PROC SGPANEL and customized boxplots

[n6]

I'm using PROC SGPANEL.  In the first panel I have side by side boxplots for Males and Females for Group A.  In the next panel same thing but for Group B.  Etc.  Five groups total.

But the person I'm doing this for doesn't want the whiskers extending from the boxplot to go to the highest observation that is below the upper fence, like the default is now, and understandably so because it's hard to explain when submitting it to a journal and nobody reading medical journals even knows what the upper fence is.  Instead this person wants the whiskers coming out of the boxplot to go to the 10th and 90th percentile.  Or maybe 5th and 95th.  Or maybe 20th and 80th.  They want to try a few things and see what looks good.  Since there are a couple extreme observations, having the whiskers go to the min and max is not good because it makes the box part get all scrunched and small.

In looking into SAS Help I see the HIGHLOW statement so that may be part of the solution.  But am I going to be able to do that for 10 groups (five for each of Male and Female) and still have side by side boxplots for Male and Female in five panels?  It seems too customized.  It would be really nice if I could just use the code I'm using now except adding a line that tells SAS what percentile to take the whiskers to, but I don't think that's possible.  I'd be happy to be proven wrong on that.

Any info is greatly appreciated.

Percentile option is available in both SGPLOT and SGPANEL with SAS 9.40M2.

With earlier release, you could use the HIGHLOW plot to simulate the result.  See:

Do you know what the option is called?  Because in my SAS Help it says the Percentile option tells SAS how to determine how the percentiles are computed, rather than telling how far to extend the whiskers.

When I select "About SAS" from the Help menut I get "SAS 9.4 TS Level 1M1" so maybe (but hopefully not) that means my version of SAS won't do it.

The option WHISKERPCT is supported with SAS 9.40M2.  You seem to have SAS 9.40M1.  

You could use the method described in the blog article.
