What are small multiples good for?
Small multiples are best used when representing simple visualizations that include a small number of dimensions. Because small multiples are used to compare differences across visualizations, the visualization type used and the data compared should be consistent across the entire series of visualizations.
What should small multiples have that enable different charts to be quickly compared?
Let's underline here: small multiples must have the same axes, use the same chart, be the same size, and show the same measures. The must be simplified and logically ordered.
Which chart type should never have a broken axis?
The one time you shouldn't break an axis is when making a bar or column chart because it breaks the relationship between the rectangle's dimensions and the data.
