Thanks for your advice,
It seems that keeping my plots in ps format will be a
much better plan as they keep all the detail. Now all
I need is a working script for converting them when
necessary.
cheers,
Lee -S-
PS. Changing the gset to:
gset terminal png large color;
only makes the fonts larger, the image remains at 640
x 480, while the graph is all squashed up by the huge
text.
As for Gnuplot, I have:
"Version 3.7 patchlevel 3
last modified Thu Dec 12 13:00:00 GMT 2002"

Since it is your gnuplot that does all the dirty work
here it is more interesting which gnuplot version you
are using, which terminals it has compiled in etc,
etc...
I usually recommend (and do it myself) to save plot in
postscript format and then use all powers of
ghostscript to convert the saved file to anything (or
almost anything) else.

If you start gnuplot directly and type "help set
terminal png", it will display the options that are
accepted. In this case,
~ Syntax:
~ set terminal png {small | medium | large}
~ {transparent | notransparent}
~ {monochrome | gray | color}
~ {<color0> <color1> <color2>
...}
So you probably want to try 'gset terminal png large'.
