This example shows average quarterly sales for each department at two of the three manufacturing sites in the TOTALS data set; it excludes the Paris site from the chart.

The program groups the chart data (sites) by department, and subgroups department sales data by quarter. Each site is a midpoint. Because the sites are grouped by department, each midpoint has a separate square for each department and the height of the block represents total sales for that department.

The blocks are subgrouped to show how quarterly sales contribute to total sales; each segment represents sales for a quarter. A legend explaining the subgroup patterns appears below the midpoint grid.

The subgroups use four default patterns, The first three patterns are created by rotating the first default fill, solid, through the three colors in the colors list defined in the GOPTIONS statement. The fourth default pattern is created by using the second default pattern fill, X1, with the first color in the colors list, blue.

Because the first color in the colors list is also the default color for several other elements, the program includes several options that override the default: CTEXT= colors all text, CAXIS= colors the midpoint grid, COUTLINE= colors the pattern outline. For more information on patterns and colors, see Controlling Block Chart Patterns and Colors.
