Dual Axes

You can compare multiple measures using dual axes, which are two independent axes that are layered on top of each other. Dual axes are useful when you have two measures that have different scales. To add the measure as dual axis drag the field to the right side of the view and drop it when you see a black dashed line. You can also select Dual Axis on the field menu for the measure.

The result is a dual axis view where the Profit axis corresponds to the purple line and the Shipping Cost axis corresponds to the brown line.

You can add up to four layered axes: two on the Columns shelf and two on the Rows shelf.
To align the two axes in a dual axis up, right-click the dual axis and select Synchronize Axis.
