A 100% stacked Area Chart normalizes every category to 100%, so each colored band shows the proportional share rather than the absolute value. This makes it ideal for comparing how the composition of a total changes across categories or time periods.
This sample visualizes regional cosmetic-product sales (USA, China, EU, and Africa) across nine product categories. A crosshair and union tooltips display all regions at once, while the interactive legend lets you toggle any region on or off -- and the remaining series automatically rescale to fill 100%.
Follow the step-by-step Area Chart Tutorial to learn how such charts are built. See the Area Chart documentation for all configuration options.
