This article provides an in-depth exploration of how to add legends to multi-line graphs using the ggplot2 package in R. By analyzing a common issue—where users fail to display legends when plotting multiple lines with geom_line()—we explain the core mechanism: color must be mapped inside aes(). Based on the best answer, we demonstrate how to automatically generate legends by moving the colour parameter into aes() with labels, then customizing colors and names using scale_color_manual(). Supplementary insights from other answers, such as adjusting legend labels with labs(), are included. Complete code examples and step-by-step explanations are provided to help readers understand ggplot2's layer system and aesthetic mapping. Aimed at intermediate R and ggplot2 users, this article enhances data visualization skills.
