Though both the reporting and Dashboard collections have Histogram components, another (perhaps overlooked) method of creating a histogram is to use the Generate Histogram component. In the enclosed example, histogram data are generated by category rather than for a whole dataset so that the final chart is color coded by a category of interest.

One feature this illustrates is that charting components can determine the number of data series dynamically. Here it would be unpleasant to create "Data Series X" parameter groups for each of 22 different makes of automobile, so instead 22 records that each have array data are piped to the Bar Chart component.
