i have used the guied for the first time to do a box plot and i cant find the opton to add the "+" for the mean , can anyone please help me with this ?
i see from the code that its not using proc boxplot and that its using gplot , maybe its not possible to add the "+" via gplot ?
is it normal that its using gplot ?

With gplot, you can do a boxplot plot, and then do a scatter plot (with the '+' character, or any character you want), and then 'overlay' them. Here is the basic syntax (you can add more options to "fancy it up" a bit!)...
symbol1 interpol=boxcti color=black;
symbol2 interpol=none value=+ color=blue;
proc gplot data=sashelp.class;
plot height*age=1 height*age=2 / overlay haxis=axis1;
