matplotlib-users Mailing List for matplotlib (Page 10)

Iv got an error , when all the value in the list is the same,
" b=points[a+1]-points[a]"=0
then "list_progre"=[0,0,0,0,0,0,0]
and then : "progres=plot(dt_date, list_progre, '')" made me an error : 
"var = dv/max(abs(vmin), abs(vmax)) ZeroDivisionError: float division"

what can i do to stop this error

thx

The program test:

from pylab import *

list_progre=[]
dt_date=[12,13,14,15,16,17,18,19]
points=[25,25,25,25,25,25,25,25]
num_fig=1
nom='test'
chemin_fichier='C:\Python24\uni_33\\'

long_list=len(points)-1
a=0
while a<long_list :
    b=points[a+1]-points[a]
    list_progre.append(b)
    a=a+1

f=figure(num_fig,figsize=(8,6), dpi=72)
subplot(211)
classt=plot(dt_date, points, '')
setp(classt, color='r', linewidth=2.0)
title('Nombre de point au classement general')
xlabel('time')
ylabel('points')
del(dt_date[0])
subplot(212)
progres=plot(dt_date, list_progre, '')
setp(progres, color='g', linewidth=1.0)
title('Progression')
nom_fichier=string.replace(nom,' ','_')
rep_fichier=chemin_fichier+'stat_img\\'
savefig(rep_fichier+nom_fichier, dpi=50)
show()
#f.clf()

Is there a way to programmatically write line labels, as in the
attached image?  If it doesn't go through the list, basically I want a
label at the end of each of 10 or so lines in a plot.

Tx

New compile to match numpy-0.9.8.
win32-py2.4 coming tomorrow morning...

2006-04-05 Use python's subprocess module for usetex calls to
           external programs. subprocess catches when they exit
           abnormally so an error can be raised. - DSD

2006-04-03 Fixed the bug in which widgets would not respond to
           events.  This regressed the twinx functionality, so I
           also updated subplots_adjust to update axes that share

2006-03-28 More changes to aspect ratio handling; new PBox class
           in new file pbox.py to facilitate resizing and repositioning
           axes; made PolarAxes maintain unit aspect ratio. - EF

2006-03-23 Refactored TextWithDash class to inherit from, rather than
           delegate to, the Text class. Improves object inspection
           and closes bug # 1357969 - DSD

2006-03-22 Improved aspect ratio handling, including pylab interface.
           Interactive resizing, pan, zoom of images and plots

And just to prove that ipython is wedded to mpl til death do us part:

http://scipy.net/pipermail/ipython-user/2006-June/001750.html

We put 0.7.2 of ipython out also yesterday, and it does include a
number of fixes to the threading support that pylab requires with the
WX, GTK or Qt backends.

Cheers,

ps - it seems the matplotlibrc file at:

http://matplotlib.sf.net/matplotlibrc

is a bit outdated:

In [1]: import matplotlib
/home/fperez/tmp/local/lib/python2.3/site-packages/matplotlib/__init__.py:947:
UserWarning: Bad val "free" on line #204
        "image.aspect : free              # free | preserve"
        in file "/home/fperez/.matplotlib/matplotlibrc"
        not a valid aspect specification

The one in the source distro is fine (I'm in the middle of updating,
so I noticed).

mathtext doesn't currently support frac (but hopefully it will by the
end of the summer as we have a google summer-of-code student working
on mathtext).  As Ryan noted, if you have access to TeX/LaTeX on your
system, you can use that to render your equations

Requirements:

  tex

  *Agg backends: dvipng

  PS backend: latex w/ psfrag, dvips, and Ghostscript 8.51
  (older versions do not work properly)

You can set matplotlib up to use LaTeX, but it can be a little bit of
work to get it going.  The results are quite beautiful though.

set usetex = 1 in yout matplotlibrc file to try it out.  It depends on
LaTeX, dvipng, and ghostscript.

Does anyone know the syntax for fraction used in mathtext?  The LaTex
version is \frac{num}{denom} but this gives an error.

The script examples/backend_driver.py does just this -- it runs a
most of the examples and generates output in a variety of formats
(PNG, PS, SVG).  I usually tun this before releases and load all the
images into a viewer to check for bugs.  We could add these generated
images to a web page...., but sourceforge is already complaining that
I am over my quota.  Apparently, I can ask for more space, though.

JDH

I have always felt that it would be useful to have available a 
collection of plots corresponding to the code in the examples file as 
part of the distribution. (for those examples that generate plots, of 
course)
The plot names would be the same as the example code that generated 
them. It could be in an economical format (png?) so as to not take up a 
lot of space.
For my own part, I tend to be lazy and would like a way to peruse the 
new capabilities  before I decide to install the new release or wait 
for the next.
This would also provide a complete gallery to help those considering 
adoption.
It would also provide a verification for persons testing a new install 
that this is what the results of running the examples should be.

just an idea.

Hi,

I am using a second y axis on the right with twinx() like the
following:

ax =3D subplot(111)
plot_date(..., label=3D'foo')
ax.xaxis.set_major_locator(month3)
ax.xaxis.set_major_formatter(DateFormatter('%Y-%m'))
ax.xaxis.set_minor_locator(month1)
ax.autoscale_view()
labels =3D ax.get_xticklabels()
setp(labels, rotation=3D60)
ax2 =3D twinx()
plot_date(..., label=3D'bar')
[...]

I am then repeating the xaxis.set_* functions for ax2 so that they
overprint the ax ones, otherwise I get two differently formatted x
axes. I would however just like to use the first xaxis setting and
not print it for ax2 at all - how could I do that?

Also, I can't find how to merge the two labels 'foo' and 'bar' into
a single legend, is there way to do that?

TIA,
  Colin

+1 for removing pcolor_classic.

This is a previously reported problem, related to:

a) closing figures (garbage collection)
b) memory usage issues (and memory leaks, which depend on the selected 
backend)

I adapted the script just provided by John Hunter to show memory usage 
at each new figure:

import sys
import pylab
import os
import time

report_filename = 'memory_report_in_%s.txt' % pylab.matplotlib.get_backend()
fid = file(report_filename,'wt')
fid.write('Date/time of test   = %s\n' % time.asctime())
fid.write('OS version          = %s\n' % os.sys.version)
fid.write('OS platform         = %s\n' % os.sys.platform)
fid.write('Matplotlib version  = %s\n' % pylab.matplotlib.__version__)
fid.write('Matplotlib revision = %s\n' % pylab.matplotlib.__revision__)
fid.write('Matplotlib backend  = %s\n' % pylab.matplotlib.get_backend())
      
pylab.ion()
a=pylab.arange(0,10)

def report_memory():
    ### Attention: the path to the pslist utility should be adjusted 
according to installation!
    if os.sys.platform == 'win32':
        ps_exe_filename = os.path.join(os.getcwd(),'pslist.exe')    
#Build ps filename
        a = os.popen('%s -m python' % ps_exe_filename).readlines()  
#Build and execute command
        b = a[8]
        c = b.split()
        return int(c[3])
    else:
        print 'Sorry, you have to adapt the command for your OS!'
        return 0

while 1:
    fig = pylab.figure()
    ax = fig.add_subplot(111)
    x, y = pylab.nx.mlab.rand(2,30)
    ax.plot(x,y,'o')
    fig.canvas.draw()
    memory_usage=report_memory()
    k = raw_input("Current memory usage %d [kBytes]. Press any key to 
continue, q to quit: " % memory_usage)
    fid.write('%8d [kBytes]\n' % memory_usage)
    if k.lower().startswith('q'):
        fid.close()
        sys.exit()
    pylab.close()
show()

Results using TKAgg are given below:

Date/time of test   = Tue Jun 06 16:32:02 2006
OS version          = 2.4.3 (#69, Apr 11 2006, 15:32:42) [MSC v.1310 32 
bit (Intel)]
OS platform         = win32

   32300 [kBytes]
   34436 [kBytes]
   36660 [kBytes]
   38780 [kBytes] ....

Results using GTKAgg are much better (given below):

OS version          = 2.4.3 (#69, Apr 11 2006, 15:32:42) [MSC v.1310 32

   35244 [kBytes]
   35336 [kBytes]
   35392 [kBytes]
   34364 [kBytes]...

As suggested by Hunter some time ago, TkAgg is leaking (under Win32). If 
TkAgg is placed as the "default" backend for
Win32 users, maybe this problem should deserve some attention.
With GTKAgg (and also some other backends tested) everything seems to be 
fine!

In the spirit of cleaning up and simplifying mpl, I would like to know 
whether anyone is still using pcolor_classic, and if so, why?  Does it 
have any advantages over pcolor or pcolormesh?

Thanks.

Hi,

I'm trying to do a simple linear least squares fit of some data in an 
application.

The relevant code runs about as follows, following closely the example 
found on http://mail.python.org/pipermail/python-list/2006-March/331693.html

---------
import matplotlib.numerix as nx

contact_x_points=nx.array(x_points[left_bound:right_bound])
contact_y_points=nx.array(y_points[left_bound:right_bound])

A=nx.ones((len(contact_x_points),2))
A[:,0]=contact_x_points 
result=nx.linear_algebra.linear_least_squares(A,contact_y_points)
---------

...but when I run, it crashes with:

File "hooke.py", line 202, in find_contact_point
     result=nx.linear_algebra.linear_least_squares(A,contact_y_points)
   File "/usr/lib/python2.3/site-packages/Numeric/LinearAlgebra.py", 
line 416, in linear_least_squares
     nlvl = max( 0, int( math.log( float(min( m,n ))/2. ) ) + 1 )
OverflowError: math range error


I also tried using scipy:
-----------
import scipy as sp

contact_x_points=sp.array(x_points[left_bound:right_bound])
contact_y_points=sp.array(y_points[left_bound:right_bound])

A=sp.ones((len(contact_x_points),2))
A[:,0]=contact_x_points           result=sp.linalg.lstsq(A,contact_y_points)
-------------

... with another error:

array_from_pyobj:intent(hide) must have defined dimensions.
rank=1 dimensions=[ 0 ]
Traceback:
[...]
File "hooke.py", line 202, in find_contact_point
     result=sp.linalg.lstsq(A, contact_y_points)
   File "/usr/lib/python2.3/site-packages/scipy/linalg/basic.py", line 
344, in lstsq
     overwrite_b = overwrite_b)
flapack.error: failed in converting hidden `s' of flapack.dgelss to 
C/Fortran array

In my .matplotlibrc the numerix backend is Numeric.
I'm on Debian Sarge; MPL version is 0.82 ; Scipy is 0.3.2


It must be noticed that I fail to declare

A=nx.ones((len.contact_x_points),2),dtype=float)
as the example should seem to require, because it gives me another error:

TypeError: ones() got an unexpected keyword argument 'dtype'

...so if this is the problem, please tell me how to correctly pass the 
dtype argument.

Since I'm quite a scipy/numeric newbie I guess there could be some 
obvious blunder and/or more correct way of obtaining my fit, and I'd be 
thankful to anyone pointing me at the solution...

Thanks,
Massimo

Hi you all

I am coding a GUI application python/matplotlib/basemap based on. I have 
imported NavigationToolbar as follows:

from matplotlib.backends.backend_gtk import NavigationToolbar2GTK as 
NavigationToolbar

This shows the following five buttons:

1.- Reset Original View
2.- Back to Previous View
3.- Forward to Next View
4.- Pan Axes
5.- Zoom to Rectangle
6.- Save the Figure

I am really interested on buttons number 1, 4, 5 and 6 only. Is it possible 
to suppress the other buttons from tha toolbar??? how??. The second issue is 
i would like to change toolbar tooltips from english to spanish which is my 
mother tonge...

I would like to know wether this customizing options are possible...
Thanks for your answers in advance....

Regards.-

Often times what people are looking for is they want to the figure to
pop up on the screen, look at it, have it close, and move on.  One way
to achieve this is to run mpl in interactive mode

  http://matplotlib.sf.net/interactive.html

and then insert a time.sleep or call 

  input("Press any key for next figure: ")

If this is what you are doing, threading becomes important.  This is
discussed on the web page linked above, and your best bet is to either
use the tkagg backend or better yet, use ipython in -pylab mode.

Something like

import sys
from pylab import figure, close, show, nx, ion

ion()

while 1:
    fig = figure()
    ax = fig.add_subplot(111)
    x, y = nx.mlab.rand(2,30)
    ax.plot(x,y,'o')
    fig.canvas.draw()
    k = raw_input("press any key to continue, q to quit: ")
    if k.lower().startswith('q'): 
        sys.exit()
    close()
show()

Are you using TkAgg?
Then it should have a close button.
Use it.

By using show() you entered the Tkinter mainloop,
so you cannot close it from the console.
(Or so I believe.)

Not absolutely sure what you mean, but to produce some plots and save
them in a loop I do

f = figure()
for i in range(..):
	plot(...)
	savefig(...)
	f.clf() # clear figure for re-use
close(f)


cheers,

Eek! Local changes in my repository.  Please disregard the previous

Hi,

In current SVN, line 1164 of text.py (__init__ of TextWithDash) refers
to "renderer" which is not defined.  This breaks almost any operation.

I made some figure in a loop and i want to close after the figure show.

thx

OK, thanks. I had not realized that so few dirs were searched on Windows 
as compared to unix/MacOS X, but you're right. So although the test for 
frozen windows versions comes last, there's not much to collide with 
before that.

I guess it's a bit old. 0.82. I need something built for MacOS X 10.3.9 
so my bundled app runs on that.

Thanks for the heads up on the changed path. Maybe I'll remember to fix 
my bundling code when I upgrade matplotlib.

Great idea. I'll do that. Thanks!

Thanks for the tip. I knew about the first one, but not the second!

Hi you all,

I am using matplotlib toolkits to draw maps of my country, cities and 
specific locations. I would like to draw markers on the maps too....

I have been looking for a sample code that indicates how to asign a text 
label to the markers in orther to add to each marker the location´s name....

Any suggestion???

thanks for your help in advance
Juan

I also had problems installing matplotlib with numpy on windows.
Basicaly, I installed matplotlib, didn't create the matplotlib rc file
(it isn't created by the installer), and it turned out, that by
default, pylab needed  numeric, not numpy.

Now back to inspecting the internals of matplotlib :)
