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: You can overlay histograms with transparent color so that you can see the individual histograms. To do this, assign the variable of interest as X or Y. Assign your overlay variable to the Overlay zone. Then, click the Histogram element icon. See Example of Overlaying Histograms with Transparency in Graph Builder Examples.
For an example illustrating the histogram element, see Example of Features in Graph Builder and Example of Wafer Maps Based on a Cluster Analysis in Graph Builder Examples.

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.
