I can get it to work with numarray. I tried briefly with numpy but I
keep getting an error about no numpy.Int8 amongst other things.

Another thought, if you want to sneak some padding in to the
ticklabels, adding some whitespace might work. Off the top of my
head, I don't know how the text layout mechanism will handle leading
and trailing whitespace. 
 xax.set_major_formatter(DateFormatter(' %a '))

I'm confused by this
 setp(xax, 'major_locator', HourLocator(byhour=(0,12)))
 # Hide every other tick; for some reason this means every _fourth_ tickline
why would you ask for ticks midnight and noon, and then hide half of
them. Why not just ask for them at noon
 xax.set_major_locator(HourLocator(byhour=(12,)))
JDH

This script _almost_ works for me:
 import datetime
 import matplotlib.numerix as nx 
 from matplotlib.dates import date2num, DateFormatter, HourLocator
 from pylab import *
 # Plot some example data
 figure()
 dmin = date2num(datetime.datetime(2006,03,29))
 plot(nx.arange(dmin, dmin+7, 0.1), cumsum(rand(70)), 'r-')
 # Label midnights and noons with the weekday
 xax = gca().xaxis
 setp(xax, 'major_formatter', DateFormatter('%a')) 
 setp(xax, 'major_locator', HourLocator(byhour=(0,12)))
 # Hide every other tick; for some reason this means every _fourth_ tickline
 setp(getp(gca(), 'xticklines')[::4], 'visible', False)
 # Hide every other label; this is really every second object in the sequence
 setp(getp(gca(), 'xticklabels')[1::2], 'visible', False)
 show()
By "almost" I mean that the script doesn't work if I run it (using
e.g. %run foo.py in ipython) but, weirdly, it does work if I paste it
into ipython. The problematic line is the one that sets some
xticklines' visibility to False: within a script it hides all tick
lines, entered in ipython it hides every other line. (This is with
Matplotlib svn 2239, IPython 0.6.15, Python 2.4.1 "official unofficial
framework build", OS X 10.4.5, WXAgg.)

Jouni is correct. Below is a small script that I have written and gets=20
the flavor of what I am aiming for, although positions are slightly off.
It would be best to be able to keep the labels centered at given=20
positions, and simply be able to move the label with something like
labs=3Dget(ax,'xticklabels')
#change position of first label
pos=3Dget(labs[0],'position')
posnew=3D(pos[1]+0.5, 0)
setp(labs[0],position=3Dposnew)
This is very similar to how ticklabels can be moved around in Matlab
but it does not do anything in pylab. Is the "non-mobility" of=20
ticklabels something that is here on purpose and cannot be changed, or=20
is it easy to modify matplotlib to allow for this?
Sincerely,
Halldor

If so, this seems less a problem of tick alignment than tick placing.
One can easily construct ticks for noon. 
 #untested
 import matplotlib.numerix as nx
 from matplotlib.dates import date2num
 dmin = date2num(datetime.datetime(2003,05,10)) # in days
 dateticks = nx.arange(dmin, dmin+7)+0.5 # 7 ticks, at noon
 xticks(dateticks, rotation=-45, ha='left')
It seems to me that you want the tick labels clearly associated with
the ticks, and you should place txhe ticks accordingly, but I can see
how there is room for argument...

I can help you walk through the diagnosis a bit
Stage 1:
Fire up a python shell
 * does import pylab cause a segfault?
If so, try importing these 1 by 1 and see where the problem is
 import matplotlib._image
 import matplotlib._transforms
 import matplotlib.ft2font
 import matplotlib.numerix
 ..maybe others but that is a good start
If not, eg you need to try and make a figure to trigger the import, we
want to enable extra verbose debugging.
Flush your build subdir, and edit setup.py to set VERBOSE = True and
recompile (capture the build to a file and post it). This will cause
the extension code to generate verbose output which may isolate the
problem. Run your test code with --verbose-debug-annoying and be
prepared for a deluge of messages.
You might want to flush ~/.matplotlib occassionaly to make sure there
is not something messing with you in the cache.
One possibility is that you are picking up multiple zlibs or libpngs
or libfreetypes, which can lead to segfaults. Try inspecting your
system to make sure you know which of these libsa are installed, which
versions, and where.
I'm putting this back on list in case your response triggers a
lightbulb in some resident OSX expert's head.
Happy hunting!

Typically I use OSX's python, but I don't want to start that debate.=20
I also build everything from source. New users should probably be
pointed to the prebuilt 2.4 framework on pythonmac. I haven't been
keeping up with the intel status though.

Are eggs accepted by pythonmac yet or they still using mpkg's exclusively?

Cocoa-agg works and has been there for the last few releases. There
are some quirks with multiple figures/windows. A toolbar has not been
implemented yet though. I still see the cocoa-agg as being sample
code on embedding matplotlib into a cocoa app. It doesn't have much
benefit in my eyes over tkagg.
When I first started the cocoa backend, I attempted it using quartz.=20
The graphics were actually really easy to get working. As I think
will be the case with Cairo, the text was the big hangup. Apple's
python interface to quartz doesn't have much of the text support
included. I think it is much better to focus on the Agg backend and
use it in gui toolkits. Otherwise, we will play this never-ending
game of trying to make the rendered results match between the
different rendering engines. Also by using the Agg backend, the
Cocoa-agg gets all the features of Agg for free. These don't have to
be re-implemented.

I think what Halldor means that it is counterintuitive to have the
weekday labels positioned at midnight. The attached example figure
shows a week's worth of data, and from a quick glance you'd imagine
that the peaks occur at night, while they really are in the afternoon. 
Aligning the labels' left-hand side with the ticks would help a
little, but not nearly as much as having the labels centered between
the ticks.

Which Python build are you using?
At the moment, there is not a Universal wxPython, and Py2App/bdist_mpkg 
is not yet working with the Universal build, so I may wait for those two 
 before I do a Universal build of MPL.
As packages built for the 2.4.1 Framework build work fine with the 
Universal build (on PPC machines) then I can probably just use what 
you've built for the moment.
By the way, what's the status of the cocoa back-end? And the Cairo 
Back-end on OS-X (and other platforms, while I'm asking)

I don't suppose you have an Intel Mac do you? That's what would really 
need testing. Or OS-X 10.3.9 -- I'm only running 10.4 on PPC.

Your second script works fine for me. I was able to switch the font in the 
postscript file, between Bitstream Vera Sans and Arial, by modifying your 
fontDict. I'm using svn mpl on linux, but I dont think anything has changed 
since 0.87.2 that would effect the results.
Are there any Mac users with a free moment to run his script?

Have you tried experimenting with the horizontalalignment property,
which accepts left|right|center ? The default is center, which often
looks wrong with rotated ticklabels
JDH

A simple plot command, which worked in 0.86, fails in 087.2:
import pylab
pylab.plot([0.0, 1.0], [0.0, 0.0])
A traceback indicates that it apparently has to do with MaxNLocator
introduced in 0.87.
There was a thread on this list 2 weeks ago started by
da...@in... concerning similar issue, but in that case y-values
were slightly diffrent. Setting pylab.ylim to something like (-1,1)
prior to calling plot(), as John Hunter suggested in that thread, does
not quite work for me in this case.
Also, the changelog to 0.87.2 mentiones that same thread and claims a
fix that "adjusts vmin and vmax if they are nearly the same, not just
if they are equal". In my simple case, they are equal, but still i
figure that it is not being treated gracefully enough.
Thanks,
Sergey

There is a "position" property on the xticklabels, but setting it
doesn't seem to have any effect. (This is on svn revision 2227.)
Perhaps you could have ticks at 12-hour intervals and hide every other
tickmark, i.e., something like
setp(getp(gca(),'xticklines')[::2],'visible',False)
Then put the weekday labels on the hidden tickmarks and empty labels
on the visible ones.

 I absolutely agree with statically linking in libpng and
freetype. This just makes sense, since it leaves no dependencies.=20
Anyone who is using GTK most likely does not care for a native mac
solution and would be using fink or darwin port's python. As of late
I usually build an egg with tk, wx, and the 3 pyarrays with the static
libs as mentioned above. This seems to be very portable. I would be
happy to test anything you create or even help in the process, but I
am guessing you'll have no problems.

Running OS X 10.3.9 matplotlib 0.87.2
If I run:
import matplotlib
matplotlib.use('PS')
from matplotlib import pylab
import Numeric
N = Numeric
PL = pylab
x = N.arrayrange(100.)
y = N.arrayrange(100.)
PL.plot(x,y**2)
PL.savefig('crap')
PL.clf()
with the default matplotlibrc setting:
font.sans-serif : Lucida Grande, Verdana, Geneva, Lucida, Bitstream 
Vera Sans, Arial, Helvetica, Avant Garde, sans-serif
I get a postscript file that I cannot view.
BUT if I change the matplotlibrc file to:
font.sans-serif : Bitstream Vera Sans
All goes well and the PS file is fine. This has been discussed on the 
list previously as an OS X font issue.
My idea was to use the following code to set the font.sans-serif 
dynamically.
However, it does not seem to work in that the ps file is not usable as 
if Lucida Grande was still the font.sans-serif setting.
There might well be something very obvious - From the font manager 
code I surmised that the 'sans-serif' entry was a list but I could be 
mistaken:
import matplotlib
matplotlib.use('PS')
from matplotlib import pylab
import Numeric
N = Numeric
PL = pylab
x = N.arrayrange(100.)
y = N.arrayrange(100.)
fontDict = {'family':'sans-serif',
 'style': 'normal',
 'variant':'normal',
 'weight': 'medium',
 'stretch':'normal',
 'size': 12.0,
 'sans-serif':['Bitstream Vera Sans']}
PL.rc('font',**fontDict)
PL.plot(x,y**2)
PL.savefig('crap')
PL.clf()

Hi all,
I'm hoping to contribute to the effort to of providing pre-built 
packages for the new Universal Build of Python 2.4.3 for OS-X. They'll 
go up on pythonmac.org eventually. I'd like to get some consensus for 
what the MPL package should look like.
In the past, I've done it this way:
libpng and libfreetype statically linked
Support for tk and wx.
No support for GTK.
How does this look for folks?
Does anyone use PyGTK with the Framework build of Python (rather than 
darwinports or fink)? If so, if someone can either build a package for 
it or tell me how, I could support that as well.
Charlie: I know you've been building packages -- how are you doing it? 
for what Python? Maybe I don't have anything to do.

Have you seen examples/fill_between.py?

Hi All,
I have seen the example fill_demo.py where the pylab.fill method is
used to fill in the curve for a function. However, this demo fills
from the function value to the 0-line of the y-axis. What I want to
do is fill BETWEEN 2 lines (i.e. have the baseline be a curve instead
of y=3D0). Is this possible with the pylab.fill method?
Cheers,
Julius Lucks

I am in the midst of battling the OS X postscript font idiosyncrasies.
I wish to switch to:
 font.sans-serif : Bitstream Vera Sans
so that I can produce usable postscript files. This works fine if I 
edit the matplotlibrc file and run the code.
BUT I figured it would be better to do this in the code, since I only 
want this for the PS backend.
I thought that the following should produce the same result as editing 
the matplotlibrc file but it apparently does not.
fontDict = {'family':'sans-serif',
 'style': 'normal',
 'variant':'normal',
 'weight': 'medium',
 'stretch':'normal',
 'size': 12.0,
 'sans-serif':['Bitstream Vera Sans']}
pylab.rc('font',**fontDict)
What (probably obvious) am I missing?
By the way pylab.rc('text',usetex = True) works fine for me to yield 
good PS.
