I have a margins plot in Stata with too many lines on it to read the graph well. I want to remove the data that is not the focus of my plot.
For example, the output I have is this marginsplot with five lines, each representing a racial group:

However, I'd only like to display two lines, representing two racial groups (URM and White, Domestic)
Right now my code is:
reg y x##i.race $controls
margins x, by (race)
marginsplot
