Re: Re[2]: gplt and xplt

Biggles was the first Python plotting solution I tried to install but it was quite a while ago. I couldn't get
it working under Windows so it failed my cross-platform requirement. I haven't tried the more recent version.

Re: Re[2]: gplt and xplt

Alan,
just a comment on your other point -

I always assumed this was a Windows pipe-system problem. I have experienced problems in other arenas with
pipes under Win98 but not under Win2k in which the Windows pipe system changed. My experience of flakiness
with pipes driving gnuplot also followed this pattern. ie. very occasionally, I get misbehaviour
(broken plots) under Win98 but I haven't seen it under Win2k. When I experience a broken plot, I just re-run
the script and it's typically fine. I don't use it interactively from Python.

OK.
I use Windows 2000.
I installed ctypes.
I installed readline.
I installed IPython.

IPython failes with a call to readline.set_completer:
AttributeError: module has no attribute set_completer

Any ideas?

Thanks,
Alan Isaac

Which version?  There's a notice at http://ipython.scipy.org about a problem 
with 0.9 & unc-readline, which is the current one.

This is unfortunate, but beyond my control.  The unc-readline author is 
working on it, but for now the only solution is to backpedal to ctypes 0.6.

> I installed readline.

Which one?  The unc-readline, from:

http://sourceforge.net/projects/uncpythontools

is the only one that works correctly.  The one here:

http://newcenturycomputers.net/projects/readline.html

is terminally broken, don't use it.  It's not a real readline, it misses 
critical parts of the api.

Will this involve anything beyond deleting the ctypes folder
and then installing 0.6?

That's the one I used.

you mean:

    import Gnuplot
    g=Gnuplot.Gnuplot()

Every 

    g=Gnuplot.Gnuplot()

kills the current wgnuplot.exe (I'm working on WinXP) as well as the current
plot window and starts a new gnuplot session (new wgnuplot.exe). The problem
is that I want to keep the former plot windows (I want them to appear one
after the other).

I just installed the old one over the new one and it worked fine.  ymmv.

Fernando,  maybe you should put a note on the web site about this.  I did a
new install on a new machine and was quite puzzled for a while...

I suppose so, but you'll have to give it a try.  Best,

f

gplot documentation

List,

Im new to using Scipy and was wondering where to look for 
documentation on gplot. Ive looked at the gnuplot webpage but havent 
found any sections that resemble the functions in the plotting 
tutorial. 

Thanks,

Jeremy

Biggles rocks.  It is a big more object oriented if I remember, compared 
to the others.  The only problem is no one has built biggles for windows 
with python 2.3, so in my opinion it is not cross-platform.  I have no 
idea if further windows packages will ever be built for future python 
versions so that's why I stay away from it as a long term solution.  I 
love the graphs it produces and it is very fast.
