):
setup(
 classifiers = ["Copyright:: Werner F. Bruhin",
...
 "Natural Language :: English"],
 windows = [twcb],
 #console = [twcb],
 options = options,
 zipfile = zipfile,
 data_files = [("prog\\locale\\fr\\LC_MESSAGES",
 mylocaleFR),
...
 matplotlib.get_py2exe_datafiles(),
 ("prog\\amaradata", amaradata),
 ("prog\\amaradata\\Schemata", amaraschemata),
 ]
 )
I am using py2exe 0.6.5, wxPython 2.6.3.2 and Python 2.4.
Need to do further testing with it, but the matplotlib plots (some line 
and pie charts - nothing very sophisticated) work fine.
Will give numpy another try, if I get some hints on how to overcome the 
issue reported in another thread.
Werner

Hi Werner,
I got this problem too, and I actually updated the py2exe wiki on what
to do when you see it. The problem is that there are multiple _sort
modules (_sort.pyd in numpy and others in the different numer*
packages.) Only some of them have dtype.
See the last section (seciton 5) of
http://starship.python.net/crew/theller/moin.cgi/MatPlotLib
My real solution to it was to remove all the other num* packages from
the system and just have numpy and scipy installed. This ensured that
I wasn't pulling in the other packges by accident.

I finally managed to build it without getting py2exe errors.
Needed to include package "numpy" and remove "distutils" package from 
numpy as py2exe was failing on "tests" - maybe this is not the right 
thing to do as I still get run time error when running the exe.
Here is the exception I currently get:
**** Thu Jul 06 17:43:19 2006 ****

I can run it without problem on my dev machine. The problem is when 
packaging it with py2exe, worked around this one by just excluding that 
dll, but maybe this is the cause of the problem - see other thread.

As you have found, the matplotlib binaries are built using the unicode
version of wxpython. If you are not using blitting, then you can just
go in any delete the "matplotlib/backends/_wxagg.so" (.pyd for
windows) file from the installed matplotlib module. Then the
pure-python wx backend will be used instead, and it should work fine
with both versions of wx.

I got this to work, only issue left is the py2exe problem (see other post).
Looking through the matplotlib 0.87 doc (page 13) it mentioned that one 
should use an appropriate package for the numeric package one uses, but 
I can't see see these packages.
Is it that the doc is just a bit out of date?
FYI, the section 1.2 Numerix does also not mention numpy.

Googling on it I found that it is included with wxPython Unicode.
What is needed to tell matplotlib not to use Unicode? Is this still 
possible with 0.87?

Trying to py2exe the application I get an error no such file 
"wxmsw26uh_vc.dll".
I am on:
# Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)]
# wxPython 2.6.3.2, Boa Constructor 0.4.4
Part of the changes I made inludes trying out numpy 0.8.9.
What is this dll for and where should it be? The name looks like it is 
part of wxWidget but I can't seem to find it.

Hi all,
I would like to replace the lower left corner of the attached contour 
plot by a color corresponding to zero
as defined in the colorbar. I tried to add a second contour plot but it 
doesn't work.
So how can I manage this task ?
Nils

Just tried again using GetRight download manager and did manage to 
download it. Just FYI, GetRight reported multiple disconnects due to 
busy server, but as it allows to resume this was not a problem.

I tried multiple times to download the above and/or to just view it with 
Adobe 7 but it looks like the file is corrupted.
Can anyone confirm this or is the problem on my side?

On any type of plot where the data on a given axis is strictly
positive, you should be able to set the scale to 'log'. Just make
sure that the axis limits are also strictly positive. Eg
 ax.set_xlim(0.01, 10)
 ax.set_xscale('log')
With errorbars, you have to be careful, because if the error limits on
one of your positive datapoints extend into non-positive territory,
you'll get an error with log scaling.
