Dual axis chart

Dual-axis charts are used to show the relationship between two quantitative variables and a third categorical or date variable.

To create this type of chart, you must link the categorical variable to one of the axes, and the other two quantitative variables to the other axis.

Among the options specific to either of the two quantitative variables, you must check the "Dual Axis" option under "Position". In addition, you can select the type of mark linked to each axis in the "Custom mark" option.
