Bar gap option in marginsplot

[Christina Gibson-Davis]

Hello,
I am trying to plot, using marginsplot, the predicted values of wealth by family structure, where the predicted values are represented in a bar graph. I would like there to be a gap between the childless adult bars and adults with children bars, such that the childless adult bars are plotted first, with a gap, followed by the adult with children bars. I have a mutually exclusive variable that defines family structure, called "famcat", that takes on values 1-10. The commands are as follows, where wealth is a function of family structure and years:

reg wealth i.famcat i.year [aw=weight]
margins famcat
marginsplot, xdimension(famcat) << other graph options here >>

Thank you,
Christina

How about using the bar width option as in the following program:

sysuse auto, clear
regress mpg weight i.rep78
margins rep78
marginsplot, recast(bar) noci plotopts(barw(.8)) ylabel(10(2)24
