Visualizing Panel Data: Creating Separate Histograms for Different Years Panel data refers to datasets that contain observations over multiple periods or units, often with time-series components. In this post, we’ll explore how to create separate histograms for different years in panel data using the ggplot2 library. Introduction Panel data provides valuable insights into how variables change over time, allowing us to identify trends, patterns, and relationships between observations. However, when dealing with large datasets containing multiple years of observation, it can be challenging to visualize the distribution of a variable across different periods.
