However, except for the first series of data (next to the axis) it's more difficult to compare the relative size of the components that make up each bar. Also, as categories or data series are added, stacked column charts quickly become visually complex.
Multiple categories and data series in a compact space
Able to show change over time of category sub-components
Difficult to compare all but first series
Become visually complex as categories or series are added
