easy_plplot is a wrapper for PlPlot inspired by the interface of matplotlib. It is intended to fill the need for rapid feedback while developing numerical simulations, and does not replace more sophisticated packages such as matplotlib or even direct use of PlPlot.

While it is possible that the output from easy_plplot may be considered as publication quality, no assertion is made along those lines. This software has been written in the hope that it will be useful, especially for students in numerical analysis courses based on Fortran.

Documentation can be found here.

The following combinations are supported:

• Plplot 5.15.0
• libgd 2.3.2
• Fortran-lang/fpm 0.5.0

PS: It seems that the plplot-fortran of the debian and ubuntu distribution warehouses does not take into account the *.mod files, so it is best to use cmake to install plplot by yourself.

pacman -S <arch>64/mingw-w64-<arch>-x86_64-plplot pacman -S <arch>64/mingw-w64-<arch>-x86_64-libgd

Fortran Package Manager (fpm) is a package manager and build system for Fortran.
You can build easy_plplot using provided fpm.toml:

export FPM_FFLAGS="-Ipath/to/plplot/include" fpm run --example --all

To use easy_plplot within your fpm project, add the following lines to your fpm.toml file:

[dependencies] easy_plplot = { git="https://github.com/zoziha/easy_plplot" }
