[Gnuplot-info] GNUPLOT and plotting from files

[<ab...@dc...>]

Hi

I seem to be having problems of plotting data from a file for instance
when i do:

plot "plot.dat" using 2 t col, '' using 3 t col, '' using 4:key(1) t col;

This works!! But i need the commands and plotting data in one file as this
file is being transmitted over a network, so i did the following:

plot "-" using 2 t col, ' ' using 3 t col, ' ' using 4:key(1) t col;

CLASS FLOWS PACKETS BYTES
WWW 0.42857142857142855 0.7923076923076923 0.9423913771172256

FTP-CONTROL 0.0 0.0 0.0
FTP-PASV 0.0 0.0 0.0
ATTACK 0.0 0.0 0.0

But this only displays the FLOWS columns results and not the other two. I
understand that the error states it could not open the file ''. But i
would be grateful if you could help resolve my problem.

Thanks in advance
