Re: st: spmap with two legends?

[Scott Merryman <scott.merryman@gmail.com>]

The base map and the spatial objects (in this case -point()-)
superimposed onto the base map can have there own legend title using
the option -legtitle()-.  You could also add an over all legend title
with -legend(title("title"))-   Using the graph editor you can achieve
more control over the legend elements but I do not think you have two
separate legends.  In the example below, the -gr_edit- lines are taken
from a recording of the graph editor to alter the legend titles and
the legend position.



 use "Italy-RegionsData.dta", clear
 spmap relig1 using "Italy-RegionsCoordinates.dta", id(id)           ///
       clmethod(stdev) clnumber(5)
        ///
       legenda(on) legtitle(Title for Base)
         ///
       title("Pct. Catholics without reservations", size(*0.8))         ///
       point(data("Italy-Capitals.dta") xcoord(xcoord) ycoord(ycoord) ///
       by(size) fcolor(orange red maroon) shape(s ..)       ///
       legenda(on)  legtitle(" " "Title for Point") )              ///
       subtitle("Italy, 1994-98" " ", size(*0.8)) area(pop98)           ///
       map("Italy-OutlineCoordinates.dta") mfcolor(stone)
name(gr1,replace)

gr_edit .legend.plotregion1.label[1].style.editstyle size(vsmall) editcopy
gr_edit .legend.plotregion1.label[1].xoffset = -4
gr_edit .legend.plotregion1.label[7].style.editstyle size(vsmall) editcopy
gr_edit .legend.plotregion1.label[7].xoffset = -4
gr_edit .legend.xoffset = -6
