I agree with most of the things Svend said, however, regarding the ||
notation I recently changed my mind. I meanwhile write commands like
the above as follows:
twoway ///
|| line mpg price if fore == 0 , sort lc(blue) lp(dash) ///
|| line mpg price if fore == 1 , sort lc(black) ///
|| , legend(order(1 "white sex ratio" 2 "black sex ratio")
Note that I use || to start the plots instead of ending them as it is
proposed in the manual. I admitt that the first mention of || is not
necessary but I think that it makes the command at least as transparent
as with the () notation. Moreover I think it is even nicer with longer
plot-subcommands:
twoway ///
|| line mpg price ///
if fore == 0 & whatever you like ///
, sort lc(blue) lp(dash) bla bla bla bal bal ///
|| line mpg price ///
if fore == 1 & some other exp ///
, sort lc(black) etc etc etc etc ///
|| , legend(order(1 "white sex ratio" 2 "black sex ratio")

Uli,
I think this is a very good and transparent style. I might change my mind,
too.
