Hi Patrick, in the data file you've sent me there a comma works as a separator, so your data separator is set probably to ',' or ', '. Contrary to 'whitespace' separator, it does depend on the number of spaces in the second case and, moreover, table-print always put some extra spaces. So what to do.... Solution 1: Different format for both data-sources, as you've suggested: > set datafile separator "," > set table $DATA > plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3 > unset table > plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3, $DATA u 1:2 " %lf %lf" Solution 2: Put both separators to comma: > set datafile separator "," > set table $DATA separator "," > plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3 with table > # with table has not to be omitted > unset table > plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3, $DATA u 1:2 Solution 3: Put both separators to whitespace: > set datafile separator whitespace > set table $DATA > plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3 > unset table > plot "<tr , ' ' <070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3, $DATA u 1:2 Sincerely I.
