Re: [Matplotlib-users] How to change coordinate system origin
In fact, that's what I wanted to do : put the origine of my axis on le upper
left corner of my axis
with the values of y increase from top to bottom. And the tip you gave
(set_ylim) do it kindly.
Thank you again for your help.

Hi all,
I'm relatively new to matplotlib and what I'll ask to you seems to be

but I just can't figure out how to do this. I'd like to change the
origin of
my coordinate system to the upper left of my axis when I plot my
figures.
In matlab I use axis('ij') but in matplotlib I couldn't find something
similar. How will I do this ?
I am not 100% sure what you are asking and I don't have a matlab
install handy to test. If you want to plot a decreasing scale on the
y-axis, that is easy, just invert the min and max args to the ylim
ax.set_ylim(ymax, ymin)
If you want to do something more sophisticated, please describe in
detail and then I may have to tell you it is not currently supported
:-(

[Matplotlib-users] Date formatting and axes confusion
Using latest matplotlib (0.91.1) and have two about date formatting.
The following two questions are put here in attempt to get a plot of a month
with days 1-31 neatly fit onto the x axis.
1. Using DateFormatter class to format dates and am confused as
to how to set the axis properties like font size and font family of the
xtick labels. The following type of thing (leaving out the most of the
code) does not work...
daysFmt = DateFormatter('%d')
ax.xaxis.set_major_locator(days)
ax.xaxis.set_major_formatter(daysFmt)
ax.xaxis.set_minor_locator(days2)
ax.autoscale_view()
ax.set_xticklabels(xdates,family='serif', fontsize=8)
...because when I put that last line I do get the font size changed
but I lose the date formatting via DateFormatter. However if I put
only the .set_major_formatter(daysFmt) line, I get the right date
formatting...but how do I change the font?
2. I want the plot to display, for example, the month of Jan,
with *only* days 1 - 31 shown on the x axis. But if I use the
DateFormatter (leaving out the .set_xticklabels line), for the date
range given (days 1-31) it includes a couple of days on either side
of the plot (the 31st from the previous month and a day or two into
the following month). How can I get it to display only 1-31? And if I
do, will the points plotted on day 1 and day 31 be halfway cut off
by th edges of the plot? (and is there any fix for that?)
Any help is appreciated.

[Matplotlib-users] colorbar in subplots
Hello, I would like to have multiple image plots in a figure. Each plot should have its own colorbar. I tried the following: ** a = N.array(((1,2,3), (4,5,6))) P.figure(0) P.subplot(1,2,1) P.imshow(a) P.colorbar() P.subplot(1,2,2) P.imshow(a) P.colorbar() The two images display and have their own colorbar, each. However, the placement is not optimal. (see attached 'colorbar1.png') But when I try to use the Configure subplot parameters feature in the interactive figure window, only the image plots are affected and the colorbars stay as they are. When I hit the reset button in the configure subplots dialogue, the figure looks different from the way it looked, when it was generated (see attached 'colorbar2.png'). Do I have to do all the placement on my own by using axes.set_position or is there a more comfortable way using the subplot syntax?

[Matplotlib-users] wxAgg
Hello, in my matplotlibrc, I use 'backend : WXAgg'. This works fine, since I use a wxPython shell as an interactive shell with pylab. However, 'WXAgg' is not in the list of possible backends given in matplotlibrc. Is it save (also in the future) to use WXAgg, or should I try to switch to one of the other backends?

It means some other GUI toolkit is getting activated and the slowness you are seeing is resulting from a conflict between mainloops, most likely. If this is indeed the case, please run with either -dAgg or -sPS and post the full debug annoying output.

For example, say there's two people communicating: [EMAIL PROTECTED] [EMAIL PROTECTED] Usually when foo1 sends a mail to foo2, foo2 will receive a mail like this: To: [EMAIL PROTECTED] From: [EMAIL PROTECTED] CC: matplotlib-users@lists.sourceforge.net However, in one case I found that the mail was never sent to matplotlib-users. However, somehow the list.sourceforge.net mailing server intercepted it and sent it to the other person via a 'bounce' email address. How does this happen? What are the different ways one could send an email to a mailing list? Thanks, and again apologies for the off topic post. - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.

[Matplotlib-users] savefig memory useage
Hi all, I've noticed that when I save my figures using savefig the memory is not immediately released. For example, in pseudocode, times = get_times() for var_id in var_list: Plotting.figure() var_values = get_values(var_id) pylab.plot(times, values) Plotting.savefig(var+'.png', dpi=150) Plotting.close() This pseudo code loops over a list of variables, gets their values, and saves a plot for each one. The variable list has hundreds of items. If I run the code like this, the memory usage grows very quickly until python crashes. If I comment out the savefig line, or shorten the list of variables, the code completes without error. Can anyone suggest how I might write this differently so that I can process the long list of variables and save the figures? Is there any way to force the program to release memory once the figures are saved? I'm using matplotlib 0.90.1 and python 2.4 on windows XP.

Re: [Matplotlib-users] savefig memory useage
You can try running the garbage collector after each savefig. (import gc and then call gc.collect()). If you are using a GUI backend, you may want to try using the raw Agg backend instead -- there are fewer moving parts that way. There have been a number of memory leaks that have been fixed since 0.90.1. You may want to try 0.91 or a SVN checkout to see if that fixes your problem. There is additional information about memory leaks in the FAQ. I don't know if any are relevant to your particular situation: http://matplotlib.sourceforge.net/faq.html#LEAKS If none of the above helps, please send a complete but short script that reproduces the error (basing it on memleak_gui.py or memleak_hawaii.py is even more helpful), and one of the developers can look into it.

That is on purpose. If you give mathtext something that is a syntax
error, it throws an exception, showing where the syntax error occurred.
The only time mathtext gives warnings (as opposed to errors) is when a
the expression is syntactically correct but the symbols can not be found
in the currently configured font. This is to make sure that plots are
portable between matplotlib installations ... but the intention is not
to fail silently on invalid expressions.
examples:
title($|S_{11}|$)
title($\vbar S_{11} \vbar$)
I would also like to see an alias between | and \vert like there is in

That was an oversight -- and is a good idea. This has been added in r4586.
Thanks for finding this,

You're right -- I misread the original report. It doesn't crash ipython

usual. I don't understand how this particular exception could crash
out ipython, since it's being raised inside regular user code...
You're right -- I misread the original report. It doesn't crash ipython
for me either. I just get another ipython prompt.
Cheers,
Mike
Thanks Mike. I hope we can figure out what is causing the crashes but I
guess we can take this over on the ipython-list. Fernando have you tried
it on a windows machine? I'm using tkagg. Do you have any ideas on what
I could start testing to isolate the problem?

Re: [Matplotlib-users] eggs or pythonmac packages on OS X?
In article [EMAIL PROTECTED], Stephen Uhlhorn [EMAIL PROTECTED] wrote: I'm running MacPython 2.5 on Mac OS 10.5.1 and would like to update matplotlib to 0.91.1. Im using mpl 0.90.1 from the pythonmac site now. Is it better for me to wait till a pythonmac package is availabel or are the eggs on SF good to use. I would favor the SF eggs because of ease of upgrading unless there are some OS X conflicts I'm unaware of. If you use Tcl/Tk and use a current version (instead of the ancient version that is built in) then use the packages at pythonmac. I just built 0.91.1 today and it should show up there soon. Meanwhile you can get it from here: http://www.astro.washington.edu/rowen/pythoninstallers/ I hope that someday the official Mac egg version will work with 3rd party Tcl/Tk but no version I've tried has -- including 0.91.1. If I use the eggs, what's the best way to safely uninstall the pythonmac package? Just delete the relevant site-packages durectory? That's what I do, but I'm not sure it's the best way. I delete all folders whose names start with matplotlib (usually a folder named matplotlib and another named matplotlib-xxx-py2.5.egg-info) -- Russell - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.

Re: [Matplotlib-users] RuntimeError after clearing and plotting for many times
I don't know why those spaces always don't show up on the mailing list webpage. They looked fine on my gmail page. The 'test' function only has one 'for' loop. The four lines below the 'for' line are all in the loop.

Re: [Matplotlib-users] Problems with binary install of matplotlib-0.9.1 python2.4 on windows

Please give them a try and let me know if you have any more problems. Note: I just posted the files so it might take a while for them to propagate. I don't think we've purged the mscvp71 dependency -- I just installed the 91.1 exe on my system and got the same error on pylab import. I can fix it by dropping the dll into c:\windows\system32 (and I updated the install notes to this effect) but this is a pretty onerous requirement for the naive user, so if we can figure out how to remove the dll dependency or ship the dll, that would be ideal.

[Matplotlib-users] Bug in errorbar/docstring?
Hi, I think there's a bug in errorbar in trying to use asymmetric y-errorbars. According to the docstring: xerr and yerr may be any of: a rank-0, Nx1 Numpy array - symmetric errorbars +/- value an N-element list or tuple - symmetric errorbars +/- value a rank-1, Nx2 Numpy array - asymmetric errorbars -column1/+column2 However, code below that tries to use the last of these options fails, as shown in the example below. from matplotlib import pyplot as P import numpy as N x = N.linspace(-3, 3, 100) y = x**2 P.errorbar(x, y, yerr=N.c_[0.1*y, 0.2*y]) P.show() This fails with: Traceback (most recent call last): File errorbar_test.py, line 7, in module P.errorbar(x, y, yerr=N.c_[0.1*y, 0.2*y]) File /usr/lib64/python2.5/site-packages/matplotlib/pyplot.py, line 1591, in errorbar ret = gca().errorbar(*args, **kwargs) File /usr/lib64/python2.5/site-packages/matplotlib/axes.py, line 3766, in errorbar barcols.append( self.vlines(x, lower, upper, **lines_kw) ) File /usr/lib64/python2.5/site-packages/matplotlib/axes.py, line 2528, in vlines for thisx, (thisymin, thisymax) in zip(x,Y)] ValueError: too many values to unpack If I change yerr instead to (0.1*y, 0.2*y), which isn't listed as an option, I get my desired behavior. Looking at the code, it seems to come down to lines 3757-3764 in axes.py: if iterable(yerr) and len(yerr)==2 and iterable(yerr[0]) and iterable(yerr[1]): # using list comps rather than arrays to preserve units lower = [thisy-thiserr for (thisy, thiserr) in cbook.safezip(y,yerr[0])] upper = [thisy+thiserr for (thisy, thiserr) in cbook.safezip(y,yerr[1])] else: # using list comps rather than arrays to preserve units lower = [thisy-thiserr for (thisy, thiserr) in cbook.safezip(y,yerr)] upper = [thisy+thiserr for (thisy, thiserr) in cbook.safezip(y,yerr)] This code would actually seem to preclude the use of an Nx2 array, so something probably needs to be changed to bring the docstring and the code into agreement.
