Graph combine different titles for columns

[Clemens Lehner]

I use graph combine to combine multiple graphs in two columns and I would like to have two different centered titles at the beginning of each column. Does anyone have an idea how to achieve that? I tried different title options but they are always centered in the middle.

graph combine gr1.gph gr2.gph gr3.gph gr5.gph gr6.gph gr7.gph, cols(2)

Title 1	Title 2
graph 1	graph 4
graph 2	graph 5
graph 3	graph 6

Combine each column first and then combine the columns:

sysuse auto,clear
forv i = 1/6 {
    scatter mpg price, name(gr`i', replace)
}
graph combine gr1 gr2 gr3, title(Title 1) name(grcol1,replace) row(3)
graph combine gr4 gr5 gr6, title(Title 2) name(grcol2,replace) row(3)
graph combine grcol1 grcol2, col(2)
