Zhiqiang Wang and Nick Cox have written -longplot- that does exactly what you want. findit longplot I have been puzzling with a new version of longplot using the new graph features in Stata 10. I call my programme -longgraph-, but it is not really ready yet, but if you would like to try it out, here it is: Copy the codes below and save it into -longgraph.ado- Regards Kim ======================================================================= *! 1.0.0 KLM 18 Nov 2007 program define longgraph, rclass version 10 /* LONGGRAPH is inspired by 'longplot' (ZW & NJC 2001), but compared to longplot, LONGGRAPH is rudimentary and simple (although to the best of my current programming ability). Feel free to improve it! */ * /* like "longplot", LONGGRAPH graph values of a response variable yvar against a time variable xvar by groupvar such that each group is shown by a distinct connected line with different colors and markers, depending on which scheme is used. LONGGRAPH uses the valuelabels of groupvar for legend. LONGGRAPH allows for parsing of twoway_options such as title, Axis and scheme using the graphopt(string) option. Connect_options can be specified using the C(option). Axis_choice_options is NOT implemented! However, the complete twoway command can be retirved from the returmed local macro: r(lg) (use: di "`r(lg)'") for further manual elaboration. */ syntax varlist(min=2 max=2 numeric) [if/] [in] /// , BY(varname) [GRaphopt(string)] [C(string)] qui levelsof `by', local(levels) local N: word count `levels' local if = "& `if'" if "`c'" == "" { local c c(l) } else { local c c("`c'") } local cr foreach l of local levels { if `l'<`N' { local cr `cr' scatter `varlist' if `by'==`l' `if' `in' /// , legend(lab(`l' `: label (`by') `l' ' )) `c' sort || } else { local cr `cr' scatter `varlist' if `by'==`l' `if' `in' /// , legend(lab(`l' `: label (`by') `l' ' )) `c' sort ||, `graphopt' } } twoway `cr' return local lg `cr' end ============================================================ Kim Lyngby Mikkelsen Stilling Seniorforsker Uddannelse Cand.med. Ph.D. Telefon 39165467 Email klm@ami.dk All, Sorry if this question is too simple, but here goes: I have a panel dataset. I want to create simple graphs for each unit (called countrygroup) across time. Initially I tried - by countrygroup: scatter data301 time But Stata tells me by does not work with scatter. I then tried scatter data301 time, by countrygroup This works but Stata puts all the graphs on one page. There are over 100 of them so they are too small to be useful. Is there anyway I can see each graph on its own page? Or save them individually. Is there a command for this. I know I could use the if function but this seems time consuming. P.S (I am using Stata version 8.2) Thanks Daniel Wilde --On 12 December 2007 15:53 -0200 José Maria Pacheco de Souza <jmpsouza@usp.br> wrote: > It is always a pleasure to read any explanation given by Bill Gould. > José Maria > Jose Maria Pacheco de Souza, Professor Titular (aposentado) > Departamento de Epidemiologia/Faculdade de Saude Publica, USP > Av.
