If I understand this correctly, the problem need not involve putting
data into Mata only to have to pull them out again.

There are various more direct solutions. Here is one. See also

egen group = group(clas_cnae), label
su group, meanonly

forval i = 1/`r(max)' {
	twoway line Y ano if group == `i', title("`: label (group) `i''")

You will presumably want to save those graphs too.
