For overlay charts with multiple stars, the lines for the stars are rotated through different line styles and colors so that the different stars can be easily seen. Rather than relying on the default rotation patterns, you can control the line colors, widths, and styles with the CSTARS=, LSTARS=, and WSTARS= options.
This example features the following options:
CSTARS= specifies a different color for each of the star outlines in the chart.
WSTARS= specifies the width of the line for each star outline.
LSTARS= specifies a solid line as the line style for each star outline.
STARCIRCLES= determines that two reference circles are superimposed on the star charts. The value 1.0 determines that a circle with a radius equal to the spoke length is displayed. The value 0.5 determines that a circle is displayed half way between the outer circle and the smallest circle (value 0.0) that could be drawn for the chart. The value 0.0 would display a circle at the minimum data value, which does not mean that it is actually 0. For example, for data values of 4, 8, 10, and 12, STARCIRCLES=(0.0 1.0) would draw circles at 4 and 12.
