Stacked Area

Multiple area series stacked on top of each other to show how individual parts contribute to a total over time. The top edge represents the cumulative sum, while each colored band shows one component's share.

Best for

  • Showing how components contribute to a total over time
  • Visualizing shifts in composition across periods
  • Displaying both individual trends and cumulative totals

Avoid when

  • Individual series values are more important than the total — overlapping areas mislead
  • There are many series with similar values — bands become too thin to read
  • Precise comparison between series is needed — use grouped line charts instead
