Being honest, I plan to do that, but never achieve the openGL part, so Reply reply More In this case it sets hvplot / holoviews as the plotting backend: pd. Basic plot with embedded Matplotlib. Now the api is similar to WebGL. One could then quickly visualize huge datasets with the same commands than matplotlib. In fact, it is triggering a lazy initialization of the "backend" via importing pyplot under the hook, and I can imagine that creating some variations in behavior, since merely calling import matplotlib is not sufficient to trigger the initialization (at least in all cases). On Linux, for example, Qt is the only matplotlib backend for which 3D rendering will work correctly. use('TkAgg', force=True) import matplotlib. ToolManager (figure = None) [source] #. backend_pgf.
