Easy Plplot

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.

Getting Started

Supported Compilers

The following combinations are supported:

Name Vesrion Platform Architecture
GCC Fortran(MSYS2) 11 Windows 10 x86_64

Dependencies

Build Environment in MSYS2

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

Build with Fortran-lang/fpm

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" }

!> Create the project logo
program logo_prg
    use utilities_m
    use easy_plplot_m
    implicit none
    real(wp), parameter :: pi = acos(-1.0d0)

    call setup(device='svg', fileName='build/logo-%n.svg', figSize=[600, 500])
    call makeLogo
    call show()

contains

    subroutine makeLogo
        real(wp), dimension(:), allocatable :: x, y1, y2, y3

        x = linspace(0.0_wp, 1.0_wp, 100)
        y1 = x**2 - 1.0_wp
        y2 = 2.0_wp*x - 1.0_wp
        y3 = x
        y3 = cos(2.0_wp*PI*x)

        call figure()
        call subplot(1, 1, 1)
        call xylim(mixval(x), mixval([y1, y2, y3])*1.1_wp)

        call plot(x, y1, lineColor='b', lineWidth=1.2_wp)
        call plot(x, y2, lineColor='r', lineWidth=1.2_wp)
        call plot(x, y3, lineColor='c', lineWidth=1.2_wp)

        call ticks(lineWidth=1.2_wp)
        call labels('', '', '')
    end subroutine makeLogo
