Thanks.
I installed "gd" from the Libs category and everything works.
There was nothing in the README.Windows file to suggest this - see below.
BTW: To use this version of Gnuplot with Octave, I only had to add the line
gnuplot_binary = 'gnuplot'
to /usr/share/octave/site/m/startup/octaverc
I didn't need 'pipe-gnuplot' or 'pgnuplot' as described in
http://octave.sourceforge.net/Octave_Windows.htm#Step6
Ben.
README.Windows:
This is gnuplot version 4.0 -- binary distribution for MS-Windows 32bit
with Cygwin and X-server
==========================================================================
Ignore this package if you don't know what X11, X-server and Cygwin means.
In short, it contains unixish-like gnuplot executable for command line and
with X11 terminal -- that's what you search for if you need multiple
interactive graph windows.
For example, "set term x11" allows you to use the figure(n); commands in
Octave (www.octave.org) even under Windows.
This distribution was obtained by the unixish way of compilation under
Cygwin:
bash
./configure
make
make install
Binaries included:
------------------
* gnuplot.exe: The gnuplot executable for Windows with x11 terminal.
Installation
------------
* Unzip this package into Cygwin directory, e.g. C:\cygwin.
Then, you should find gnuplot.exe in Cygwin's /usr/local/bin directory,
and similarly for other files.
* See 'help start', 'help environment' etc. for setting up your environment,
if not already done for the usual gnuplot for Windows.
* No additional documentation is included. Please use the usual gnuplot 4.0
Windows binary distribution package which contains complete set of
README's, INSTALL's, demo/, docs/, etc.
Running
-------
* Run X-server, for example
- Cygwin-X11 (free, www.cygwin.com/xfree/) -- command "startxwin.bat"
- Small stripped version of the above -- search web for file XFry86.zip
- Any other free X-server
- Any shareware or commercial, like eXceed, X-Win32, X-ThinPro,
Astec-X,...
* Set DISPLAY environmental variable to your machine
* Run gnuplot.exe and enjoy "set term x11" with its multiple graph windows
