 ### Histogram Sections {#histograms}
 
 The **histogram sections** display the distribution of classes within a group. It allows analysts to scrutinize class composition (eg. spot unexpected or missing classes) and perform logical set operations (union, intersection, difference) to restrict the contents of the groups.
