I’ve mainly encountered box-and-whisker plots being used to display results from scientific experiments in reports and papers. I have not seen them used on other dashboards. The histograms I have seen have mainly been in the setting of displaying grade distributions on examinations.
I think histograms are easy to understand at a glance. Box-and-whisker plots, however, are less immediately clear and require an explanation of what the box and “whiskers” represent. I think that once you know how to read them, they are useful for showing more information about the statistical distribution of the data.
