Cannot open a .dat file to plot !! :(

[Phass <pha...@gm...>]

Hi all !  I'm doing my final degree project and I've got to make some
graphics with gnuplot. Im doing it in c++ and I create pipes to call gnuplot
in my program. 

Problem is that the user defines the route where the points to plot are, but
where i insert the plot command, the .dat file defined in the route is not
recognized and I don't know how to solve it.

thanks to all
