matplotlib-users Mailing List for matplotlib (Page 5)

Hello,

I would like to resize a matplotlib window from a command in ipython. I 
don't want to use the mouse to do this (for different reasons). Do you 
know if it's possible to do this?

Thanks

N.

Fixed in CVS.  There was a clipping bug in the draw_image function
that underlies the tex drawing to *Agg.

Sorry, I guess I missed your last email.  I'll look into it.  If the 
script is more complicated than "plot_something(); show()", could you 
please send a copy of it?  Thanks.

Apparently, whatever this problem is, it is caused by calling pylab.figure(=
#)

In [1]: pylab.figure(1)

** (python:8692): WARNING **: IPP request failed with status 1030
Out[1]: <matplotlib.figure.Figure instance at 0xb517f02c>

I can recreate this without any script with just that one command.  I
am running matplotlib 0.84, IPython 0.6.16_cvs, and scipy
0.3.3_309.4626 on ubunut Breezy 5.10.

Any thoughts?

Ryan

Robert:  But this refers to modifications made to it "in the same 
file".    The way I read this, if we don't change his source files we 
can redistribute them any way we want, as long as we leave the CSIRO 
copyright notices alone.

Hi,

I am trying to use matplotlib 0.84 with Python 2.4.2 on Wondows XP with
idle -n. I did this in the past with the 2.3.5 and some older version of
matplotlib without any problems.

Now I have some problems. I started with a really fresh installation of
Python and added first the Numeric 23.8 module. After that I installed
matplotlib 0.84 and changed the matplotlibrc (tk.pythoninspect  : True).

Within Idle I get the following printout:
>>> from pylab import *

Hi John and list,

Sorry to take your time.

from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg as 
FigureCanvas
from matplotlib.backends.backend_gtkagg import NavigationToolbar2GTKAgg 
as NavigationToolbar

when i do:

    |fig = Figure(figsize=(5,4), dpi=100)|||
    |ax = fig.add_subplot(111)             # 1|
    |t = arange(0.0,3.0,0.01)|
    |s = sin(2*pi*t)|
    |ax.plot(t,s)|||||
    |canvas = FigureCanvas(fig)|
    |vbox.pack_start(canvas)|
    |toolbar = NavigationToolbar(canvas, win)|
    |vbox.pack_start(toolbar, False, False)
    |

|I can zoom on the figure and it is redrawn.

    |fig = Figure(figsize=(5,4), dpi=100)
    ax = Subplot(fig,111)         ||        # 1||
    t = arange(0.0,3.0,0.01)

    |canvas = FigureCanvas(fig)
    vbox.pack_start(canvas)
    toolbar = NavigationToolbar(canvas, win)
    vbox.pack_start(toolbar, False, False)|

The application is crashing. GTK seems to fail displaying the canvas.

Is it a bug or am i doing something wrong?

Thanks a lot for the answer,

Hi John,

I have submitted a bug report a few weeks ago.

http://sourceforge.net/tracker/index.php?func=detail&aid=1296124&group_id=80706&atid=560720

How about that ?

Tim,

Sorry I can't help much, but:

> I have attempted to use numarray from cvs but I can't build it - no VC7

You can build Python extensions with MinGW. You have to do a little 
patching to Python, but it's not too hard, and it does work.

Here's one link. Googling will get you others:

Hi all,

First thanks to all those who have been helping out - it is really 
appreciated.

I have cross posted to the numarray, py2exe and matplotlib lists

I have attempted to use numarray from cvs but I can't build it - no VC7

clang - did a penny drop anywhere?

I am working with python 2.4.1 and numarray 1.3.3 for 2.4 (obviously)

Since I couldnt build numarray - I looked at the new import code in the 
cvs init module and ripped it off and stuffed it into my numarray 
installation and then when that didnt work  - I jammed it right up front 
of my application.

It looks like this

def main():
     import numarray.numarrayall
     from numarray.numinclude import version as __version__

     # stolen from next numarray version in cvs TjB

     import numarray._conv
     import numarray._sort
     import numarray._bytes
     import numarray._ufunc
     import numarray._ufuncBool
     import numarray._ufuncInt8
     import numarray._ufuncUInt8
     import numarray._ufuncInt16
     import numarray._ufuncUInt16
     import numarray._ufuncInt32
     import numarray._ufuncUInt32
     import numarray._ufuncFloat32
     import numarray._ufuncFloat64
     import numarray._ufuncComplex32
     import numarray._ufuncComplex64
     import numarray._ndarray
     import numarray._numarray
     import numarray._chararray
     import numarray._objectarray
     import numarray.memory
     import numarray._converter
     import numarray._operator
     import numarray._numerictype
     import numarray.libnumarray
     import numarray.libnumeric
     import numarray._ufuncInt64
     import numarray._ufuncUInt64

     print numarray.__version__

     application = BoaApp(0)

Still no go - but a changed error message.... grrr

I get

Traceback (most recent call last):
   File "AEMdaApp.py", line 81, in ?
   File "AEMdaApp.py", line 41, in main

ok I confess my bottom lip trembled....

then - probably because I was reading the numarray manual this morning - 
I went to my numarray install and decided to run testall.py

I got

and so on for quite some time.

Hmm the message about
	memory.memory_from_string
and my applications
	ImportError: init_ndarray: can't find memory.new_memory

are these a little related? Am I clutching at straws?

Yet my app runs fine under any ide I wish to use.

WAIT!  - my install of numarray is broken....
I deleted it and reinstalled - still broken
I installed on my laptop and tested - broken there too

My legacy python 2.3 and numarray 1.3.3 installation passes all the 
tests just fine.

Is there a problem with python2.4.1 and numarray 1.3.3?

Could some kind soul build me a numarray windows installer for python 
2.4 from cvs - please - so that I can see if that works better with py2exe.

I need a stiff drink

Charlies, Chris, and Arnd: thanks for your prompt responses to Ryan's 
question!  I'll write up a cookbook entry on the topic tomorrow.

I've known about the missing wxPython headers for some time and have 
been corresponding with the Debian package maintainer about it.  
Apparently the headers weren't getting installed in 2.6 due to some 
Extreme Cleverness on the part of wxPython's "setup.py" and in 2.4 
there wasn't even an attempt to install them.  Last Thursday I filed 
patches on sourceforge, so hopefully this'll get fixed sometime soon.

While writing this email, I noticed that the 0.83.2 package has been 
pulled from the repository on anakonda.  Samuel, try uninstalling and 
then re-installing python2.3-matplotlib.  That will hopefull end up 
downgrading you to version 0.82, which I believe works fine under GTK.

I believe that there is a problem with the Debian package itself, 
rather than with Samuel's installation of Debian.  I have been able to 
reproduce this problem on a machine running Debian sarge.  I hadn't 
noticed it until now because I don't use the GTK backends:

kmcivor@ivory:~$ dpkg-query -l | fgrep python-matpl
ii  python-matplot 0.83.2-2       python based plotting system in a

The problem Samuel is having appeared on the debian-science mailing 
list about a week ago.  At the time I couldn't figure out where the 
dependency on libpangocairo was coming from, but your comment about gtk 
made the light bulb go on.

According to the "search the contents of packages" function on Debian's 
packages page, there are no files containing the phrase "pangocairo" in 
any package in Debian sarge, testing, or sid.  However, libpango-1.0 in 
Ubuntu Breezy Badger (their current testing distribution?) does contain 
libpangocairo and friends.  My guess is that the package was built on a 
machine running Ubuntu testing/unstable.

My view is that it is always worth asking for a different
license before giving up.  Many people choose 
licenses thoughtlessly.  Some not, of course.

No, the CAPITALIZED part is very much not okay. It means we'd have to
sign over the copyright to our modifications to CSIRO, and that the code
can't be embedded in a commercial or proprietary project.

I don't think so.   For matplotlib we use import_array() because that's 
the init call for numarray's Numeric compatible interface.   I think 
Tim's import_libnumarray() message is originating from numarray as it 
tries to call it's own API,   most likely because the numarray 
installation is broken so the import failed.  

Here's a couple other facts:

1.  The import_libnumarray() message is confusing because I didn't think 
numarray import failures would occur in a sane world... so import 
failures in numarray-1.3.3 look the same as uninitialized extensions. 

2.  numarray uses it's own API to share code internally,  so when 
numarray's rather complex import fails,  the first internal call to it's 
own API generates the cryptic fatal error.

numarray CVS does two new things that are about a week old:

1. It correctly reports numarray's own import failure with a fatal 
error.  This should clarify future problems if there are any.

2. Explicit imports of core extensions were added to numarray.__init__ 
so that py2exe can figure out what extensions must be included in an 
installer.   This should actually solve the problem.

Those fixes address "exactly the same symptoms" (py2exe + cryptic fatal 
unitialized API error message) seen by another user who tested the fix 
on two different installer tools.

Nope,  don't think so.

Could that someone be us?

I tried

in my src tree and got zippo.

We call 

  import_array();  

....

Is this a matplotlib bug.  If so, I'll be happy to patch it and roll
out a bug-fix release.

John:  I will do this and let you know.  I agree with Robert on qhull - 
it's not the way to go.  I did find this however:

http://www.marine.csiro.au/~sakov/

Bivariate spline-based techniques offer robust and efficient 
approximation solutions. Here `csa' (standing for "cubic spline 
approximation") is a small library for approximating 2D irregular 
(scattered) data with bivariate C1-continuous cubic splines 
<http://www.math.uni-mannheim.de/%7Elsmath4/paper/VIS2001.pdf.gz>. For 
uniformly distributed data this algorithm is clearly superior than 
Natural Neighbours interpolation: it is faster (O(n)!), more robust 
(approximation, not interpolation) and better performing (C1!). (But 
take care when dealing with clustered data.) From version 1.09, `csa' 
can take advantage of the known variance of the data.

Either an extension in your application forgot to call 
import_libnumarray() or the numarray distributed as part of your 
application is incomplete or broken and the import failed.  numarray CVS 
now makes a better report of which is true.

My guess is that in the development environments numarray is already 
correctly installed.

I may not understand you,  but when numarray is all there,  "import 
numarray" should work just like for any other Python package.   I think 
your problem is that numarray is not being included correctly in your 
installer because it's  extension  dependencies are hard for py2exe to 
detect correctly.   I believe this is fixed now in numarray CVS.

> Or how do you get import_libnumarray to run?

import_libnumarray() is something an extension writer must explicitly 
call in their extension init() if they want to use the numarray API.

Try using numarray CVS to generate your installer.  Last week someone 
had a similar issue with this and I added code to numarray.__init__ to 
explicitly import all numarray's core extensions.   That user reported 
that the extra "hints" in numarray.__init__ helped py2exe detect the 
necessary numarray extension set correctly,  numarray was thus installed 
correctly,  and the installer worked.

So, if I got it right, I compile and install libpng in a local directory,
point an environment variable MPLIB_BASE
to the /usr/local equivalent (not to the actual directory containing
libpng.so, usually /usr/local/lib) and then run

python setup.py build
python setup.py install --prefix $HOME/local

This is getting really frustrating, did it, same error:

ImportError:
/homes/morlet/aborghgr/local/lib/python2.3/site-packages/matplotlib/_nc_ima=
ge.so:
undefined symbol: png_set_sBIT

And png_set_sBIT is present in the local install of libpng, that one isn't
stripped of symbols.

This is what you need to do. It should be possible to factor out (or
not explicitly list) numarray's Packages, but core numarray is not
meant to be distributed in pieces. The many type-specific extensions
were only added to work around a compiler problem, not to lighten
binary distributions.

Dear Kristen,

Make sure that in Gsview, EPS Clip is "ticked"

See under Options -> EPS Clip

The problem is that the EPS picture in not an A4 (or letter) canvas but
on a bigger canvas...

By editing the EPS, you'll find a line that read something like, e.g.:

...
%%BoundingBox: 162 744 1171 1753
...

The left boundingbox margin is set at 1171/72=3D16.26in (413.1mm), much
wider than an A4 (or letter) Media type


You can also set the Media size to, say, A0...

See under Media -> A0 or User Defined...

But for an EPS picture, EPS Clip would suffice...


Regards,

Peter-Jan


PS:

Because of the width of the EPS picture in LaTeX, you would need a line
like, e.g.

...
\centerline{\includegraphics[width=3D16cm]{myepsfile.eps}}
...

To scale the EPS picture for A4 paper (depending on you margins or
number of columns etc.)

Hi again

This solved the problem, however, the figure is
placed in the corner of the eps files, implying that
only the bottom left corner of the figure is actually

Hi folks

I can still not succeed saving my figures in ps or eps format with the
new ps backend file you send out. I'm using python 2.4, mpl .84. Have
tried with both Numeric and numarray.

Hi,
Still tryin' to freeze my wxmpl matplotlib application.... sigh.

This is wxpython + wxmpl + matplotlib. This has turned into one hell of 
a fight - BUT I think I am about to win. You have to keep the faith :-}

Name the py2exe issue with freezing matplotlib / wxmpl and I have been 
there fought that. I have slayed many dragons...

I now have a problem that has been asked before on this list. I have 
tried the answer that was offered- it didnt help. I think I am in a 
postion to ask a simple solid question...

When I run my application I see this....

Fatal Python error: Call to API function without first calling 
import_libnumarray() in Src\_convmodule.c

This application has requested the Runtime to terminate it in an unusual 
way.
Please contact the application's support team for more information.

I added import numarray all over the place... a previous post suggested 
that maybe Wxpython was calling numarray before I was... no I dont think 
wxpython and numarray ever need each other.

To help prove this I changed my application to this: (a boa app - so 
this code occurs early in execution but not before wxpython has been used...

    def __init__(self, parent):

        import numarray
        import numarray.numarrayall # desperate attempt to stop error 
api call without first calling import_libnumarray
   
        self._init_ctrls(parent)   # init wxpython controls
 
        print numarray.__version__

and bang my application no longer runs. If I comment out this print
