There was a bug in our windows installer.  Please remove the old mpl
install, grab the latest installer from the download site, and try
again.

Sorry for the trouble!

You cannot import pylab and use the FigureCanvasWx at the same time.
Please follow the lead of examples/embedding_in_wx*.py if you want to
use matplotlib in a wxpython GUI.  Using pylab at the same time as the
API is undefined and unsupported.

Thanks for the article. I read it, and I must say I disagree. This is 
the tricky part:

"Your list software is not "the author of the message", so it must not 
set or in any way meddle with the Reply-To header. "

That's what I think is wrong. When interacting with a mailing list, I 
assume I'm not interacting just with you or others. I'm receiving mails 
*from the ML* and sending mails *to the ML*. Not receiving mails from 
Alice and sending mails to Bob.

In other words: A ML, in my experience, is not different from a public 
forum. When I hit "reply" on a forum, the post goes on the forum, not on 
the mailbox of the previous poster.

I'm all for standards and for consistent behaviour and I understand the 
logic behind that article; what the authors of the RFC got wrong, in my 
opinion, it considering a mailing list just as a gigantic CC: by 
disconnected people instead than of a forum-like object. The fact both 
use the mail protocol doesn't change the fact they're different objects.

But of course that's only a philosophical problem. Thanks to the article 
I also discovered that "reply to all" sends mail both to the ML and the 
original sender (Never bothered to try, my fault). Although I find it a 
little funny.

If you happen to use Mozilla Thunderbird, there is an extension [1] that
enables Reply-To-List.
This works with a patched version of Thunderbird, which is included in
several major distros.

Hi,

Is it possible to expand the colorcycle that matplotlib uses by default?

in axes.py, class _process_plot_var_args, def _clear_color_cycle(self) It
seems that self.colors are hardcoded to be self.colors =
['b','g','r','c','m','y','k'] ... is there a way to extend this? (Without
changing the matplotlib code directly) I want to be able to extend it by ex.
dashed lines or others.. i sometimes have a large number of plots to do, and
the 7 default plot colors are not enough...

I know I could manually make a handler in my program to handle the colors
when I plot... but it would seem nicer if I could just pass a list of plot
colors to matplotlib.

Regards,
Soren

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.

Thanks,

Ryan

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.

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.

I tracked down the svn tree. The above script works ok in revision

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.

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)

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?

/Jörgen

It sure is!

For the top too you need
   subplot(2,2,1)  and  subplot(2,2,2)

For the bottom plot
   subplot(2,1,2)

They key to remember is the numrows x numcols defines the grid
and the plot number defines where the plot goes in the grid. This
is a tricky bit to wrap your head around initially but once you
get it, its a very powerful way of specifies plots with just 3
bits of info.

The list follows RFC 2822. The Reply-To header is intended to be
created by the originator of the message. List software that
overwrites the Reply-To header destroys the function it's intended
for.

There's an excellent essay on this at:

http://woozle.org/~neale/papers/reply-to-still-harmful

Mailman implements RFC 2369, which is intended to address this
issue. If you want replies to go to the list, I suggest that you
use a mail client that follows RFC 2369. If you choose to use old
software that doesn't recognize the List-Post header, please don't
complain about software that follows RFC standards.

I'm pretty sure the goal is that the eggs on SF are good to go. Please 
report it if they don't work for you.

The goal behind the pythonmac packages was that they be as easy as 
possible to install. We started all that before eggs existed (or became 
common, anyway). We may just start putting eggs on pythonmac, though 
since nothing useful happens when you double-click on them, some newbies 
have gotten confused.

That will work, though I don't think you need to uninstall it at all, 
unless you want to save a bit of disk space.

You're right -- I misread the original report.  It doesn't crash ipython 
for me either.  I just get another ipython prompt.

that's odd, it's OK for mpl to throw the exception, what shouldn't be
happening is for ipython to fully crash out.  I can't reproduce it
with SVN mpl on my box, I tried both tkagg and gtkagg as backends and
in both cases I see the exception traceback (as Michael intended by
raising the error) but I simply get back the next ipython prompt, as
usual.  I don't understand how this particular exception could crash
out ipython, since it's being raised inside regular user code...

Really, really strange...

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.

That was an oversight -- and is a good idea.  This has been added in r4586.

Thanks for finding this,

I just started playing with the CocoaAgg backend in mpl 0.90.1
w/pyobjc 1.4 and matplotlib uses the 'backend' line in the rc file
just fine. However, it doesn't seem to work well in interactive mode
using ipython 0.8.1 (control is not returned to the shell after
plotting).

Hi,

I get a complete crash dumping me in the console when there are unknown 
latex commands in a mathtext expression, this when doing interactive 
stuff in ipython -pylab.

examples:
title("$|S_{11}|$")
title("$\vbar S_{11} \vbar$")

I would also like to see an alias between | and \vert like there is in 
regular latex.

I have attached a crash report from ipython for the first case

I'm using 0.91.1, python 2.4, on win xp

Of course, I meant CocoaAgg, not -Aff.

Works fine for me now.

1) is easy:

  subplot(221)
  subplot(222)
  subplot(212)

2) requires you to use axes rather than subplot.  The syntax is
axes([left, bottom, width, height])

  ax1 = subplot(221)
  ax2 = subplot(222)
  l,b,w,h = ax1.get_position()
  ax3 = axes([0.5-w/2., 0.1, w, h])

I have the CocoaAgg backend specified in matplotlibrc in ~/.matplotlib/ as:

backend      : CocoaAgg

However, when I plot, matplotlib uses the TkAgg backend in spite of this.

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 I use the eggs, what's the best way to safely uninstall the
pythonmac package? Just delete the relevant site-packages durectory?

Thanks-
