Calling Gnuplot from FORTRAN

**Abraham** · Nov24-09, 07:25 PM

hello. I have a fortran code that has data points as output.

How do I get fortran to plot these data points using gnuplot?

Is there a way to call the external program from within fortran?

I am using fortran95, gfortran compiler. I'm on a windows machine, but
I'm connected remotely to the Unix machines in the lab.

Thanks,

Abraham

Hi Abraham,

Try using the "system" subroutine.

Code:

CALL SYSTEM(gnuplot )

Whatever you put inside the parentheses gets passed to the command line (or terminal depending on your os.)
