Let's say I have two dummy variables like this.

Code:
set obs 100
gen A=runiformint(0,1)
gen B=runiformint(0,1)
I want to graphically see how many are A=1, B=1 & how many are A=1,B=0 & how many are A=0,B=1 & how many are A=0, B=0.

So basically I need a bivariate histogram. Is it available on Stata? I googled a bit and it seems R has it.
