I have to plot with Gnuplot the data contained in 3 CSV files.
Commonly, I use the following code to plot from 2 CSV files:
$datablock << EOD `cat ../Q1a/sim_Q1.csv <(tail -n+8 ../Q1b/sim_Q1.csv | tr '",' ' ' | sort -nk19 )| tail -n+8 | tr '",' ' ' | sort -nk19 > ../Q1a/Q6_ressult.txt` EOD set print "|bash -x" print $datablock set print
The CSVs are in three different directories.
The data start at row 8, and I must take out the
, characters, and sort the data by column 19.
I do not know how to extend this code to paste 3 different CSV's doing the same,
tail -n+8 and
tr commands, and get a final
.txt file with the result.
