stacked bar graph with conditions

[Yosef Cohen]

I am able to create a bar graph using -graph bar (sum) patients if ccta==1, over(year) by(region)- but instead of having four separate graphs for regions I would like to create a stacked bar graph. I have tried using -graph bar (sum) patients if ccta==1, over(year) by(region) stack- but obtain the same results.

Thanks for the help

Try:

graph bar (sum) patients if ccta==1, over(region) over(year) asyvars stack
