twoway and tsline

[ashkan faramarzi]

hi,

I am using below code to plot two different variables with different scales on a same plot but I want to change lines' colors. I used some different options but they didn't work. any idea?

main code: twoway (tsline rev ,yaxis(1)) (tsline price ,yaxis(2)) if code_marque==3

below didnt work:

. twoway (tsline rev ,yaxis(1)) (tsline price,yaxis(2)) if code_marque==3, lc(green blue)
option lc() not allowed

. twoway (tsline rev ,yaxis(1)) (tsline price,yaxis(2), lc(green)) if code_marque==3
variable green not found

. twoway (tsline rev ,yaxis(1)) (tsline price ,yaxis(2), mcolor(green)) if code_marque==3
variable green not found

A certain abandon in the use of commas appears to be the problem. e.g.

webuse grunfeld, clear

twoway (tsline invest if company ==1 ,yaxis(1) lc(blue)) (tsline kstock if company == 1,yaxis(2) lc(green))
