A side-by-side bar chart

A side-by-side bar chart can also be thought of as a stacked bar chart with a zero base. However, it is more accurate to describe it as a simple bar chart with dual horizontal axes. The reversed scales are used to indicate the magnitude. The direction of the bars is also reversed. A side-by-side bar chart still conveys the same information as a simple, stacked or grouped bar chart but unfamiliar users may misinterpret it.
