Plotting bar plots for categorical variables in STATA

I have a survey data baseline and endline. I am trying to plot bar plot for qualification of the respondent in each group (baseline/endline).

I am using the following code:

 graph bar, over(qualification) over(time)

It is giving me different output from what I want. my output I want the bars for endline and baseline for each category to be present parallel.

I am also attaching a reference picture to get the better idea about what I want.output which I want

Solution

  • The order of the over options of graph bar matters.

    Consider this example:

    clear
input x str1 a b
1 "a" 1
2 "a" 2
3 "b" 1
4 "b" 2
end

graph bar x, over(a) over(b) title("over(a) over(b)")
graph bar x, over(b) over(a) title("over(b) over(a)")

    It looks like you need to swap the order of your over options.
