If you read in these sample data from Scott's example to have variables -group- -ease- then catplot bar group ease, asyvars produces essentially the same graph. -catplot- has been on SSC since 2003 and is discussed in SJ-4-2 gr0004 .

Cox Q2/04 SJ 4(2):190--215 (no commands) discusses graphical possibilities for categorical and compositional data In other words, you are not obliged to do your own reshaping or re-structuring of data.

I would like to create a bar graph with the x axis labelled 1, 2, 3, 4, 5 for each Likert level. I would then simply like to plot frequencies of responses as the bars, so that each level of the Likert scale would have one for each group (i.e. two bars of frequencies for each of 1, 2, 3, 4, 5). > > My attempt (which creates the look of the graph that I want): > > clear * > input ease_level group1 group2 > 1 24 26 > 2 13 15 > 3 12 12 > 4 8 6 > 5 1 6 > end > > graph bar (asis) group1 group2, over(ease) > > This works well, except my data are not in this format.
