[Solved] Given this code snippet:import matplotlib.pyplot as plt from matplotlib.widgets import Slider fig, ax = plt.subplots() plt.subplots_adjust(bottom=0.25) ax.plot([1, 2, 3], [1, 4, 9]) slider_ax = plt.... | Matplotlib

Matplotlib - Interactive Features

Given this code snippet:

import matplotlib.pyplot as plt
from matplotlib.widgets import Slider

fig, ax = plt.subplots()
plt.subplots_adjust(bottom=0.25)
ax.plot([1, 2, 3], [1, 4, 9])
slider_ax = plt.axes([0.25, 0.1, 0.65, 0.03])
slider = Slider(slider_ax, 'Scale', 0.1, 2.0, valinit=1)
plt.show()

What does the slider do?

AIt resets the plot to original data

BIt changes the color of the plot line

CIt allows changing the scale of the y-values interactively

DIt zooms the plot horizontally

Step-by-Step Solution

Solution:

Step 1: Understand Slider widget purpose
The slider is created with label 'Scale' and range 0.1 to 2.0, suggesting it controls scaling.
Step 2: Analyze code for slider effect
Though the code snippet does not show slider event handling, the slider is intended to adjust y-values scale interactively.
Final Answer:
It allows changing the scale of the y-values interactively -> Option C
Quick Check:
Slider purpose = Change y-scale interactively [OK]

Quick Trick: Sliders usually control parameters like scale or thresholds [OK]

Common Mistakes:

Assuming slider changes color without code support
Thinking slider zooms plot without zoom code
Believing slider resets plot data
