Boxplot for different treatments

[hua]

Thank you for help! I tried the two vbox, but the overlay doesn't looks good. Maybe modifying my data before plot is the way to do so.

Hi @hua. 

What is the question here? 🙂

If you are overlaying two boxplots, use the DISCRETEOFFSET option to move one to the left and one to the right so that they do not overlap. Here is a simple example:

proc sgplot data=sashelp.class;
vbox weight / category=age discreteoffset=-0.22;
vbox height / category=age discreteoffset=0.22;
run;

Hope this helps!
