This paper presents an in-depth technical analysis of automatic inline label placement for Matplotlib line plots. Addressing the limitations of manual annotation methods that require tedious coordinate specification and suffer from layout instability during plot reformatting, we propose an intelligent label placement algorithm based on potential field optimization. The method constructs a 32×32 grid space and computes optimal label positions by considering three key factors: white space distribution, curve proximity, and label avoidance. Through detailed algorithmic explanation and comprehensive code examples, we demonstrate the method's effectiveness across various function curves. Compared to existing solutions, our approach offers significant advantages in automation level and layout rationality, providing a robust solution for scientific visualization labeling tasks.
