st: re multilevel scatterplots

["Richard Hiscock" <rhiscock@netspace.net.au>]

I have a data set  in the form

                    y variable (distance in mm)      x variable (3
technique)      id(pt)

                            45                                        1

                            35                                        2

                            42                                        3

                            34                                        1

                            43                                        2

                            24                                        3
2

  ......etc

and wish to plot the y variable against 3 techniques with line connecting
each id.
This is easily achieved in MLwin however it would be useful to produce a
higher quality graph in stata
I have tried the usual sources (graph manual,ats & FAQ) with no lick
Any suggestions would be useful

thanks Richard
