Re: [Gnuplot-info] Plot a function in defined intervall

[Jon <dev...@gm...>]

Very instructive!

I would like to know more about using "+" as special filename, so I run help
plot and then choosing datafile for details, but I can only find explanation
for another special filename "-" but not "+", where can I get indepth
explanation for it?

This is actually a long-lasting question I had with gnuplot help. Gnuplot
uses very common words as command, which is easier for us to remember, but
also makes it much harder to get help through search engines like google.
Usually I have to spend time going through the help manual in details to get
what I needed.

Thanks,

Sincerely,
Jon
