Ah, but I study American politics. Or, as my comparativist colleagues sometimes put it, I'm an area studies scholar focusing on the American case.

That's good news for those working on this.

But this command name is likely to be pronounceable and attractive in
several languages. It is just that I have no idea what they are. As a
Welshman, I must protest at the implicit anglocentrism here that what
looks ugly in English is ugly ipso facto. And the author is a
political scientist too, and should be sensitive to such matters!

I encountered this issue -- that -grc1leg- does not work fully with graphs

-grc1leg- to create -grc1legwby- (GRaph Combine 1 LEGend With BY), that will
work for these plots.  It also works with plots that do not use -by-, so it
can replace -grc1leg-.

I've submitted it for posting to SSC.  In the mean time you can get it from

Perhaps this command also wins some sort of award for its terrible name...

I have the same problem as Ricardo.
I tried using the -grc1leg- command, but I can not figure out how to use
I always end up with all the legends for every graph and an additional one
from using -grc1leg-.
Thus my questions is: How do I create one single legend?

The code I use is something like this:

************** Beginn example ****************
sysuse xtline1, clear

* Creating two more variable to mimic my data setup
gen cal_yesterday = L.calories
bysort person: gen first_half_year = (_n<    175)

* Draw three scater plots
scatter cal_yesterday calories day if person == 1, ///
         by(first_half_year, title("Tess")) ///
scatter cal_yesterday calories day if person == 2, ///
         by(first_half_year, title("Sam")) ///
scatter cal_yesterday calories day if person == 3, ///
         by(first_half_year, title("Arnold")) ///

* combine the three scatter plots
grc1leg g1 g2 g3
*************** End example *****************

Kind regards

You might try the user-written command -grc1leg- (since 1's often look
like l's, that's "grc" + the numeral 1 + "leg").

Subject: st: graph combine&     single legend

I want to combine 4 graphs, each a plot of three lines, using -graph
combine-. Because the legend for the graphs are all the same, I would like
to have a single legend at the bottom. When I use -legend(off)- for three of
the graphs, and leave the legend for the 4th graph, this 4th graph is
smaller than the rest when I combine them. Any solutions will be
