[GCHDSCRT-Charting a discrete numeric variable in a star chart]

This example produces two star charts that show the total number of parts that were rejected each month for a year. The STAR statement uses the DISCRETE option so that each unique value of the numeric variable DATE is a separate midpoint and has a separate spine. Each slice displays the formatted midpoint value and the chart statistic. Specifying FILL=S rotates the solid pattern through all the colors in the style's list of colors as many times as necessary to provide patterns for all the slices.

The second chart uses the NOCONNECT option so that the chart uses spines instead of slices.
