Fortran does not automatically allow for plotting during execution. There is a work around. I touched on this with my previous post about plotting with gnuplot from python. The same principles apply here.
From fortran call gnuplot. For instance, to make a vector plot from fortran use the command
call system('gnuplot Vector.gp')
where Vector.gp is the gnuplot setup file for vector plotting.
This also requires a datafile that gnuplot can read. I prefer a csv file because I can put that directly into other programs like excel as well.
So what I've done, is built an IO module with several subfunctions that will create a datafile for gnuplot and call the system for me. More plot types are on the way. See attached for details.

By the way, I've switched to Atom text editor by github for my programming. The .gp files I included save as .png files so I can use them with both word and latex. Atom will open .png directly inside the editor and update as the figure updates. This is approaching an IDE and it's a lot faster to update the figure than with Windows Image Viewer. It should be a cross-platform solution too.
