Matplot / ImPlot 📈

Various lib for plotting from c++, ruby or python - Matplotlib / github / wikipedia

Ruby

Matplotlib - enables to directly call matplotlib from Ruby language. This is built on top of pycall.

ImGui / C++

ImPlot

A 2D immediate mode, GPU accelerated plotting library. - online demo

see also

ImPlot Demos - demos here are more sophisticated than those provided in implot_demo.h, and may rely on third-party libraries that would otherwise clutter ImPlot’s main repository.

Using as meson wrap-git with GLFW + ImGui (+ SKIA)

**Notes** - Meson **merge together git clone+patch once** when issuing `$ meson setup build .` - afterwhat modifying subprojects/packagefiles/implot/meson.build won't be taken into account - you need to delete `subprojects/implot` and do the setup again to make it happen. - or run (?) [`meson subprojects update`](https://mensinda.github.io/meson/Subprojects.html#update-subprojects) update your project _meson.build_

implot_dep = dependency('implot', fallback: ['implot', 'implot_dep'])
implot_sources = subproject('implot').get_variable('implot_sources')

# Example executable
executable('my_app',
  sources,
  implot_sources,  # 👈 add implot sources to your build
  dependencies: [implot_dep],
)

[And into your imgui code](https://github.com/epezent/implot?tab=readme-ov-file#integration)

ImGui::CreateContext();
ImPlot::CreateContext();   // Create and destroy an ImPlotContext wherever you do so for your ImGuiContext

To test it, you can add call `ImPlot::ShowDemoWindow()` somewhere in your update loop.
