Make a confidence interval for a proportion

[nab102]

Hi,

I'm new to sas and want to make confidence for braplots ( bounding at 0-100%) . I have dataset with three variables and they are all categorical. This is how the data looks like. 

                 Area_of_interst , Meds, Response, 
                 "Internal Med", "asprin", "yes",
                 "Internal Med", "vitamins","no",
                  "Internal Med", "folic acid","yes",
                  "Emergency Med", "asprin", "yes",
                 "Emergency Med", "vitamins","no",
                  "Emergency Med", "folic acid","yes",

 This is the SAS code I have . Please help me

proc sgplot data = out2;
vbar meds / response = RowPercent group=area_of_interest groupdisplay=cluster ;
where response = "yes";
run;
