Area Bump

See how rankings and category dominance change over time with the Area Bump Chart Viz Extension. This extension builds stacked area charts where categories are re-ordered at each time point by their value, so you can spot rank changes, leadership shifts, and evolving positions directly in your Tableau dashboards.

Whether you’re comparing brands, products, regions, or teams over time, the Area Bump Chart turns temporal ranking data into a clear, flowing view of who’s on top, who’s rising, and who’s falling without losing the sense of magnitude that stacked areas provide.

Ranking data over time tells a story of competition and change, but standard charts often hide that story in tables or separate line charts. The Area Bump Chart Viz Extension combines stacked areas with dynamic re-ranking: at every time step, categories are sorted by value and stacked, so band order and thickness reflect both rank and size. The result is a single, readable view of dominance, rank swaps, and trends.
