I have had a similar problem. (I was not sure it is a problem so I
have not asked). When I try to compile a GNUPlot script in the
editor, I get lots of dings with no plot. However, if I save the
plot commands to a session icon and then right click the icon and
choose display it works like a charm.
Here is an example that will not compile (also I have attached the
data and session file). Note that if you leave the first line
commented out the script will compile, but ignores the change in
size.
The gnuplot script below looks fine, except that you're not specifying
where the output should go -- and by default the binary PNG bytes will
be spewed onto stdout, with results that probably won't be pretty.
After "set term pngcairo..." you should add something like
set output '/path/to/file.png'
or if you want to see the plot on-screen, select an interactive
terminal, e.g. "set term wxt" or "set term windows".
