# RE: st: Graphing multiple series groups

 From "David Radwin" To Subject RE: st: Graphing multiple series groups Date Thu, 11 Apr 2013 14:02:52 -0700 (PDT)

5000 seems like a lot of lines for one graph, but you could write:

forvalues i = 1/5000 {
local graphs `graphs' (line yvar xvar if group == `i')
}
graph twoway `graphs'

A nice introduction to foreach and forvalues loops is Kit Baum's "A little
bit of Stata programming goes a long way..." at
http://fmwww.bc.edu/ec-p/wp612.pdf . His introductory Stata programming
book is also an excellent way to learn such things.
