How to Create a Gradient Radial Chart in Tableau for Stunning Visuals
Learn how to create a gradient radial chart in Tableau. This is possible by combining custom calculations that convert data points into radial positions, creating the circular layout. To add the gradient effect, I use a points bin on the Marks card, which allows you to assign colors to each segment of the radial chart. By applying one of Tableau’s color palettes, you can create a smooth gradient that enhances the visual appeal. This method is great for displaying data like category breakdowns or performance metrics with a visually engaging radial design.

Formulas:
Radial - Points: IF CONTAINS([Table Name], "1") THEN 0 ELSE 270 END
Radial LOD: {FIXED [Segment], [Metric]: AVG([Metric Value])}
Radial - Rank: RANK_UNIQUE(-SUM([Radial - LOD]))
Radial - X: SIN((INDEX()-1) * WINDOW_MAX(MAX(PI()))/180) * WINDOW_MAX([Radial - Rank])
Radial - Y: COS((INDEX()-1) * WINDOW_MAX(MAX(PI()))/180) * WINDOW_MAX([Radial - Rank])
