Time and Longitudinal
Start here for figures about change across time or another ordered axis, especially when the main question is how values progress from one position to the next.
Start here
Use this section when your figure question is about change across time, dose, passage, or another ordered x-axis where the progression from one point to the next is part of what you want readers to see.
This branch covers ordered-progression figures, not distribution-first group comparison, relationship-first association figures, or repeated measures statistical modeling.
If your main question is about group differences or distribution shape, go to Distribution and Group Comparison. If your main question is about association between variables or fitted trends, go to Association and Regression.

Scope notes
- This category is for figures that show ordered progression in the data.
- It does not decide whether your repeated-measures design needs a paired test, mixed model, or another repeated-measures-aware method.
- Common terms in this branch include timepoint, longitudinal data, ordered category, date axis, dose, and repeated measures.
Before you read further
- Read Line Chart if you want to summarize means or observations across an ordered sequence.
- Read Repeated Measures and Mixed Models if your main decision is analytical rather than graphical.
