Matplotlib - Seaborn Integration

Aimport matplotlib.pyplot as plt import seaborn as sns sns.violinplot(data=[1,2,3,4,5]) plt.axvline(x=2, color='red') plt.show()

Bimport matplotlib.pyplot as plt import seaborn as sns sns.violinplot(data=[1,2,3,4,5]) plt.axhline(y=2, color='red') plt.show()

Cimport matplotlib.pyplot as plt import seaborn as sns sns.violinplot(data=[1,2,3,4,5]) plt.axline(x=2, color='red') plt.show()

Dimport matplotlib.pyplot as plt import seaborn as sns sns.violinplot(data=[1,2,3,4,5]) plt.vline(x=2, color='red') plt.show()

Step-by-Step Solution

Solution:

Step 1: Identify the correct Matplotlib function
To add a vertical line, plt.axvline() is used.
Step 2: Check parameters
plt.axvline(x=2, color='red') adds a vertical red line at x=2.
Step 3: Verify other options
plt.axhline adds horizontal line; plt.axline and plt.vline do not exist or are incorrect.
Final Answer:
import matplotlib.pyplot as plt import seaborn as sns sns.violinplot(data=[1,2,3,4,5]) plt.axvline(x=2, color='red') plt.show() correctly adds a vertical line at x=2.
Quick Check:
Vertical line = plt.axvline [OK]

Quick Trick: Use plt.axvline for vertical lines, plt.axhline for horizontal [OK]
