#### 15.4.2 Histogram ¶

The subcommand `HISTOGRAM` produces a histogram. Only one variable is allowed for the histogram plot. The keyword `NORMAL` may be specified in parentheses, to indicate that the ideal normal curve should be superimposed over the histogram. For an alternative method to produce histograms see EXAMINE. The following example produces a histogram plot for the variable weight.
