Re: [Gnuplot-info] Plotting partial file based on 3rd column

[Mikhail K. <mko...@gm...>]

you could use external data processing in this case, like:

echo "plot \"< awk '{ if (\$3==\\\"A\\\") print}' data\" u 1:2 w l" | 
gnuplot --persist

it is possible to avoid ugly escaping by putting the processing commands 
into a separate shell script.
