Click here Cursor Demo. import numpy as np import matplotlib.pyplot as plt from matplotlib.widgets import Cursor Install Matplotlib. Within the function, a global variable called coord is defined, this is done in order to store the values generated within the function and to have them available also in the coord variable outside the function. The function takes as input the axes in which we want to display the cursor (ax in this case) and other properties of the cursor itself; namely horizOn and vertOn, which generate an horizontal and a vertical line that univocally identify the cursor while it is hovering on the plot; their value can be set to True or False, depending on how we want to identify the cursor. Different methods of using matplotlib in notebooks: Option 1: Use %matplotlib notebook to get zoom-able & resize-able.
