Ridgeline Plot

A ridgeline plot stacks a series of partially overlapping density curves, one per group, so a viewer can compare distribution shapes across many categories in a small area. It is a compact alternative to a row of histograms or violins, ideal for showing how a metric shifts from w

When to use this template

A ridgeline plot excels at revealing how the distribution of a quantitative variable evolves or differs across numerous ordered categories. Analysts use it to quickly spot shifts in central tendency, spread, skew, or multi-modality, making it ideal for tracking changes in a metric over time or across distinct groups. It provides a holistic view of distributional trends that would be cumbersome to discern from many separate charts.

  • Datasets with a single continuous quantitative variable.
  • Data grouped by a high-cardinality ordinal or categorical variable.
  • Comparing distribution shapes across 10-50 distinct groups.
  • Observing subtle shifts in distribution over time or ordered categories.
  • Identifying trends in skew, spread, or modality across groups.
  • When space is limited for comparing many individual distributions.
