Description: Plot overlay is the process of displaying multiple graphs on the same axes, allowing for direct visual comparison of different data sets. This technique is particularly useful in data analysis, as it facilitates the identification of patterns, trends, and relationships between variables. By overlaying plots, analysts can observe how different data series behave in the same context, revealing valuable insights that might be overlooked if analyzed in isolation. Overlaying can be done with various types of visual representations, such as lines, bars, or areas, and can be applied across different disciplines, from economics to biology. However, it is crucial that the plots are clear and well-labeled to avoid confusion, as excessive overlaying can lead to visual overload. In summary, plot overlay is a powerful tool in data visualization that allows users to gain a deeper understanding of the information presented.
