Hello, I am trying to plot a graphic with many lines with the
following
command:
plot(datas[1:n,1],datas[1:n,2],type="l",main="SP500 Prices and Moving
Averages",xlab="Date",ylab="Prices",col="black")
lines(datas[1:n,1],datas[1:n,3],type="l",col="green",lty="solid")
But I just see the first curve. I have tried it on the console
separately
and it´s still not working. There is no error message but I can´t
see the
second curve. Is there a parameter that I need to change with par()?
Thank you
