A 100% stacked area chart where each series shows its relative percentage at each point. Best for highlighting how proportions shift across categories.
When to use a Line stacked percentage chart

-
Compare how distributions shift over time or between groups, regardless of total values.
-
Focus on relative trends rather than absolute numbers.
-
Visualise part-to-whole relationships in a smooth, continuous format that highlights changes in share.

💡 Tips for Line stacked percentage chart
-
Best for showing proportional change over time: Each point on the x-axis adds up to 100%, letting you focus on how the composition shifts.
-
Use when group sizes vary or totals aren’t important: Hides the overall magnitude to help emphasise relative changes.
-
Use contrasting colours for clearer segment separation: Distinct, high-contrast colours improve readability, especially when many segments are close in value.
