If you specify the MIN and MAX keywords in an INSETGROUP statement in PROC BOXPLOT, the minimum and maximum whisker values are displayed when ODS Graphics is enabled. This means if you have specified BOXSTYLE=SCHEMATIC, SCHEMATICID or SCHEMATICIDFAR in the PLOT statement and there are outliers beyond the whiskers for an individual box-and-whisker plot, the displayed minimum and maximum values for that individual plot will be wrong.

If you disable ODS Graphics, the traditional GRSEG graphics output is correct. To disable ODS Graphics, add the following line of code right before PROC BOXPLOT:

ods graphics off;

ODS Graphics can be enabled again by specifying the following line of code after the RUN or QUIT statement at the end of PROC BOXPLOT:

ods graphics;

There is no circumvention for this problem with ODS Graphics enabled.
