legend in matplotlib
A legend in matplotlib is a small box that shows what each color or marker in a graph represents. It helps the reader understand the information being presented in the graph by providing a key or legend for reference. Imagine you are playing a video game and you see different symbols on the map – a star, a heart, and a diamond. The legend would tell you that the star represents a treasure, the heart represents health, and the diamond represents a weapon. This way, you know what each symbol means without having to guess. In a graph, the legend might show that a blue line represents sales in January, a red line represents sales in February, and a green line represents sales in March. This makes it easier for the viewer to interpret the data and understand the trends over time. A verifiable fact is that matplotlib is a popular Python library used for creating visualizations and graphs, including legends to help interpret the data.
