Hi I use coefplot to stack several graphs together. When I want to add a note, it adds to each sub graph rather than to the bottom of the stacked graph. How can I achieve adding one OVERALL note/text/caption to the overall graph than to each subgraph?

coefplot (normal1, offset(0) keep(treat)) ///
|| (normal2, offset(0) keep(treat))///
||, vertical byopts(compact cols(1) yrescale legend(off)) //
coeflabels(, tlcolor(none) labsize(small)) ///
mlabel(cond(@pval<.01, "***", cond(@pval<.05, "**", cond(@pval<.1, "*", "")))) note("able")

Thanks!
