[Gnuplot-info] Solved: 'plot for' syntax

[Yanni <y.g...@ma...>]

Hello again

I think I got it. I removed the title bit in the "plot for" line and I 
got a nice looking graph.

Like this:

plot for [ no = 1 : words(files) ] word(files, no) u 2:3:1 w l lc palette

Thank you very much for pointing me to the right direction.

Hi Ivana

Many thanks for your reply. The result is all squeezed. This is my 
little script:

------------------------------------------------------------------------------

set term pdf
set output 'test.pdf'
set size square
set xrange [1:4000]
set yrange [1:4000]
set palette defined (0 "black", 1 "red", 2 "orange", 3 "green", 4 "blue")

files= system ("ls *.vec")
#files= "file.vec"

pointsize = 1.5

#plot for [ no = 1 : words(files) ] word(files, no) using 1:2 title 
'Flow'.no
#plot files u 2:3:1 w l lc palette

plot for [ no = 1 : words(files) ] word(files, no) using 1:2 title 
'Flow'.no u 2:3:1 w l lc palette

------------------------------------------------------------------------------

Before I found out about "plot for". I was plotting each file 
individually using:

plot files u 2:3:1 w l lc palette

If I try to add these parameters: (u 2:3:1 w l lc pallette) into the 
"plot for" syntax, in oder to get a better looking graph, gnuplot is not 
happy and gives me this error:

"gnuplotloop.script", line 15: unexpected or unrecognized token

Line 15 is the "plot for" line. Could you please let me know how can I 
add these parametes in the "plot for" syntax?

Thank you
