This may not be too helpful as -margins- is not available after -mi
estimate-, however it is easy to plot continuous by continuous by
categorical interactions using -margins- and -marginsplot-.
For example:
sysuse nlsw88.dta,clear
logit married ibn.race ibn.race#(c.wage c.grade c.wage#c.grade), nocon
margins race, at(grade=(0(6)18) wage = (10(10)40))
marginsplot , bydim(race) plotdimension(grade, allsimple)
legend(subtitle(Education) rows(1)) byopts(rescale) noci
This example is adapted from Michael Mitchell's Interpreting and
Visualizing Regression Models Using Stata, chapter 13 "Continuous by
continuous by categorical interactions"
