This project is a thin wrapper over System.Diagnostics.Process to 'easily' interact
with Gnuplot from F#.There are a couple of examples in the test\ directory.
Mostly it is few helper functions and a custom operator |>> that takes a string as an argument.
It expects regular Gnuplot dsl. So no need to learn a new library, only regular gnuplot dsl!!

Gnuplot(false, false, Some "Cp_fixed.png")

|>> "plot $vs using 1:2 title 'C_P approx' with lp lc rgb 'black' ,\\"
|>> "$vs using 1:3 title 'C_P analyt' with lp lc rgb 'blue'"
