[Gnuplot-py-users] Re: Gnuplot python question - using TempArrayFile instead of stdin

[Andrew S. <and...@ad...>]

It sounds good...  However, I just did a CVS checkout, build, and  
install and got the following:

 >>> import Gnuplot
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File  
"/Library/Frameworks/Python.framework/Versions/2.2/lib/python2.2/site- 
packages/Gnuplot/__init__.py", line 177, in ?
     from PlotItems import PlotItem, Func, File, Data, GridData
   File  
"/Library/Frameworks/Python.framework/Versions/2.2/lib/python2.2/site- 
packages/Gnuplot/PlotItems.py", line 374, in ?
     if gp.GnuplotOpts.support_fifo:
AttributeError: class GnuplotOpts has no attribute 'support_fifo'

(I'll dig farther, but this is what I got to tonight.)

Cheers!
Andrew
