Bar graph, stacking categories

[Rama AbuSharar]

Hi all,
I'm producing a bar graph with one categorical variable containing 4 categories. In my graph I would like 3 of the categories to be stacked and one aside.

This is my code so far:

label define catvar 1 "cat1" 2 "cat2" 3 "cat3" 4 "cat4"
label values catvar catvar

graph bar, over(catvar) asyvars bar(1, fcolor(emerald)) bar(2, fcolor(gold)) bar(3, fcolor(cranberry)) bar(4, fcolor(ebblue))

and this is the output

Any way I could only stack categories 1 2 and 3?

Thank in advance

You'll need some more informative labels. Why be cryptic?

clear 
input catvar 
1
2
2
3
3
3
4
4
4
4
end 

label define catvar 1 "cat1" 2 "cat2" 3 "cat3" 4 "cat4"
label values catvar catvar

gen is4 = catvar == 4 
label def is4 0 "this lot is stacked" 1 "this one is not"
label val is4 is4 

graph bar, over(catvar) over(is4)  asyvars stack bar(1, fcolor(emerald)) bar(2, fcolor(gold)) bar(3, fcolor(cranberry)) bar(4, fcolor(ebblue))
