Open questions for inclusion into the FAQ?

[Johannes N. <nen...@as...>]

hello,

sorry, these are only questions, without answers.

1) is it possible to define similar to defining strings (filnam =
"file1.dat"), similar to defining numerical variables (n = 3) ?

2) is it possible to use different columns from different files in one plot:
   plot "file1.dat" u 3 : "file2.dat" u 2

3) is it possible to create multi-page postscript output?


regards,

john

There's one too many "similar to" in that sentence, but yes, this is 
possible.  So far only in the development version though.

No.  For that, use external file proceessing tools, e.g.

	plot "<paste file1.dat file2.dat" u 3:5

Yes.  Just leave terminal, output and multiplot alone, don't use the 
'eps' option, and sequence of plots will end up each on a page of its own.

Yes, but only in version 4.1

No.  
However, depending on the file formats it may be possible to
merge the files into one stream as you go:
	NCOLS = 3
	plot "join file1.dat file2.dat" using 3:(NCOLS+2)

Of course. Every plot gets a new page. Surely you tried this?
