spmap_fix color of a certain index

[sungwook kim]

Dear Statalist,

I would like to fix colour for category using spmap. For example, I want to express a certain index

o<ind<0.5 'light blue'
0.5<ind<1 'dark blue'
-0.5<ind<0 'light red'
-1<ind<-0.5 'dark red'
The purpose of doing this is to compare two maps.

spmap ind_sar using a_coord, id(stid) legend(position(2)) legtitle("Ind") fcolor(Reds2) ocolor(blue) osize(vthin)

Many thanks in advance!

Kind regards,

Sungwook

You can specify a color list in spmap. You do not have to use the color palettes. For example you could alter the intensity of the color or specify them directly (in this case in terms of RGB):

use "Italy-RegionsData.dta", clear
spmap relig1 using "Italy-RegionsCoordinates.dta", id(id) clm(custom) /// 
    clb(20 40 50 60 70) fcolor( red*.5 red*1.25 blue*.5 blue*1.25)
spmap relig1 using "Italy-RegionsCoordinates.dta", id(id) clm(custom) /// 
    clb(20 40 50 60 70) fcolor( "0 0 255" "179 179 255" "255 179 179" "255 0 0")
