How to Proc Boxplot with Descending means?

Does anyone know how to creat a boxplot with descending y axis mean values? It seems the only options for descending is descending alphabetical by the xaxis classfication variable.

I am doing Proc Boxplot with the following code:

Proc Boxplot data=sw_glove;

Plot (concentration)*Process;

By Descending Process;

Run;

I want descending Concentration values, grouped by Process (numeric), not descending process names (alpahbetic).

Another option would be to list out the x axis variable names in the descending value order, but this seems like a lot of meaningless work.

Thanks,

Hi,

In SGPLOT, I would probably do this by sorting the data, then using discreteorder=data on the axis statemetn, as below.

proc sql;
  create table shoes as 
  select region, sales, mean(sales) as mean
  from sashelp.shoes
  group by region
  order by  mean descending,region
  ;
quit;

title1 "discreteorder=data";
proc sgplot data=shoes;
  vbox sales/category=region;
  xaxis type=discrete discreteorder=data;
run;
title1;

Not sure the easiest way to do it with PROC BOXPLOT. If you do need a list of x-values for an x-statement, you could generate it with something like:

170  proc sql;
171    select distinct quote(trim(region)) , mean(sales) as mean
172      into :RegionList separated by " ", :dummy
173      from sashelp.shoes
174      group by region
175      order by mean descending
176    ;
177  quit;

178
179  %put &RegionList;
"Middle East" "United States" "Canada" "Central America/Caribbean" "Western Europe" "Eastern
Europe" "Pacific" "South America" "Africa" "Asia"
