OK, I have just done an "svn up" and seen that this is fixed in
http://matplotlib.svn.sourceforge.net/viewvc/matplotlib?revision=8756&view=revision

Thanks for the fix.

Sorry I have forgotten to add that you should issue a "k" key on the
plot to scale the x-axis logarithmically.

We don't currently run a Windows-based buildbot for automated tests so 
we don't tend to catch these differences on a regular basis.  The tests 
use the default fonts that ship with matplotlib, so there should be zero 
differences between Windows and other platforms (that is, at least, the 
goal).  I'll have a look at these differences next time I'm in front of 
a Windows box.

Thanks for reporting this.  This bug should now be fixed in SVN r8756 
(branch) and r8757 (trunk).

I need to generate a fairly complex chart, for which I need the ability to
specify not only subplots, but also sub-subplots.  (Our group has found such
charts useful in the past, but they were generated using horrific MATLAB
code, which we're trying to get away from as quickly as we can, not only
because the code is impenetrable, but because the MATLAB GUI is unstable,
and produces very poor results when we try to print the charts.)

I'll try to describe what I want to do in a bit more detail (it's messy).

First imagine a simple plot (just a simple X-Y line graph connecting 3-4
datapoints).  I'll call this a level-0 plot.  Now, join ~10 of these level-0
plots side-by-side (with no space between the plots).  This new aggregate is
a level-1 plot.  Next stack ~10 level-1 plots vertically, again, with no
space between them.  The resulting aggregate is a level-2 plot.  Finally
arrange ~10 of these level-2 plots side-by-side, with some spacing between
them.  The desired final product is this level-3 plot.

(In practice, the numbers of elements within each aggregate is not exactly
10.  For example, for my immediate application the numbers would be 8
level-0 plots per level-1 plot; 17 level-1 plots per level-2 plot; and 8
level-2 plots per level-3 plot.  The level-0 plots should have an aspect
ratio (H:W) of 4.  Therefore, the level-2 plots will have an aspect ratio of
almost 8.)

How can I achieve this?

Thanks!

P.S. Without knowing much about the internals of matplotlib, it seems to me
that the best way to do this would be to define a container class that can
have itself as one of the contained elements.  In this way, a containment
hierarchy of arbitrary depth could be defined.  I understand that in matplot
lib Figure objects can contain Axes objects.  Can they also contain other
Figure objects?  If not, what would be required to enable this capability?
 Any comments or suggestions on what it would take to do this would be
appreciated.

I can't reproduce this here with trunk, though I get a different crash 
in the 1.x branch (which has an easy fix).  Are there any additional 
steps required to reproduce?

Hi

I've just tried some of the source code from the Spine demos but I when I
try :

ax.spines['bottom'].set_smart_bounds(True)

I get the error:

'Spine' object has no attribute 'set_smart_bounds'


What could be the problem?

Ted

Thanks all. That fixed the problem.

Ted

Hello,

I can't log scale my axes on rev8753. It was working on a previous
check-out (possibly a month old). Using WXagg, but same as with
Qt4Agg.

Any ideas what could be wrong in the trunk? It seems to me that some
recent changes on LogLocator [
http://matplotlib.svn.sourceforge.net/viewvc/matplotlib/trunk/matplotlib/lib/matplotlib/ticker.py?view=log
]class causing this.

Good catch. Thanks for the fix.

setp(xticks, markeredgewidth=4)

Ticks are markers.

I ran the matplotlib.test() and got:
FAILED (KNOWNFAIL=90, errors=14)

I checked more carefully now. It turns out, all the differences are texts.

Most of them are very small differences: Some of them offset to right
and down a little bit. Some of them shrink a little bit. Maybe, it
results from that some fonts in Windows are difference form Linux.

But there is one test gave out very big difference:
the 'tests.test_axes.test_symlog'.
The Y axis tick labels >10 are completely lost.
Please check the attachments.

I[1]: plt.plot(range(100))
O[1]: [<matplotlib.lines.Line2D object at 0xb84f8ec>]

I[2]: xticks = getp(gca(), 'xticklines')

I[3]: xgrids = getp(gca(), 'xgridlines')

I[4]: setp(xgrids, linewidth=2)
O[4]: [None, None, None, None, None, None]

I[5]: setp(xticks, linewidth=5)
O[55]: [None, None, None, None, None, None, None, None, None, None, None, None]

This should be the solution. However xgrids are finely set to a bigger
linewidth whereas xticks doesn't change.

I[6]: xticks
O[6]: <a list of 12 Text xtickline objects>

I[6]: xgrids
O[6]: <a list of 6 Line2D xgridline objects>

I[7]: xticks[0]
O[7]: <matplotlib.lines.Line2D object at 0xb8b560c>

I[8]: xgrids[1]
O[8]: <matplotlib.lines.Line2D object at 0xb8626ec>

Interestingly xticks is returned as a list of Text objects, while each
element of this list looks like a Line2D (which really supposed to
be.)

Can you try these on your side?

Hi all; 

I'm using the excellent font Linux Libertine for writing my thesis, in
which I do my plotting in matplotlib. I would really love to be ablu to
have consistent fonts in both text and graphs - is this possible? I know
it can be loaded by \usepackage{libertine}.

Best;

Emil

Hi,

I'm wondering if there's some relatively automatic way to have the
ticklabels to come out in scientific notation for an axis that uses a
linear scale (and has a range that warrants scientific notation)?  For
example, an axis that goes from 0 to 2.E18 by default uses the labels 0,
0.5, 1.0, 1.5, 2.0 and puts 1e18 at the end of the axis.  To me this is
unappealing. 1e18 is a computer programming way to write the 10^{18} (in
LaTeX formatting).  In IDL the ticklabels are 5.0x10^{17}, 1.0x10^{18},
1.5x10^{18}, 2.0x10^{18}.  This is one instance where I think IDL gets
it right and matplotlib gets it wrong.  So, as far as I can tell, one
can give the ticklabels by hand, and so I could achieve my desired
labels that way, but it'd be nice to have a more automatic way to do it.
Searching the examples, I've come up empty so far.  I would also
advocate changing the default format for labeling axes that fall in this
category.  Do the developers have any opinions on this?

Regards,
Jon

The colormap functions seem all OK. But I got other errors irrelevant
to your update. I manually checked all images invoking errors, they
are all OK. Somehow, their file handles are not closed properly before
reopening.

Here is the test result:

>>> import PIL
>>> print PIL.__version__
>>> from PIL import Image

Hi

How do I make the tick size bigger as in thicker/bolder?

matplotlib.rc('ytick.major', size=5) makes it longer but 'not' thicker.

Yes I agree, I didn't check, I was too quick.  Thanks for this further
bug report in Friedrich Romstedt.py :-).  I forgot to push the new
branch.

The file is here online:
http://github.com/friedrichromstedt/matplotlib/blob/friedrichromstedt-get_cmap/lib/matplotlib/cm.py.
 Notice that the default branch on the repo is grayscale, when you go
in via http://github.com/friedrichromstedt/matplotlib.

I send the file attached.  Just rename the current cm.py and put in
the new one, it should work.  You said you were using svn before, so I
assumed you compiled yourself.  How did you manage to use svn without
compiling?

Can you run the test suite?

Friedrich

  Dear all,

Is there a way of avoiding the overlap between the text of the labels 
and the text of the ticks?     This is what I am getting:

     http://4c.ucc.ie/~lquesada/tmp/surface.pdf

Currently I am only doing this:

     ax.set_xlabel('Distance',fontsize=16)
     ax.set_ylabel('Size',fontsize=16)
     ax.set_zlabel('Cost',fontsize=16)

Is it also possible to give an orientation to the labels? It would be 
nicer if they are oriented parallel to the axis..
Thanks in advance for your advice!
Cheers,
Luis

The only thing I could think of is that matplotlib.matplotlib_fname does:

    fname = os.path.join( os.getcwd(), 'matplotlibrc')
    if os.path.exists(fname): return fname

So if os.path.exists is slow for directories with many files, this
could be the culprit (though it would surprise me).

Maximilian, these lines are found in matplotlib/__init__.py -- you may
want to try commenting them out and rerunning to see if this helps
your issue.

JDH

matplotlib, under normal usage, doesn't list all files in the current 
directory.  Can you provide the steps you perform before calling 
show()?  What platform are you on, and which backend are you using?

I seem to have run into this problem with wx years ago -- destroying the 
widget that fed an event from a callback causes issues.  As Chris 
suggested, the following seems to work, however:

import matplotlib.pyplot as plt
import wx

def close_figure():
     plt.close()

def onclick(event):
     if event.button==1:

While you cannot add an axes to another axes, you can set position of
an axes "relative to" another axes. The threads below show simple
approaches.

http://thread.gmane.org/gmane.comp.python.matplotlib.general/16373

http://old.nabble.com/embedding-figures-inside-another-%28coordinates%29-td22826126.html#a22832238

This may or may not work on your cases depending the complexity of your plots.
Of course, if you need more control on the axes position, you may
implement your own axes_locator.

Thanks a lot for your detailed response!
In previous posts I did give the version: '1.0.svn'. Then I installed
the latest stable version. Here is the version info:
>>> print matplotlib.__version__
1.0.0

However, the error is still there.

You could not reproduce the error in your code, because you did not
specify 'lut' when you call get_cmap
try this:
maps=[m for m in matplotlib.cm.datad if not m.endswith("_r")]
for i in maps:
	try:
		a=matplotlib.cm.get_cmap(i,256)(range(256))
	except:
		(type, value, traceback) = sys.exc_info()
		print "Problems to create %s" % (i,)
		print "The error was --> %s: %s" % (type, value)
u will reproduce the error.

Thanks very much to point out I could actually print the colormap
definition-data.
I printed all of them, and found out the colormaps invoking errors are
all tuples but not dictionaries and all other colormaps are actually
dictionaries.

A figure is a figure and an axes is an axes. They are NOT
interchangeable. The AxesGrid essentially creates a list of axes.

As you may already know, only figure class has an add_axes method. And
axes can only be added to a figure. You cannot add an axes to another
axes.

Since I have no idea what kind of special plot your code creates, I
can only suggest you to revise your code to take an axes instance as
an input, not a figure instance.

If you can, please post a simple, but complete code that demonstrate
your problem.
