fortplot

Fortran plotting with PNG, PDF, SVG and text output. The plotting core has no external graphics dependencies. Text output uses ASCII by default.

Install

fpm:

[dependencies]
fortplot = { git = "https://github.com/lazy-fortran/fortplot" }

CMake: (full template)

include(FetchContent)
FetchContent_Declare(fortplot

    GIT_TAG main)
FetchContent_MakeAvailable(fortplot)
target_link_libraries(your_target PRIVATE fortplot::fortplot)

The optional fortplot::fortarray target adapts labeled data_array_t values without adding plotting methods or state to fortarray:

use fortarray,          only: data_array_t, data_array
use fortplot,           only: figure_t, wp
use fortplot_fortarray, only: plot

type(data_array_t) :: field
type(figure_t) :: fig

field = data_array([2.0_wp, 3.0_wp, 5.0_wp], ["radius"], name="samples")
call fig%initialize()
call plot(fig, field)

CMake users can omit that dependency with -DFORTPLOT_BUILD_FORTARRAY_ADAPTER=OFF. fpm…
