Scott,
Thank you for the suggestion but this does not quite help me. I am
creating time series graphs for several dozen countries with a
-foreach- loop and need a catchall command that does not require me
to know in advance which legend keys should appear in which graph.
Here is an abbreviated excerpt from my command (I use ; as a
delimiter). The variable "country" contains the country name, "year"
is the year, and "var_a" and "var_b" are time series variables. The
macro "countries" contains the names of the countries for which I
need graphs.
foreach x of local countries {;
scatter var_a year if country=="`x'", connect(l) ||
scatter var_b year if country=="`x'", connect(l);
graph export "`x'.wmf";
};
If var_a or var_b have no values, no lines will be plotted. However,
there is still a legend with entries for var_a and var_b. I want to
suppress the respective legend key if a time series does not appear
in the graph. How can this be done? Is there a kind of "legend if
var_a<." command? At least one of my time series always has data, so
there are no completely empty graphs.
