Dear statalist members,

I would like to produce a bar graph with the (mean) differences for two different variables between two treatment groups. Producing this graph is not a problem; however, I would like to indicate the statistical significance of the (mean) differences between the treatments for each variable by using brackets and some text_options (?) (i.e., n.s. or the corresponding asterisks and/or the p-values). I attached two exemplary bar graphs, which I found online from other forums.

How can I modify the following code to insert such brackets?

graph bar variable_a variable_b, over(treatment) ///

legend(label(1 "aa") label(2 "bb")) ///

I would greatly appreciate any help on this.

Many thanks and best,

Tugba
