d areastack.
d
d graph command like "twoway area" which "stacks" the over(), instead of overlayin
d ng them.
d This program is similar to "twoway area",
d except that it "stacks" the areas to a cumulative height
d (similar to "graph bar ... , stack").
d 
d At it's core, this program creates a "cumulative" y-variable
d . bys x_var (over_var) : gen cumulative = sum(x_var)
d 
d Then, it executes a command like this:
d . graph twoway
d (area cumulative x_var if over_var==4 )
d (area cumulative x_var if over_var==3 )
d (area cumulative x_var if over_var==2 )
d (area cumulative x_var if over_var==1 )
d , legend(order(4 3 2 1) label(1 "over_var label 1") ... label(4 "over_var label 
d 4"))
d 
d Any options are passed along to the graph twoway command.
