This example uses the FITNESS data set to produce a horizontal bar chart that shows the number of people in each age group in a fitness program.

It charts the numeric variable AGE with the frequency statistic. Because the values of AGE are continuous, the procedure automatically divides the ages into ranges and displays the midpoint of each age range. The frequency statistic calculates the number of observations in each range. The chart statistic defaults to FREQ because the SUMVAR= and TYPE= options are omitted. The table of statistics displays all the statistic values.

The second part of this example modifies the midpoint axis and the table of statistics, and uses RUN-group processing to produce the following chart. This part of the program specifies the midpoint value for each bar and requests only the FREQ statistic for the table.
