Bar graph of two string variables with same range of values

[Greg Saldutte]

Hello,

I am attempting to make a bar graph of two string variables that can take on the same value. The two variables are answers to survey questions. I can't post the data, but we can pretend the people were asked their two favorite foods. The data would look like this:

ID fav1 fav2
1 pizza burger
2 burger pizza
3 steak burger
4 burger steak

I would simply like to count the frequencies of all of the answers to fav1 and fav2. I've looked into the stack command, but I don't want to distinguish between fav1 and fav2 in the bar graph, which I don't think is possible using stack.

clear 
input ID str6(fav1 fav2) 
1 pizza burger
2 burger pizza
3 steak burger
4 burger steak
end 

stack fav1 fav2, into(fav) 
graph bar (count), over(fav)

That solved my problem. Thank you.
