Please ignore my question. I understand the problem. The x- and y- coordinates in my dataset have a different name than what they are called in the uscoord.dta dataset I mentioned. I think I can figure it out from here. -sc

have a variable called "sr" which is the ratio of women to men at the
United States state level. I would like to have added to the map the
abbreviation for each of the United States states. I appear to be
having trouble with the xplot and yplot syntax within addplot. For

tmap choropleth sr if id!=13 & id!=56, id(id) map(uscoord.dta) palette
(Blues) title(`"`"Sex Ratios for 18-24 year-olds, 2000"'"') subtitle
("White Americans")

I would like to now add the state abbreviation to the map, making it
easier to interpret. I'm reading a user guide written by Maurizio
Pisati, and he writes that addplot requires the x- and y-coordinates
of the variable name. Contained in uscoord.dta are 3 variables:
_ID, _X and _Y. So I type the following:

tmap choropleth sr if id!=13 & id!=56, id(id) map(uscoord.dta) palette
(Blues) title(`"`"Sex Ratios for 18-24 year-olds, 2000"'"') subtitle
("White Americans") addplot(label sr if id!=13 & id!=56, x(X) y(Y))

But this elicits an error, saying that the syntax for addplot is
incorrect. I am assuming that the problem lies with the use of the
x- and y-coordinates. And reading through Dr. Pisati's user guide
more closely, I notice in an example that his x- and y-coordinates
appear to be in the main using file - not in his coordinates file.

Here's the variables I have for me main file:

STATE
NAME
FIPS
LON
LAT
id
fip
sr

Any help is appreciated.
