A stacked Step Area Chart combines step-line geometry with stacked filling, connecting data points via horizontal-then-vertical segments. This emphasizes discrete period-to-period changes rather than implying smooth transitions, which is well suited for annual or categorical data.
This sample breaks down yearly comment statistics into three sentiment categories -- Grateful, Neutral, and Disgruntled -- stacked to show both each category and the cumulative total. A crosshair highlights all series at the hovered year, and the legend lets you toggle individual sentiment bands on or off.
