Read Original

This article addresses a common problem in R's ggplot2 where line charts render as blank with a warning about groups having only one observation. It provides a step-by-step tutorial using simulated data to diagnose the issue, which often occurs when using categorical variables on the x-axis without proper grouping. The post includes code examples and solutions to create correct visualizations.
