Dual Axis & Combined Axis Charts

Reading Time: 8 Mins | Level: Beginner to Advanced

1. When to Use Dual Axis Charts

A Dual Axis Chart overlays two independent measures on the same visual canvas with separate y-axes (left and right).

• Classic Use Case (Combo Chart): Plotting Sales (Volume - Bars) on the left axis and Profit Margin % (Rate - Line) on the right axis over time.

2. How to Build a Dual Axis Chart:

1. 1
   Drag Measure 1 (Sales) and Measure 2 (Profit) onto the Rows shelf (creates two stacked charts).
2. 2
   Right-click the second measure pill on Rows $ o$ Select Dual Axis.
3. 3
   CRITICAL STEP: If both measures share the same unit (e.g. INR), right-click the right axis $ o$ Select Synchronize Axis!
4. 4
   Customize mark types independently in the Marks card (e.g., Bar for Sales, Line for Profit).
