Time-Dependent Graphs
Robert I. Kabacoff · 2024
A graph can be a powerful vehicle for displaying change over time. The most common time-dependent graph is the time series line graph. Other options include dumbbell charts, slope graphs, area charts, and steam graphs. A time series is a set of quantitative values obtained at successive time points. The intervals between time points (e.g., hours, days, weeks, months, or years) are usually equal.
