Taken from the trace of -graph query linepatternstyle-, here is one
way to obtain a list of the line patterns:
local x : dir "C:\Program Files\Stata11\ado\base/style" files
"linepattern-*.style"
local x : list clean x
local x: subinstr local x "linepattern-" "", all
local x: subinstr local x ".style" "", all
local x: subinstr local x "blank" "", all
disp "`x'"
and then for each number of the by(variable) you could cycle through
local macro x to pick up a different line pattern.
