coefplot: Plot-specific axis labels

[William Dowd]

Hello,

I am trying to figure out how to add plot-specific x-axis labels. Specifically, I want to add "OR" to each off the 3 plots' x-axis in the attached graph. It doesn't seem to be possible in the documentation (it's only possible as a global option) but one of Ben Jann's example charts (upper right of page 46 here) seems to have it. Does anyone know how to accomplish this?

Thanks,
Bill

Is this what you have in mind?

sysuse auto
regress mpg headroom trunk length turn if foreign==0
estimates store domestic
regress price mpg headroom trunk length turn if foreign==1
estimates store foreign
coefplot (domestic, xline(100) xlabel(100 "XXX", add) drop(_cons)) || (foreign, xline(1) xlabel(100 "YYY", add) drop(_cons_))

Thanks Dimitriy! I had something a bit more like an xtitle in mind (something that sits below, rather than adjacent to, the axis labels), but this is close.

In that case, you can use the hack of

1. adding a single multi-tiered x-axis label where the top tiers are empty and the bottom tier contains the axis title
2. defining a second label that is numeric to fill the gap.

In principle, this could could be be automated using the internal temporary variables, but I am lazy.

The fiddly way is:

webuse lbw, clear
replace age = age/10
replace lwt = lwt/100

estimates clear
logit low age lwt i.smoke if race=="black":race, nolog
estimates store black
logit low age lwt i.smoke if race=="white":race, nolog
estimates store white
logit low age lwt i.smoke if race=="other":race, nolog
estimates store other

coefplot (black, eform) || (white, eform) || (other, eform), ///
xline(1) xlabel(10 `" " " " "OR"' 10 "10", add labsize(small)) drop(_cons)  byopts(row(1))

This produces:

I am a bit confused why -xlabel(10 `"10" " " "OR"', add labsize(small))- does not work.

Dimitriy,

Thanks so much, this is exactly what I needed.
