matplotlib-users Mailing List for matplotlib (Page 11)

hi all,
suppose i have am plotting several lines using 'plot', some are dashed
(using '--') and some are ordinary solid lines. i am plotting several solid
and several dashed lines, all in different colors, as in:
for n in num_lines:
 # plot dashed line
 plot(line_x[n], line_y[n], '--', color=line_color[n], label="line %d"
%(n))
 # plot ordinary line in different color
 plot(line_x[n], line_y[n], color=other_line_color[n], label="line %d"
%(n))
 ...
If i plot n lines, i don't want the legend to show n-items, giving a
separate key for each line. rather, i want it to display a legend containing
a label for the dashed lines and a label for the solid lines, as in:
Legend:
[-- line of type A
 - line of type B]
so 2 entries rather than as many entries as i have lines. how can i do this?
finally, how can i make it so the legend does not interfere with the plot?
right now the lines appear "behind" the legend. it'd be great if the legend
could be made to be in the background of the line (i.e. be transparent.)
thank you.

Hello Users,
I need some help with formatting a legend for a stacked bar graph. Each bar
is segmented into ~35 categories so my legend ends up being a long mess
overlapping my plot. How can I position my legend outside of the plot and
reduce the spacing and fontsize for the text?
Thanks,
- Chuck

This is caused by an interaction between antialiasing and filled areas 
with perfectly aligned edges. Both Agg and Cairo suffer from this 
"problem". There has been a discussion on the devel a few times about 
ways around it, none of which have really panned out, if I recall 
correctly. Though this isn't a regression, as far as I can tell. 
0.98.5.x produces the same lines as SVN (at least for me).
Sorry I don't have an easy answer to this.

One work around is to call
 self.figure.subplots_adjust()
after geometry changed. After this call, the twinx-ed axes will have
the same axes position as the original one.
Another option is to use mpl_toolkits.axes_grid
(http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html#parasiteaxes).
But the previous solution seems to be much easier for you.

Hello,
I have a little of the topic question. We have a project (
http://sourceforge.net/projects/adpaa/) setup in SF using the CVS.
There when I look at the code submit logs: for instance:
gsever <http://sourceforge.net/users/gsever> committed patchset
219<http://adpaa.cvs.sourceforge.net/viewvc/adpaa/src/>of module src
to the Airborne
Data Processing and Analysis <http://sourceforge.net/projects/adpaa/> CVS
when I click the patchset link it transfers me into the main src folder not
directly to the modified file as in matplotlib's :
heeres <http://sourceforge.net/users/heeres> committed revision
7260<http://matplotlib.svn.sourceforge.net/viewvc/matplotlib?view=rev&revision=7260>to
the
matplotlib <http://sourceforge.net/projects/matplotlib/> SVN repository,
changing 1 files
here revision nicely transfers me into the right place. So that I can follow
changes easily.
Is this an SVN feature or should we enable something somewhere in the
project proterties?
Thank.

twinx() does not return an axes that contains the change_geometry
method. How then can I do the equivalent on this axes? Calling twinx()
again on the original axes after change_geometry() has been called
does not do the trick. Thanks.

It looks like this bug has been fixed on the SVN trunk. Unfortunately, 
these changes were pretty major surgery, so they don't easily apply to 
0.98.5.x. Unfortunately, for the time being, it looks like you'll need 
to wait until the next release, or compile matplotlib from SVN 
yourself. I haven't heard any concrete plans about the next release yet.
Cheers,
Mike

You might be running into one of the path simplification bugs in the 
0.98.x series. Have you tried with the rcParam path.simplify turned 
off? If you can sent me a self contained script and data off-list, I 
can test this against the SVN version to see if this has already been 
addressed.
Cheers,
Mike

Whenever I try to use autofmt_xdate() on a Figure(), dates on x axis
disappear...I guess this is related with something concerning font
management...
Anyone experienced this kind of issues?
I use most recent versions of matplotlib, numpy, gtk2, pygtk on a Python 2.5
platform (installed via binaries on a window xp machine).

Hi all,
I tried this again with a clean checkout from svn:
svn co
https://matplotlib.svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlibmatplotlib
(checks out revision 7262)
cd matplotlib/release/osx/
unset PKG_CONFIG_PATH
make fetch_deps
cd bdist_mpkg-0.4.3
sudo python setup.py install
cd ..
make dependencies
cd ../..
python setup.py sdist
mv dist/matplotlib-0.98.6svn.tar.gz release/osx/
cd release/osx
<change MPLVERSION=0.98.5.3 to MPLVERSION=0.98.6svn in the Makefile>
make installers
and it fails. Here are the last couple of lines:

Hello
I have a little problem.
On figure I have 2 Axes created by
 fig = plt.figure(figsize = (16, 10), facecolor='w')
 ax1 = fig.add_axes([0, 0, 1, 0.1])
 ax2 = fig.add_axes([0.1, 0.19, 0.8, 0.72], autoscale_on=True)
There are some text and images on it:
 ...
 drawing on ax1 and ax2
 ...
 ax1.imshow(arr, extent=[0.01, 0.29, 0.1, 0.95])
 ax1.imshow(arr, extent=[0.75, 0.96, 0.5, 0.8])
 ...
My problem - when I plot the figure - ax1 changes it's geometry.
Code:
 print 'ax1:', ax1
 print 'ax2:', ax2
 plt.show()
 print 'ax1:', ax1
 print 'ax2:', ax2
 print 'ax1 position changed during plt.show(). Why???'
Output:
 ax1: Axes(0,0;1x0.1)
 ax2: Axes(0.1,0.19;0.8x0.72)
 ax1: Axes(0.470649,0;0.0587025x0.1)
 ax2: Axes(0.1,0.19;0.8x0.72)
 ax1 position changed during plt.show(). Why???
On resulting plot ax1 has position (0.470649,0;0.0587025x0.1), but 
desired are (0,0;1x0.1).
Could anyone help me, or give an idea, why axes is moved, or give an 
advice, how to resolve this situation.
Thank you

hi there, I stumbled into yet another problem, see script attached. Now 
there are 10 pixels and 10 label values on each axis, but I get only 
half the ticks, and as a result half the labels get discarded... How can 
I specify the number of ticks it uses?
Note that I could use plt.pcolor(np.array(EMINS),np.array(ROIS),d) and 
at least the labelling would be correct, but the pixels are now more or 
less wide depending on the interval between values, which was not 
intended....
thanks a lot in advance for your help,
Johann

Hi all,
I've installed environment following this installation instructions:
http://matplotlib.sourceforge.net/users/installing.html
I had already installed GTK 2 and PyGTK the day before (the most recent
versions) and then installed last version of numpy, matplotlib and ipython.
Everything was ok but when I tried a sample script I've found out that the
module _backend_gdk was missing.
The script failed on this import:
from matplotlib.backends.backend_gtk import FigureCanvasGTK as FigureCanvas
due a missing module that backend_gdk (imported by backend_gtk) tries to
import.
The missing module is _backend_gdk.
I commented that import statement (used to import pixbuf_get_pixels_array)
and the sample script run without any problems.
However, I guess that I need _backend_gdk module and something went wrong
during installation.
Can you help me in solving this issue? I did a googling but it seems that
few others have this problem (since most of users use linux, perhaps) and no
solution was reported.
Thanks in advance!
PS: python version is 2.5 so I installed all py2.5 of libs above.

Thanks JJ, I'll give that a shot. The problem with making them invisible is
they take up a lot of unnecessary overhead in my vector graphics program
that already runs ridicuslow :)

Experimenting in ipython (run ipython --pylab) is excellent for this; 
not only do you see results promptly, but
help(pylab)
lists, for instance, the functions xlim and ylim, with which you can 
get and set any of the four axis limits.

Please check set_xlim and set_ylim.

One can set axis limits via a command like the following:
pyplot.axis([0 10 0 1])
But, there are situations where I'd like to set limits only for the y-axis,
leaving the x-axis alone, or vice versa, or set a lower limit for the y-axis
but leave the upper limit alone. Is there a clean way of doing this? (I
have not been able to find anything relevant in the Matplotlib Users Guide).

Hi Phillip,
Don't you need to call
pyplot.show()
at the end of the script?

Hmm, I don't think you copied that quite right.
Anyway::
 import numpy as np
 from matplotlib import pyplot as plt
 x= np.arange(0,10.,0.1)
 y= x**1.5 - 0.25*x**2
 fig = plt.figure(figsize=(9, 6), dpi=120)
 myplot = plt.plot(x, y)
 plt.show()

Or run inside "ipython -pylab".

Add this to the end of the script (after all the plotting):
 pyplot.show()
