How to control the length of the whisker in a box plot produced by SGPLOT?

In GPLOT, we can specify a percentile to control the length of the whiskers in box plots within the range 00 through 25 by using <00…25> in "Interpol=BOX<option(s)><00...25>".  How can we do the same in SGPLOT? By default it seems the whiskers in a box plot by SGPLOT extends to 1.5* IQR (Intra-quartile range). Is there an easy way (option) to adjust the length of a whisker in SGPLOT?

Thanks,

Charlie

Such an option has been added for SAS 9.4.  With SAS 9.3, you can get a box plot with custom whisker lengths by computing your own statistics and using SGPLOT to plot them.  This blog article describes such a case.

Thanks Sanjay for the quick response! good to know that such option as been added for SAS 9.4

The mean markers cannot be produced directly using the "Interpol=BOX<option(s)><00...25>" in GPLOT, is it true? we may have to overlay a scatter plot with mean markers with a box plot in GPLOT?
