Generating a twoway barplot or histogram

[Dusan Petrovic]

Hello everyone,

I have a discrete variable (coffee) [1:5] and I would like to generate a bar plot where for each value of coffee, I have two bars side by side (different colors), one bar for men, one for women.

I've been trying to find a solution, but couldn't.

Thanks a lot for your help

One way to do this is with catplot from SSC.

sysuse auto, clear
ssc inst catplot 
catplot foreign rep78
catplot foreign rep78, recast(bar) asyvars

Hello,
Unfortunately I cannot install new packages on my computer (no admin rights to write in c:\ado\plus\c). Would you have a solution with basic Stata13?

sysuse auto, clear
gen frequency = 1 
graph bar (sum) frequency, over(foreign) over(rep78) asyvars ytitle(frequency)

Great, it's exactly what I wanted. Thanks

Cheers
