Matplotlib <https://matplotlib.org/> is the standard Python plotting library, and it has GUI backends (Tk, Qt, Gtk, ...) that should be perfectly suitable for your purposes. The API maybe takes some getting used to, but there are plenty of examples to be found around the web, and the main documentation is quite good. If you need the plots to update quickly (it doesn't sound like it) then you might need to luck into something else, like pyqtgraph or vispy. -- Thomas Jollans -- https://mail.python.org/mailman/listinfo/python-list
