Hi,

I have a dataframe containing a date object in the first column and numeric
data in two other columns, for a total of three columns. I would like to
plot the 2 numeric data columns against the dates in one window. How do I do
this? It is easy to do if only one data series is to be plotted against a
set of dates, but two or more datasets seems to be harder.

Note: I have daily data where weekends and holidays are left out, e.g. stock
returns. Therefore, I prefer not to construct a new 'dates' vector.

Thanks,

S.A.
