If one or more interval variables are selected in a data table when you select Graph Histogram, then the Histogram dialog box does not appear. Instead histograms are created of the selected interval variables.

You can also select nominal and interval variables and select Graph Histogram. A bar chart appears for each nominal variable; a histogram appears for each interval variable.

If a variable has a Frequency role, it is automatically used as the frequency variable for the plots; the frequency variable does not need to be selected.

If you create a matrix of plots from selected variables, you can close the matrix by pressing the F11 key while any plot is active and selecting from the pop-up menu. Alternatively, you can use the Workspace Explorer to quickly close plots. (See the section Workspace Explorer.)
