When you pass a timeseries to plot(), you must pass only the time series, or else the time series and a line specification. For example,
plot(f1)
plot(f1, 'r-')
It is not permitted to pass in two different time series in a single call. If you want to plot two different time series then plot() one, then hold on then plot() the other one.
timeseries objects contain both time and data associated with that time. When you plot() a timeseries object, then the time is used as the x axis and the data is used as the y axes.
