@rougier hey there, #PyQtGraph maintainer here! I'm taking a look at #GlumPy and I'm curious if you think there is room for collaboration. GlumPy seems to address a couple of issues that PyQtGraph is really struggling with, OpenGL and Non-Linear transformations. That said, we're very embedded into the Qt framework, so it may not be feasible to integrate more closely.
Also thank you so much for putting up OpenGL resources on your README!
