Produce the first horizontal bar chart. Because neither the MIDPOINTS= option nor the DISCRETE option is used, the procedure automatically selects the midpoints. The SUBGROUP= option divides the bars according to the values of SEX and automatically generates a legend. The AUTOREF option adds reference lines to the chart at each major tick mark. The CLIPREF option positions the reference lines behind the bars.
