Dual Y-axes charts
A dual Y-axes chart summarizes or plots two Y-axes variables that have different domains.
For example, you can plot the number of cases on one axis and the mean salary on another. This chart
can also be a mix of different graphic elements so that the dual Y-axes chart encompasses several of
the different chart types. Dual Y-axes charts can display the counts as a line and the mean of each
category as a bar.
