The biggest issue I had with plot libraries is that they don't work out of the box for millions of data points. Last time I was doing a data science project, I tried all of the major plotting libraries and none of them works well beyond a few million data points. I want a graph that I can visualize and zoom in/out in real-time and that became the hard part of the project. Only one product claims to be able to handle it using GPUs in the cloud and it needs a paid subscription and uploading your data into the cloud. I don't want yet another library, but some library that works really well and can utilize local GPU for plotting.
