Live plots show a data-stream real-time, captured from a sensor, some process, I got that working, and you can read the related posts here: Matplotlib (not fast enough) PyQtGraph (better but still not fast enough) OpenGL (good, but I did not find how to use it in 2D efficiently, using subplots, titles, legends) Bokeh (good, but the scatter plots "blink" each time their particles turn color. It is intended for use in mathematics / scientific / engineering applications. This tutorial will compare Plotly and Matplotlib to help you decide which library to use for your specific needs.
