When to use it
- Use it when a set of measurements can be split into discrete and comparable groups, to show the relative change between these groups.
- Use it when there are multiple sets of measurement groups, to show the relationship and change within and between groups.
- Use it, rather than a Line Graph, to display discrete quantities rather than continuing change.
- Use it, rather than a Pareto Chart, when a consistent ordering of bars is wanted. This can ease recognition and comparison of current and previous charts.
