Fixing Chinese Character Display Issues in Data Analysis

If you are using matplotlib for data analysis, charts, or graph generation and notice Chinese characters rendering as missing blocks or boxes, add the following configuration line to set a supported CJK font:

import matplotlib.pyplot as plt

# Set supported Chinese font for matplotlib
plt.rcParams['font.sans-serif'] = ['WenQuanYi Zen Hei']
plt.rcParams['axes.unicode_minus'] = False  # Resolve minus sign display issue

Instruct your Data Analyst agent (@David) to include this font setup in all data visualization scripts.
