[Gnuplot-info] Calling gnuplot from csh shell

[Eduard <edu...@ya...>]

 Hi All,
 
I am a new user of Gnuplot and I have a basic question.
I want to write a script in csh (c shell) which takes some data from a file
named output.dat and sends it to gnuplot for plotting (a 2D plot). The
output.dat file has 3 columns -x,y,z. I am interested to plot (y+z) as a
function of x. What I did is the following:
________________________________________________________

#!/bin/csh

set IN  = ./output.dat
set OUT = ./output.eps
cat <<EOF | gnuplot > $OUT
set term postscript eps color
set origin 0.0,0.5
set size 0.5,0.5
plot "$IN" u 1:(2+3) title "p"  with lines
EOF
--------------------------------------------------------------------------------------
The bolded line is the one which make me  difficulties. I have tried to
replace the syntax from -> 1:(2+3) <-
with 1:($2+$3), 1:$(2+3), etc but without any success :(. 

If you could help me to fix this problem it would be really great.

With all the best wishes,
Ed
