matplotlib-users Mailing List for matplotlib (Page 5)

I am making a polar plot, and the ticklabels are overlapping the plot a little 
bit. I tried to compensate by increase the tick.major.pad rc setting, but it 
does not seem to be respected.
Any suggestions on where to look for this?
from matplotlib import rcParams
rcParams['tick.major.pad']=10
rcParams['tick.labelsize']=16
from pylab import cos, figure, frange, pi, polar, sin, show
figure(figsize=(4,4))
ang = frange(0,10,.01)*2*pi
polar(ang, sin(ang)*cos(ang))
show()

The basemap add-on toolkit for matplotlib allows you to plot your data 
on a wide variety of map projections, with coastlines and political 
boundaries.
For an example of what it can do, see See 
http://www.scipy.org/wikis/topical_software/Maps.
This is mainly a bugfix release, with one significant new feature - the 
ability to plot data in ESRI shapefiles (thanks to pyshapelib by 
Bernhard Herzog).
Download it at http://sourceforge.net/projects/matplotlib/

Sorry to have bothered you with this!
There was no problem at all with the string passing; my problem was 
somehow different, and now mathtext works just fine. Great!
So just forget about my question ;-)

Hi all,
The title is not illustrated but for what reason ?

Should be pretty easy. Take a look at

Hello everyone,
I intended to use the capabilities of mathtext as presented on the 
matplotlib example page and the tutorial page. The examples given are 
quite clear; yet they always assume that you pass the string that should 
be interpreted as raw string, e.g.
r'$\sum_{i=0}^\infty x_i$'
However, in my application the user types the labels/title/whatever text 
in a gtk entry field and this string, which is a unicode string, is then 
passed on to the matplotlib OO interface. And as it is right now, I 
just get the text as it is, so no fancy sum or infinity sign.
I'd appreciate your help,
Niklas.

As you've discovered, tex support has not been implemented yet for the
svg backend. Feel free to submit a support request on the sf site.
Perhaps the path of least resistance would be to embed the tex
graphics as images, just as we do for agg, since SVG already has image
support.

No problem. As penance, you can write the patch to texmanager.py or
__init__,py (on the usetex rc param check) that issues a proper
warning if dvipng is not installed. I personally think it should be
made in matplotlib.texmanager.TexManager.get_dvipng_version. Frankly,
I don't understand why the current implementation failed 
 def get_dvipng_version(self):
 if self.dvipngVersion is not None: return self.dvipngVersion
 sin, sout = os.popen2('dvipng --version')
 for line in sout.readlines():
 if line.startswith('dvipng '):
 self.dvipngVersion = line.split()[-1]
 return self.dvipngVersion
 raise RuntimeError('Could not obtain dvipng version')
OK, on a second read of the texmanager code, I do understand.
Apparently the error is that this function is not called by make_png.
I think all that is needed is to add a version check to make_png
which calls get_dvipng_version which will raise if dvipng is not
defined. Send patches to me, to this thread, to the devel list, or to
the sourceforge site.
Thanks!

John,
It appears that the conflict , configuration problem is in my Eclipse
IDE or it's pydev plugin I use for development. I have now been able
to run the code from a DOS prompt, and after installing the newest
Eclipse3.1 version and pydev plugin the Agg backends now function
normally for savefig() .
Thanks again!

John,
As you said I also believe it is likley to be a configuration/conflict
error. I recieve the same error below any time I attempt to use
savefig() with an Agg backend. The script below is an example file to
show it happens on even the most simple code. I was wondering if any
one had seen this , or could give me an idea of where to look for
removing the conflict. Are there file dependencies I should be looking
at , outside of Matplotlib?
Thanks again!

I tried to replicate this problem and could not. I did a clean
install of 0.83.2 on windows XP for python23 and Numeric 23.7 and your
test script ran fine for me. That makes it harder to fix.
I reread your original post and you are getting the error
 File "C:\Python23\Lib\site-packages\matplotlib\agg.py", line 809,
 in move_to
 def move_to(*args): return _agg.path_storage_move_to(*args)
 TypeError: argument number 1: a 'path_t *' is expected,
 'path_storagePtr(<agg.path_storagePtr; proxy of C++
 agg::path_storage instance at _208aa401_p_agg__path_storage>)' is
 received
Is this the one you are still getting? For some reason it appears
that the SWIG typedef 'path_t' for 'agg::path_storage' is not being
properly handled on your system.
Can you provide any more information (exact operating system, other
things you've installed, any nonstandard path settings, etc). I
assume the script you posted is the one you are working with, and you
are not importing anything except pylab.
Here is what I am testing with
from pylab import *
plot(arange(10), color='#006400')
xlabel('this is a xlabel\n(with newlines!)')
ylabel('this is vertical\ntest', multialignment='center')
#ylabel('this is another!')
text(2, 7,'this is\nyet another test',
 rotation=45,
 horizontalalignment = 'center',
 verticalalignment = 'top',
 multialignment = 'center')
savefig('multiline')
which I run with
 C:> c:\Python23\python myscript.py -dAgg --verbose-helpful

Neat example. I cleaned it up to make more efficient and to solve
the flicker problems. In this version, all of the artists are created
once in the init function and then their data is updated on move.
This is much more efficient.
I also refactored the code to be independent of pylab and to make
Scatter3D inherit from matplotlib Axes, since since you do your own
tick lines etc. With a little work, this approach has potential for
simple 3D plots.
Thanks! I'll look over this more later.

That did it.
That's a nice first stab at 3D scatter plots, Eric.

I'll let the guru's speak to efficiency, but I have a suggestion for aesthetic 
and functionality.
I have done quite a lot of 3D design in AutoCAD, and they have a very nice 
"orbit" tool. They superimposed this compass thing over the drawing:
 ---O---
 / \
 / \
 | |
 O O
 | |
 \ /
 \ /
 ---O---
When you press the mouse button down in the N or S pole and then drag it, it 
rotates around the E-W axis. If you press the mouse button down outside of 
the compass, it rotates around the axis pointing out of the screen. I forget 
what it does when you press the button down inside the compass but not on a 
pole.
I guess this is way out of scope at this point, but I thought I'd mention it.
Darren

just for testing, note that there is a syntax problem in the line I sent 
(in laby=... one " is missing) .
So you should use:
x = array([0.,1.,2.,3.])
y = array([1.,0.,3.,2.])
z = array([4.,3.,0.,1.])
tmp = pxyz(x, y, z, labx="x", laby="y", labz="z")
sorry for this.
Eric

Hi,
I needed to see visualize a set of points in 3D (scatter plot) and to be 
able to rotate the axes easily in a way similar to gnuplot.
I have thus written a short python routine using matplotlib for the visu 
part (attached below).
It works simply by doing something like:
###########################################
x = array([0.,1.,2.,3.])
y = array([1.,0.,3.,2.])
z = array([4.,3.,0.,1.])
try = pxyz(x, y, z, labx="x", laby=y", labz="z")
###########################################
It does show the 4 points in projection, including the projection of the 
x,y,z axis. And each time you move the mouse within the figure, it will 
move the projection accordingly, showing the 3D scatter plots and the 3 
unit axes again.
(the projection is defined via 2 rotation angles, theta - around x - and 
phi - around z).
Now I realize this is really a naive way of doing such an exercise. The 
updating (projecting, refreshing, and reploting all points everytime, 
positions of the axis labels, etc) is very far from optimal (slow and 
somewhat ugly) mostly because I am a beginner here. So I was wondering 
if anyone on-line had produced a similar but somewhat refined version of 
this, or if you had any suggestion of how to improve the 
speed/efficiency, esthetic and functionality of such a routine? At the 
moment I am plotting 48 points... But I can imagine such a routine could 
just be unusable with 1000 points...
Any input is welcome!!!
Thanks,
Eric

I tried to replicate this problem and could not. I did a clean
install of 0.83.2 on windows XP for python23 and Numeric 23.7 and your
test script ran fine for me. That makes it harder to fix.
I reread your original post and you are getting the error
 File "C:\Python23\Lib\site-packages\matplotlib\agg.py", line 809, 
 in move_to 
 def move_to(*args): return _agg.path_storage_move_to(*args) 
 TypeError: argument number 1: a 'path_t *' is expected, 
 'path_storagePtr(<agg.path_storagePtr; proxy of C++ 
 agg::path_storage instance at _208aa401_p_agg__path_storage>)' is 
 received 
Is this the one you are still getting? For some reason it appears
that the SWIG typedef 'path_t' for 'agg::path_storage' is not being
properly handled on your system.
Can you provide any more information (exact operating system, other
things you've installed, any nonstandard path settings, etc). I
assume the script you posted is the one you are working with, and you
are not importing anything except pylab.
Here is what I am testing with
from pylab import * 
plot(arange(10), color='#006400') 
xlabel('this is a xlabel\n(with newlines!)') 
ylabel('this is vertical\ntest', multialignment='center') 
#ylabel('this is another!') 
text(2, 7,'this is\nyet another test', 
 rotation=45, 
 horizontalalignment = 'center', 
 verticalalignment = 'top', 
 multialignment = 'center') 
savefig('multiline') 
which I run with 
 C:> c:\Python23\python myscript.py -dAgg --verbose-helpful

John,
Thank you for the reply!
It does not seem to matter if I use .png or leave off the extension (as
I really should have). I have uninstalled , and reinstalled Matplotlib,
and Numeric. And in a final check even reinstalled Python. Same
errors. I can see the agg backends are in the default directories , and
the paths seem to allow access to them, the errors seem to happen during
rendering or saving.

Call subplots_adjust(hspace=0.1), etc.
This is a pylab method that applies to the current figure
 fig = figure()
 subplots_adjust(hspace=0.1)
or if you prefer a Figure method
 fig.subplots_adjust(hspace=0.1)
The default values are set in your matplotlibrc file
http://matplotlib.sf.net/matplotlibrc
 # The figure subplot parameters. All dimensions are fraction of the
 # figure width or height
 figure.subplot.left : 0.125 # the left side of the subplots of the figure
