Using 2.4 does not solve it on my system.

I think I already tried that. I will try that again when I'm at my desk
tomorrow. Should it not be possible to use the windows way: write to file t=

o
communicate with gnuplot? Or does it happen like that already?

I had the same problem yesterday. I solved by using python2.4 instead of 
python2.5 which comes with Feisty as default. I couldn't find a better 
solution.

Hope that helps,

The base cause of Gnuplot.py failing is that os.popen() can't
be used if the CWD is a UNC network path.  See the link below
if you're interested in Microsoft's half-assed rationalization
of this particular bit of Windows breakage:

  http://support.microsoft.com/kb/156276/EN-US/

The answer is to change gp_win32.py so that instead of
os.popen() it uses subprocess.Popen() with shell=False.
However, there are bugs in the subprocess module that you have
to work-around:

  http://www.py2exe.org/index.cgi/Py2ExeSubprocessInteractions

Using subprocess.Popen() with the above work-arounds seems to
work.  

It also eliminates the requirement to double-quote a path that
contains a string.

After I've tested it a little more, I'll submit a patch.

I'm setting the complete path to pgnuplot.exe in GnuplotOpts.

The program works fine when started by:
  
 1) command line from any directory (local or networked).

 2) desktop shortcut icon with any 'start in' directory (local
    or networked).

 3) double-clicking an associated file in any local directory.
 
It only fails when one double-clicks an associated fine in a
network directory. I've verified that in all cases the correct
path to pgnuplot.exe is being used.  The program doesn't try to
open or access any files in the current directory.  All it does
is this:

#!/usr/bin/env python
import sys,math,tempfile,os,itertools,wx
from wx.lib.floatcanvas import NavCanvas, FloatCanvas, Resources
import wx.lib.colourdb
from sectionedFile import SectionedFile
import Gnuplot

# if we're on a Windows system and there's a pgnuplot.exe file
# in our "install" directly, tell the Gnuplot module to use
# that instead of whatever's in our PATH

sys.stderr.write("cwd: %s\n" % os.getcwd())
if sys.platform == 'win32':
    installpath = os.path.abspath(os.path.dirname(sys.argv[0]))
    gnuplotpath = os.path.join(installpath,'pgnuplot.exe')
    sys.stderr.write("installpath '%s'\n" % installpath)
    sys.stderr.write("gnuplotpath '%s'\n" % gnuplotpath)
    if os.path.isfile(gnuplotpath):
        if ' ' in gnuplotpath:
            gnuplotpath = '"' + gnuplotpath + '"'
        Gnuplot.GnuplotOpts.gnuplot_command = gnuplotpath;
        sys.stderr.write( "using pgnuplot at %s\n" % Gnuplot.GnuplotOpts.gnuplot_command)
    else:
        sys.stderr.write("didn't find pgnuplot at %s -- hope it's in your path...\n" % gnuplotpath);

import time
gp = Gnuplot.Gnuplot(debug=1)
gp('plot sin(x)')

I think that is the error that results if Gnuplot.py is not able to
start the "pgnuplot.exe" binary.  Perhaps you have a PATH problem?

[Gnuplot-py-users] Unable to get reliable operation on Win32

[Grant E. <gr...@vi...>]

I feel like I've spent the past 3 days beating my head against
a wall: no matter what I do, I can't get gnuplot-py to work
reliably on Win2K or WinXP.

It seems to work fine in the following situations:

 * Program called "normally" (e.g. python foo.py) with current
   directory containing pgnuplot.exe and wgnuplot.exe.

 * Program bundled via py2exe and called via shortcut icon
   starting in directory containing [pw]gnuplot.exe

 * Program bundled via py2exe and called via shortcut icon
   starting in different directory.

 * Program bundled via Py2exe and called via command-line from
   anywhere.

What refuses to work is when the program is started by clicking
on a file whose type has been associated with the program.  In
that case, I always get an "invalid parameter" IOError when
gp_win32.py writes to the pipe in its __call__ method.

I've switch gp_win32.py so that it uses subprocess instead of
os.popen, and that doesn't seem to help. I get either the same
error or I get an "invalid handle" when the process is being
started.

Can anybody point me towards documentation on how to get
reliable operation on Win32?

It's really not possible to describe how much I hate working
with Microsoft Windows...

I just committed a change to Gnuplot.py in r299 of trunk which allows
client code to name the option "with_" (note trailing underscore) to
avoid warnings and errors with newer versions of Python.  I also changed
the Gnuplot.py code itself so that it does not use "with" as an identifier.

However, for backwards compatibility (and through the magic of Python
varargs processing), Gnuplot.py still accepts "with" as an alternative
spelling of this option.  Thus this change should not break old clients.

Regarding your questions:

1. This change should get rid of the warnings, assuming you change your
code accordingly.

2. Rename 'with' -> 'with_'

3. Done.

[Gnuplot-py-users] "with" will be a reserved word.

[Kelvin C. <kel...@uv...>]

Hi there;

I use gnuplot-py very often because it is better suited to most of my  
tasks than other python plotting routines.  That much said, I am  
getting warnings

Warning: 'with' will become a reserved keyword in Python 2.6

I have 3 questions.

1.  Is there any way to turn off these warnings?
2.  Should I be using a different way of setting linetypes, etc. for  
plotting?

	d = Gnuplot.Data(x,y,with='lines lt 4')

3.  Is Gnuplot.py going to replace the 'with' keyword?

Thanks very much.

This usually means that pgnuplot.exe is either not installed or not in

[Gnuplot-py-users] get positions of mouse clicks?

[Grant E. <gr...@vi...>]

I've been using gnuplot-py to plot 2D and 3D wireframes for a
while.  Now I need to make my programs a little more
interactive: the user needs to be able to select lines and
points by clicking on them with a mouse.  I have found examples
of how to do this in Python:

http://www.physik.tu-dresden.de/~baecker/python/GnuplotBiDir.py

However, that Gnuplot class doesn't have many of the features
of gnuplot-py.  I'm thinking it would be easier to add
mouse-click handling to gnuplot-py than it would be to change
my programs to use the above class for the plotting.

Has anybody else worked on supporting mouse interaction using
gnuplot-py?

This is a spontaneous appreciation after an afternoon spent working with
gnuplot and gnuplot.py.

Simply a superb effort!

[Gnuplot-py-users] Installation problems from newbie

[<ma...@sc...>]

I've tried to install gnuplot-py but I've suddenly had a bad problem.
I've tried:

python setup.py install

but I've received:
Traceback (most recent call last):
  File "setup.py", line 14, in ?
    from distutils.core import setup
ImportError: No module named distutils.core

I use a SuSE SLED 10 and these are the packages I've installed:
python-2.4.2-18.2
python-numeric-24.2-14.2
python-numpy-1.0.1-0.pm.1
...

Of course I also have installed gnuplot that I can use without problem.
I've searched in the interactive interface python->help()->modules and
distutils.core doesn't appear.
Can anyone help me? Please?

Thanks a lot in advance,
Stefano C.

[Gnuplot-py-users] lack of data on graph

[Arturas <in_...@ya...>]

Hi,


After i plot graph, I get plotted just one point. It
is the first data point, but the rest vanishes from my
graph. Say it looks like:

...
g.plot([[1,2],[2,2.3],[3,5.5]])
...

So I get plotted jusr [1,2] point. Tried using
Gnuplot.Data - the same. By the way, not all demo.py
views were plotted, also !

I'm using suse 10.2, python 2.5 (intalled in user
space), gnuplot 4.0 and gnuplot-py 1.7.


Arturas
best

P.S. I've been using gnuplot.py a little time ago on
Windows XP. And it was OK'

[Gnuplot-py-users] how to suppress 'fit'-output

[Wolfgang G. <w.g...@gm...>]

I use gnuplot.py to fit data file functions via x-window. During the fit I get an output on the iteration sequences. Is there a way to suppress that annoying output?

Thank you, Wolfgang

Re: [Gnuplot-py-users] hardcopy of multiplot

Hi John,

thanks, your method is working!
One has to run all the plotting commands twice, but that's not such a big deal...

Re: [Gnuplot-py-users] hardcopy of multiplot

[John K. P. <par...@sp...>]

> s there an (easy?) way to create a eps file of a multiplot-created  
> plot?

As far as I'm aware, you need to set the terminal type and output  
before creating the plot:

g('set terminal postscript color enhanced "Helvetica" 18')
g('set output "'+filename+'"')
...
g('set multiplot')

and then make the plot as you normally would.  I close with

g("unset multiplot")
g.reset()
g('set terminal %s' % Gnuplot.GnuplotOpts.default_term)
g('set output')

though it isn't really necessary.

Gnuplot does not allow replotting (which is what hardcopy() does)  
when in multiplot mode, unfortunately (if this has changed in a very  
recent build, please let me know: I'm running 4.0).

If anyone else knows of a better method, I'd also be happy to hear of  
it.  Unfortunately, multiplot in Gnuplot can be a bit of a pain,  
particularly when trying to get several stacked plots to be the same  
size.

Good luck!
John

[Gnuplot-py-users] hardcopy of multiplot

[Marcus H. <M.H...@ls...>]

Dear all,

is there an (easy?) way to create a eps file of a multiplot-created plot?

I've created 3 three plot using the 'multiplot' option, and it looks quite nice
on the screen. But if I use the hardcopy() method on the gnuplot instance, the
resulting eps file only contains the output of the last plot() command, and all
the other plots are omitted.

I've also tried using the replot() command like

gp("set term postscript eps enhanced color")
gp("set output 'plot.eps'")
gp('replot')

, but this fails since all the temporary files that gnuplot.py creates are
already gone.

Any advice?

Cheers,
Marcus

Sorry!  Check out the latest subversion copy: I checked it in a while

Seems to be working just fine (using numpy, not numpy.oldnumeric).

Try out the latest SVN, and let me know!  I've got a few more changes
(the format for label and title fonts changed in Gnuplot at some point)
that I haven't submitted yet, but svn should be stable.

Cheers.
