The Histogram element shows a variable’s distribution using binning. For more details about histograms, see Histograms in the Basic Analysis book.
If the same variable is specified for both X and Y, then the Y role is ignored and a single histogram appears.

Tip: If you have multiple graphs, you can color or size each graph by different variables. Drag a second variable to the Color or Size zone, and drop it in a corner. In the Variables option, select the specific color or size variable to apply to each graph.
