I haven't actively been following the development of numarray, but I 
understand that it is almost identical to Numeric.  Does anybody know of 
any differences that would be relevant to Gnuplot.py?  Is it imported 
under a different name, or does one still "import Numeric"?

If Gnuplot.py would require changes to use numarray, then the most 
important question is when to make the transition.  It's unlikely that 
the whole Python community will switch from one library to the other on 
the same day!

Ideally, there would be a way to use Numeric and/or numarray and/or 
JNumeric or none of the above (native Python sequences).  There would 
need to be a way to decide which to use at the time that Gnuplot.py is 
imported.

Anybody have any thoughts on this issue?

Hi,
  Are there plans to update gnuplot.py to be compatible with numarray, 
which the Numerical Python website
says is to be the replacement for Numeric. I am fairly new to python, but 
if it is just a question of replacing
references to Numeric with numarray, I can probably handle it. Thanks for 
your assistance.

Hello,

I guess nobody has responded to this email?

I don't use windows, but I believe that this problem usually indicates 
that gnuplot (i.e., the program, not the Python interface) didn't start 
up correctly.  It could be a PATH problem, for example.  If you search 
the mailing list archives you will see several similar questions and 
responses.

Hello,

Thanks for Gnuplot.py!

The following is not a problem in 1.5:

>>> import Gnuplot
>>> g = Gnuplot.Gnuplot()
>>> g('test')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File
"C:\Python23\Lib\site-packages\Gnuplot\_Gnuplot.py",
line 199, in __call_
_
    self.gnuplot(s)
  File
"C:\Python23\Lib\site-packages\Gnuplot\gp_win32.py",
line 125, in __call_
_
    self.write(s + '\n')
IOError: [Errno 22] Invalid argument
>>>

Python 3.2.3
Numeric 23.1
Gnuplot.py 1.7
gnuplot 3.8j
win 2k
