Imgui-rs looks really good, thanks! Imgui does say it can output raw vertex buffers, so you could probably put imgui stuff in an egui gl frame and reskin egui

Imgui-rs looks really good, thanks! Imgui does say it can output raw vertex buffers, so you could probably put imgui stuff in an egui gl frame and reskin egui to match the looks. I've only kicked the wheels a bit on egui, but for plotting signals it seemed more than adequate. Its histograms looked fine too. The only thing I saw missing was 3d plotting and heat maps.
