1. Read the posting guide!
2. Provide a reproducible example (as suggested in the posting guide).
3. Use a time series object for your time series, see e.g. package "zoo".
If you set up a multivariate time series, you can get what you want by
plot(z, plot.type = "single")
See the "zoo" vignettes for more information.
4. If you really want to modify the code below, you probably need to
repeat (the right elements of) datum2 in lines(), e.g.,
lines(datum2[...], gvarindus, lwd = 2)
and you should really drop unnecessary brackets as in
ylab = ("Return")
hth,
