hi,
please can I ask you for some help? I have data from 3D situation, x y z value
I'd like to use gnuplot to generate maps of the value in the planes z=0 to z=1 for example, my file looks
like
-0,012 0,0060 0,0 0,13972813076023477
-0,012 0,0064319163 4,2894483E-4 0,1959584596359705
-0,011398672 0,00644576 0,0 0,20924591828425124
-0,012 0,0068638325 8,5788965E-4 0,19486370704346412
also 4 columns, usorted, delimited by tab
I know how to do it the staff with the gnuplot, the problem is: how to generate files from this one, each containing only those points in the z=0.5 +- 0.05 for example?
i would like to have files
0.txt 0.1.txt 0.2.txt 0.3.txt 0.4.txt 0.5.txt ....
so I would need to sort the file by the 3rd column and the cut it into smaller files with the approx. same number in the 3rd column...
I've tried (excerpt from the script)
sed -i 's/,/\./g' .temp
maxx=$(awk 'max=="" || $'$sp' >max {max=$'$sp'} END{ print max}' FS="\t" .temp)
minn=$(awk 'min=="" || $'$sp' < min {min=$'$sp'} END{ print min}' FS="\t" .temp)
i=$minn
while [ "$(echo "$maxx > $i" | bc)" -eq 1 ]; do
awk '{if ($'$sp' > '$(echo "$i - $plus" | bc -l)' && $'$sp' <=$i) print $0 > "'$name'/0'$i'"}' FS="\t" .temp
i=$(echo "$i + $plus" | bc -l)
done
but the files are not well, there is problem with the minus sign in the first column. Can you help me, please?
Thank you
