I want to try passing data to GNUPLOT from Fortran. The brute force method is to have my Fortran program write text files, exit the Fortran program, start GNUPLOT and read in the text files. Is there a way to start the GNUPLOT program directly from the Fortran program as a separate process in a new window? Can someone describe how this is done or point me to an example of this? Thank you.
To simply run GNUPLOT from your Fortran program you can use EXCUTE_COMMAND_LINE which is standard Fortran https://software.intel.com/en-us/node/692784 I have no idea about data transfer to it as I know nothing about GNUPLOT
