Sorry for replying so late - I was to a meeting for a few days.

As to your question: I have no idea WHY previews are needed. I only know they 
are required by some publishers if you submit a paper to them (which was my 
original reason for asking).

I posted this on scipy-user ML, then tried here and it bounced (?), so
now I'm trying again. Sigh...

OK, so I can't import pylab, but everything else (import numpy, scipy,
matplotlib and gtk) works fine.

These are installed:
scipy.__version__ returns '0.5.1'
numpy.__version__  returns '1.0rc1'
matplotlib.__version__ returns '0.87.6'

My options in setup.py for matplotlib was set to build Agg and
GTKAgg ( = 1) only, the others all = 0. If I leave them at 'auto' as
per default, matplotlib doesn't build (?). I use Ubuntu Dapper -
AMD64.

Over the weekend I managed to find the cause of the problem: Me.

I set Agg = 1, GTKAgg = 1 and GTK = 1 (the rest = 0) in setup.py and
now the pylab interface is happy. Previously GTK = 0 and it seems
pylab was looking for a shared library that's built if GTK = 1.

Hi,

The following generates a plot, but the x axis label is missing. Am I 
doing something wrong? In any case, can anyone suggest a solution or 
workaround?

This has been tested with the version of matplotlib in Debian etch 
(0.87.5).

Thanks in advance.

Kelvin,

If you are using the command line interface, try using 'xlim(a, b)' to
set the limits.

Stefan,

Thanks for the bug report--it is surprising that no one noticed this 
earlier.  It looks like Norbert's changes completely wiped out the 
setting of markerfacecolor and markeredgecolor.  I have reverted axes.py 
in svn to the 2788 revision (via revision 2799) so that it will work 
until Norbert gets a chance to add marker handling back into his patch 
and reapply it.

Hi all

The marker behaviour changed in

------------------------------------------------------------------------
r2790 | nnemec | 2006-09-29 11:46:57 +0200 (Fri, 29 Sep 2006) | 1 line

For example, try the following:

N.plot(N.random.random(1000),'r.')

Note that all the dots are blue!

These aren't covered by default params (well they use the same width
as lines.linewidth

You can customize them with

for line in ax.get_xticklines():
    line.set_linewidth(2.0)

hi,
which option is that? I know the length can be set there, but the
width?  trying e.g.
  xtick.linewidth : 1.0

Hi,

I've been working hard on www.eswap.com. It's
matplotlib powered. I would like to thank the
matplotlib community and especially John H. for making
this possible. Some of the features are:

1. See 20 (professional looking) charts per page
2. You can tag stocks with keywords
3. You can create your own sets and portfolios
4. keyboard navigation. You can use the right arrow
key and left arrow key

Scanning, Modelling and Back Testing are planned for
release early next year. Can you give it a spin and
let me know how you like it?

Thanks,

Vineet

Hi,

Is it possible in python/matplotlib to only define the x-axis range  
and have the y-axis autoscale?

I've read the docs about axis() but this seems to set the bounds on  
both the x- and y-axes.

Thanks.

Kelvin Chu

By the way,
does anyone look into the possibility of changing the feature after
drawing ?
I already ask this question a few time ago but it still in suspend.

thank you

Hi list,

I have just writen a new widget : a DragingCursor.

If anyone want and to try and use it ...

It is inspired from Cursor in widget module.

You would have to use the embedding_in_yourgui.py examples to write
your own GUI, ex examples/embedding_in_gtk.py

We have it in gtk (thank to Steve Chaplin) with 'F'.  And it would
need to be added to each backend.  Add it to your favorite backend and

George,

The problem with your attempt to use get_position() is that the aspect 
ratio does not affect the position until the apply_aspect method of the 
axes is called, which is normally when drawing occurs.  You can either 
call it yourself, or you can insert a draw command.  Here is an example 
of the first:

In [6]:pcolor(z)
Out[6]:<matplotlib.collections.PolyCollection instance at 0xb3db690c>

In [7]:gca().get_position()
Out[7]:[0.125, 0.099999999999999978, 0.77500000000000002, 
0.80000000000000004]

In [8]:gca().set_aspect(3)

In [9]:gca().get_position()
Out[9]:[0.125, 0.099999999999999978, 0.77500000000000002, 
0.80000000000000004]

In [10]:clf()

In [11]:pcolor(z)
Out[11]:<matplotlib.collections.PolyCollection instance at 0xb3dc6a6c>

In [12]:gca().get_position()
Out[12]:[0.125, 0.099999999999999978, 0.77500000000000002, 
0.80000000000000004]

In [13]:gca().set_aspect(3)

In [14]:gca().apply_aspect()

In [15]:gca().get_position()
Out[15]:
[0.31343312597200623,
  0.099999999999999978,

This bug was my fault.  I added an extra argument for rotated
ellipsis.  I fixed it in svn.  Just remove the rotation arg from the
line of interest for a fix.

Hi, all:
I added a table to my figure using 'table' function. But since this table
is very long, the user can only see part of it. Is there any easy way to
add a scroll bar to the chart so that the user can scroll it down and see
it?
Thanks
