Dashed Border on Spmap Stata

[Joshua Smith]

Hi All,

I have to create a map in which I would like to have solid state borders and dash counties borders. I tried the following:

spmap using counties_coordinates.dta, id(id) mopattern(dash) polygon(data(states_coordinates.dta) osize(0.2) ocolor(black))

but it doesn't work....

Thank you!

Dear Joshua,
as specified in the spmap help file, option mopattern() relates to "Cartogram" maps only, not to choropleth maps. Actually, I don't remember why I did not include a similar option also for choropleth maps -- or for additional polygons as specified by option polygon(), for that matter. Should I get back to spmap for upgrading it, I'll take care of that. Meanwhile, as a partial workaround, you might try the following:

spmap using "states_coordinates.dta", id(id) line(data("counties_coordinates.dta") size(0.2) color(black) pattern(shortdash))

Best wishes,
Maurizio

This feature comes standard in ADePT maps. See screenshot.

Thank you, Maurizio. It really helps. I have one final question: if I have a variable at county level and would like to use different colors for different counties, according to this variable, how can I do that? I mean, I started from the counties coordinates to be able to do that. Thanks again!

Sorry if the previous message wasn't clear. I need to fill in the polygon with different colors (according to a county level variable) and have their borders dashed. Thank you again!

Dear Joshua,
you might try something like this:

use "counties_data.dta", clear
spmap YOURVAR using "counties_coordinates.dta", id(id) ocolor(none ..) ///
   polygon(data("states_coordinates.dta") osize(0.3) ocolor(black))    ///
   line(data("counties_coordinates.dta") size(0.2) color(black) pattern(shortdash))

where counties_data.dta is the Stata dataset containing the county id variable and the county-level variable YOURVAR.


Best wishes,
Maurizio
