[Solved] Consider the code below:import matplotlib.pyplot as plt fig, ax = plt.subplots() def on_move(event): print(f"Mouse at: {event.xdata}, {event.ydata}") cid = fig.canvas.... | Matplotlib

Matplotlib - Interactive Features

Consider the code below:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

def on_move(event):
    print(f"Mouse at: {event.xdata}, {event.ydata}")

cid = fig.canvas.mpl_connect('motion_notify_event', on_move)
plt.show()

What will happen when you move the mouse over the plot area?

AThe coordinates of the mouse pointer inside the plot will be printed continuously

BNothing will happen because the event is not connected properly

CThe plot will close immediately

DAn error will occur because <code>event.xdata</code> is undefined

Step-by-Step Solution

Solution:

Step 1: Understand the event type 'motion_notify_event'
This event triggers whenever the mouse moves over the figure canvas.
Step 2: Analyze the function on_move
The function prints the mouse coordinates inside the plot area using event.xdata and event.ydata.
Final Answer:
The coordinates of the mouse pointer inside the plot will be printed continuously -> Option A
Quick Check:
Mouse move event prints coords = B [OK]

Quick Trick: motion_notify_event tracks mouse movement over plot [OK]

Common Mistakes:

Assuming no output because event is not connected
Thinking event.xdata is always None or undefined
Expecting plot to close on mouse move
