using gnuplot (wgnuplot) with octave under windows 95

[Alan Rockwood]

I am having trouble setting up wgnuplot to work with octave under windows 
(cygwin). I think my problem has something to do with octaverc.

Here's my batch file for starting octave. It's named octave.bat:

rem @echo off
rem :: ..generated by GNU Octave setup.bat, then modified by ALR
if not exist \tmp\nul mkdir \tmp
bash --login StartOctave
rd \tmp


OK now, that's the end of my batch file. StartOctave looks like this:

#!/bin/sh
rxvt -fn "Courier New-14" -tn linux -title "GNU Octave 2.1.31" -n "GNU 
Octave" +sr -sl 1000 -e octave


OK that's the end of StartOctave. So far, so good. Everything works fine. 
However, I have tried to hook octave to wgnuplot using pipe-gnuplot.exe and 
have not succeeded. I think it has something to do with the file octavert. 
This is how I set up the file octavert:

## System-wide startup file for Octave.
##
## This file should contain any commands that should be executed each
## time Octave starts for every user at this site.
gnuplot_binary = "pipe-gnuplot c:/gnu/usr/local/bin/wgnuplot"
putenv('TMPDIR','c:/PalmDev/cygwin/tmp')

The path pointing to wgnuplot is correct. I am not sure what the purpose of 
the putenv line is, but it does point to an existing directory.

I think the fundamental question is this: How does octave find octavert?

A related question is this: Should I put the lines that I now have in 
octavert into the file StartOctave, or possibly into the file octave.bat?

Thanks.
