Ho I wasn't aware of an mpl-dev mailing list. Sorry.
py3 is already ok with python3  *and* python2 isn't it?

Maybe the website should advertise a bit on the needs to test the py3 
branch.
Users used to compile mpl from git should be able to produce valuable 
technical feedback, shoudn't they?

I've been seeing weird behaviour with using a colorbar() and adjusting
the plot extents, either interactively in the GUI or through
figure.subplots_adjust. If I adjust the axes after drawing the
colorbar, it is placed incorrectly. This seems to happen independently
of the backends that I have and even continues through to the written
file with figure.save_fig. I'm using matplotlib.__version__ = 1.1.0,
with a git checkout that I recently updated.

I have included a short test .py that shows the problem, and two
images that it produces:
- Adjusting after drawing the plot: http://ndevenish.com/images/post_adjust.png
- Adjusting before drawing the plot: http://ndevenish.com/images/pre_adjust.png

Is there a way I can avoid or correct this behaviour? It certainly
seems erroneous that using the figure GUI to adjust plot bounds
doesn't work, and is an especially nice way of tweaking for final
plots.

Thanks,

Nick

Are there features already in master that should be supported by
<python-2.6? If so, I think we should consider releasing 1.1.0 and
making a 1.1.x maintenance branch before merging the py3 stuff back
into master. Then mpl-1.2 could be the first to support py3.

Should we move this discussion to the mpl-dev mailing list?

This was recently discussed in the thread "v1.0.x branch seems confused."

I (believe) the consensus was to get out another v1.0.x maintenance 
release out in the near future (which would not support py3k, but would 
still support Python 2.4), and then merge the py3 branch into master so 
it starts to get some more testing before making the next major release.

I'm just today merging master into py3 so that when we are ready to do 
the merge the other way most of the hard work will have already been done.

Hi,

It looks like the matplotlib-py3 branch is worknig well both with 
python2.X and python3.X.
Is there a plan to merge the changes from matplotlib-py3 into the 
default trunk anytime soon?

Hello,
i have some problems formatting my plot with dates on the x-axis.

My time array contains datetime objects with year,month,day,hour,minute. 
Matplotlib shows hour, minute, second and the timezone. I want only hour and 
minute! I set my timezone in the matplotlibrc to 'UTC', but mpl shows still 
CEST.


Here is a code snippet:

fig = figure(figsize=(8,7))
ax = fig.add_subplot(211)
xticks(visible=False)
ax.plot(...)
bx.twinx()
bx.plot(...)
cx = fig.add_subplot(211,sharex=ax)
cx.plot(...)
dx = cx.twinx()
dx.plot(...)

I tried:

from matplotlib.dates import DateFormatter
fmt = DateFormatter('%H:%M')
cx.xaxis.set_major_formatter(fmt)
and
ax.xaxis.set_major_formatter(fmt)

but this doesn't change anything!

I hope someone can help me.

Greeting

MQ
