Re: st: linkplot does not accept the option -plot(plot)-

[n j cox <n.j.cox@durham.ac.uk>]

The assertion in the title is incorrect. The -plot()-
option in -linkplot- (from SSC) i.e.

linkplot ..., ... plot(<plot>)

is for taking one or more subcommands of -graph twoway- such as 
-scatter-, -line-, -histogram-, etc. -linkplot- itself is not such
a subcommand, so Jos�'s syntax is illegal, as a matter of Stata's 
-twoway graph-, not -linkplot-. This is all documented under 
-plot_option- in Stata 8. It works in Stata 9, but is not documented, 
because -addplot()- does the same thing under a better name.

His question shows a limitation of -linkplot- in that you cannot
distinguish subsets. Scott Merryman's reply showed that you
can borrow the code and do this easily, so that is a good
argument for leaving it be.

Dear People (or, more directly, Dear Nick  Cox):
    I am trying to use the code -linkplot porcento ano if
numerodepesquisas==2, link( idmunicipio) cline(black) plot(linkplot 
porcento
ano if numerodepesquisas==3,link(idmunicipio)cline(red))- in order to have
different colors to identify better the two groups of lines, for
numerodepesquisas==2 and for numerodepesquisas==3.
    However I get the error message -linkplot is not a plot type-
Is it a way to obtain the overlaid graphs?
