OpenGL ES support for hardware-accelerated plotting

[James Ross-Smith]

G'day,

I'm developing an embedded product, which is using the Raspberry Pi for prototyping. I've spent considerable time trying to get a real-time data plotting component of my PyQt5 application working. I've tried blitting with Matplotlib, PlotWidgets with PyQtGraph, and basic plotting examples with VisPy. I've managed to build the exact plots I want using each of these platforms on my Windows 7 machine, but am not able to get them working on my Raspberry Pi 2 (running Raspbian Lite). Matplotlib blitting and PyQtGraph seem to be raster-based, so were locking up the GUI with <1Hz refresh, whilst VisPy doesn't run at all, as it can't seem to find the required OpenGL information.

Has anyone else had any success with hardware-accelerated plotting on the RPi? I'm fast approaching the point where I'm going to have to rethink this entire project, so any input/guidance/advice would be greatly appreciated!

Cheers,

Jamie
