html - gnuplot giving warning: Skipping data file with no valid points -

i using gnuplot script

#qe.conf set terminal png truecolor set output "qe.png" set xrange ["400" : "700"] set yrange ["0" : "1"] set style info lines plot "qe.txt" using 1:2 title "%red", '' using 1:3 title "%g-r", '' using 1:4 title "%g-b", '' using 1:5 title "%r"

i executing gnuplot script qe.conf through shell script gives me next error

gnuplot> plot "qe.txt" using 1:2 title "%red", '' using 1:3 title "%g-r", '' using 1:4 title "%g-b", '' using 1:5 title "%r" ^ line 0: warning: skipping info file no valid points

gnuplot> plot "qe.txt" using 1:2 title "%red", '' using 1:3 title "%g-r", '' using 1:4 title "%g-b", '' using 1:5 title "%r" ^ line 0: warning: skipping info file no valid points

gnuplot> plot "qe.txt" using 1:2 title "%red", '' using 1:3 title "%g-r", '' using 1:4 title "%g-b", '' using 1:5 title "%r" ^ line 0: warning: skipping info file no valid points

`

can suggest solution?

hi all, after hours of trying still dont have answer. tried next things. tried giving absolute paths datafile, gnuscript , shell script. command gnuplot qe.conf works fine if run linux command prompt when run through shell script gives error.

line 10: warning: skipping info file no valid points

request help.

the problem here you're trying plot 3rd, 4th, , 5th columns of 2 column dataset. if alter plot command drop that's using 1:3 or higher, should work fine. error message telling info file empty (in higher columns).
