Matplotlib - Interactive Features

You wrote this code but the zoom and pan buttons do not appear in the plot window:

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.show(block=False)

What is the likely reason?

AYou forgot to call <code>plt.enable_toolbar()</code>

BUsing <code>block=False</code> can prevent the toolbar from showing properly

CZoom and pan buttons are not available for line plots

DYou need to call <code>plt.show()</code> twice

Step-by-Step Solution

Solution:

Step 1: Understand block=False effect
Using plt.show(block=False) can cause the plot window to not fully initialize, hiding toolbar buttons.
Step 2: Check other options
No plt.enable_toolbar() function exists; zoom and pan are available for line plots; calling plt.show() twice is unnecessary.
Final Answer:
Using block=False can prevent the toolbar from showing properly -> Option B
Quick Check:
block=False may hide toolbar [OK]

Quick Trick: Avoid block=False to ensure toolbar shows [OK]
