Hi all,
The attached is a proposal for a new external template for gnuplot, a
graph plotting program. I have been using it for my personal use for a
while, but I thought it may be better included in the main body as it is
convenient.
With this template, users can directly edit the gnuplot source code from
lyx, whereas its consequent graphics is automatically included in outputs.
Although the attached script can generate other graphics formats as
well, in the purpose of external template, it is only used for
generation of an EPS graphics file from a gnuplot source code. If
necessary, users can add additional converters for each graphics format.
I think it should be better checked by professionals, but I hope it is
useful.
How do you think?
Best regards,
Koji
