Dual Axis Chart

A chart that overlays two measures with independent axes on the same pane, often with different mark types.

Definition

In Tableau, right-click the second measure and choose Dual Axis, then synchronize axes if they share units. Power BI's equivalent is the line-and-column combo chart. Mismatched scales can mislead viewers.

Exam tip

Synchronize axes when both measures share the same units.
