marginsplot and clustered column (bar) graphs

[Taletha Derrington]

Hi,

I'm a new user and cannot get marginsplot to do a basic clustered column (bar) graph with categories on x axis and 2 groups for each category plotted on the y aix (e.g., treated, control).

I tried this code with STAT v15:

margins, over(treated_lanham grade3)
marginsplot, xdim(grade3) plot(treated_lanham) recast(bar) allx

but it's stacking the 2 groups in one column (that are differently colored) instead of 2 differently colored columns side by side. Any help would be appreciated!

You can get separate graphs with the -by()- option, otherwise I think you need to save the margins and generate your graph using twoway.

marginsplot, xdim(grade3) plot(treated_lanham) recast(bar) allx by(treated_lanham)
