Creating histograms for discrete variable for Treatments next to each other

[Muhammad Arslan Iqbal]

Hi Everyone,

I have the following data.

T1_Success --> Number of correct answers
Treatment --> Treatment assigned

I want to make histogram of T1_success across treatments. However, I don't want it to be overlapping like the one generated by twoway histogram command.

I want the histogram bars next to each other for each treatment. For instance, for number of correct answers = 5, I want all histogram bars (one for each treatment) to be shown next to each other. Similarly, for number of correct answers =6 , I want all histogram bars (one for each treatment) to be shown next to each other and so on.

Any help or link for such an example will be much appreciated.
