gnuplot is then called to run a file named data_t which is located in the same folder as the Fortran program. The above Fortran program actually calculates the points on the parabola y=x^2 and then writes into the file data. Once gnuplot finishes plotting (to your display/ or to a file), then the control will be given back to the Fortran program to continue execution. So what has it got to do with Fortran programs? Since gnuplot can be run from a terminal, we can ask the Fortran program to open a system terminal and ask to run gnuplot. Instead, a program is typed and saved with an editor (i.e., a word processor), and the program is then turned into an executable file by a Fortran compiler. It is a command line plotting utility that can produce publication-quality plots. Unlike in Basic, a Fortran program is not typed in a 'Fortran window'. While efforts are made to keep it up-to-date, it might not accurately reflect the status of the most recent GNU Fortran compiler.

#Simply fortran not recognized command how to#
Then I came across the wonderful gnuplot software (free and open source !!). This manual documents the use of gfortran, the GNU Fortran compiler.You can find in this manual how to invoke gfortran, as well as its features and incompatibilities. How great would it be if we can have a plotting option directly in Fortran programs? I was having trouble finding a proper way to do this.
