Bar plot comparing multiple variables among two groups

[Chris Liu]

Hi all,

I am trying to draw a bar plot comparing multiple variables among two groups. var1 is the group indicator (1 or 2). The figure should have four bars. From left to right, the mean of var2 in group 1, the mean of var2 in group 2, the mean of var3 in group 1, and the mean of var3 in group 2. The first bar and second bar are side-by-side, so are the third and fourth bars. There is a gap between the second and the third bar. The first and third bars use one color (red), while the second and fourth bars use another color (blue).

Thank you in advance.

You can do this with statplot from SSC. statplot is a good search term to find several discussions here on Statalist.

clear
input float(var1 var2 var3)
1 1 1
1 0 0
1 1 0
1 1 0
2 0 1
2 0 1
2 0 1
2 1 0
end

* a fairly standard plot, which is not what you want 
graph bar var2 var3, over(var1) bar(1, color(red)) bar(2, color(blue))

ssc inst statplot 

statplot var2 var3, over(var1)  asyvars bar(1, color(red)) bar(2, color(blue)) recast(bar)
