This is a ready-to-run example for implot-go using a modified backend from github.com/inkyblackness/imgui-go-examples, namely the GLFW/OpenGL3 one. It has been modified for my own use and was ripped out of a larger project, so there are some other random packages kept together with it.
Surely enough you can take any backend/renderer combo from imgui-go-examples and add ImPlot code to it, or write your own. Things should work out of the box for ImPlot, at least with the current way Go links C libraries.
Just type go run . to run the example.
The file example.go should interest you the most housing example Go code for the ImPlot-Go window.
