-line price price- is easy but depending on the resolution of the
display the line will not appear entirely straight. The appearance
also depends on how the data are sorted. -function- with the option
n(2) yields a cleaner graph. The setting of the range can be
automated.
. sysuse auto, clear
. sum price, meanonly
. local xmin = r(min)
. local xmax = r(max)
. twoway (scatter weight price) (function y=x, range(`xmin' `xmax')
n(2)), aspect(1)
