You need to summarize your variables, and save the means in locals, then
you use the option xline() and yline()

*/ -------- start example ----------
clear
set obs 1000
gene a = rnormal()
gene b = runiform()
sum a, meanonly
local a = r(mean)
sum b, meanonly
local b = r(mean)
scatter a b, xline(`b') yline(`a')
*/ -------- end -----------------------

Dear statalist.

I drew a scatter plot and want to add horizontal line with mean( x
values) and vertical line with mean (y values).

Do you have any idea?

Thanks.
