Two way line

[Tobias Boo]

I am trying to create a line graphic through stata by using twoway line. Sadly only a part of my formula is working right now
twoway line Abnormalreturn Year if DummyHedgefundownership==0, color(red)||
line Abnormalreturn Year if DummyHedgefundownership==1, color(blue) ||
line Stockreturn Year if DummyHedgefundownership==0, color(green) ||
line Stockreturn Year if DummyHedgefundownership==1, color(yellow),

After this , I am trying to create a legenda but it says my parentheses do not balance:
legend(label(1 "Low hedgefund ownership (Abnormal)") label(2 "High hedgefund ownership (Abnormal)") /// label(3 "Low hedgefund ownership (Stock)") label(4 "High hedgefund ownership (Stock)")) /// ytitle("Return") xtitle("Year") title("Abnormal en Stock Return from 2012-2022 per Hedgefund ownership")

It either says the command isn't regonized or that the parentheses do not balance.

Too many commas in your code. Also,

///

wouldn't be recognized interactively, which might be a problem. Try typing this in a do-file editor window

twoway line Abnormalreturn Year if DummyHedgefundownership==0, color(red) ||  ///
line Abnormalreturn Year if DummyHedgefundownership==1, color(blue) || ///
line Stockreturn Year if DummyHedgefundownership==0, color(green) || ///
line Stockreturn Year if DummyHedgefundownership==1, color(yellow) ///
legend(label(1 "Low hedgefund ownership (Abnormal)") label(2 "High hedgefund ownership (Abnormal)") ///
label(3 "Low hedgefund ownership (Stock)") label(4 "High hedgefund ownership (Stock)")) ///
ytitle("Return") xtitle("Year") title("Abnormal and Stock Return 2012-2022 by Hedgefund ownership")

Notes:

0. Here I am assuming that /// occurs at the end of physical lines.

1. Red and green together are not a good idea because of so-called colour blindness.

2. Date ranges like from 2012-2022 are deprecated in authoritative style guides for the English language. Either pair from and to -- or (better) omit from altogether.

Thanks for your feedback, it worked for some reason an error first occured.
