GBXWHSKR Call

draws box-and-whiskers plots

RUN GBXWHSKR( matrix);

where matrix is any matrix.

The GBXWHSKR module draws a box-and-whiskers plot for univariate numeric data contained in the specified matrix. The box outlines the quartile range, and the minimum, median, and maximum points are labeled on the plot. You cannot produce graphics until you invoke the CALL GSTART statement. The plot created by the GBXWHSKR module remains open for further additions until you specify the CALL GCLOSE statement, which terminates the current graphics segment. The module source code can be edited for changes, such as adding viewports, text, or colors.
