The update function is triggered by the slider's on_changed() event. import numpy as np import matplotlib.pyplot...

This can be usefull when you want to visualize incoming data in real-time. This data could, for example, come from a microcontroller that is continuously sampling an analog signal. In this example we will get our data from a named pipe (also known as a fifo). For this example, the data in the pipe ...
