You didn't provide a reproducible example, so anyone who answers is just 
guessing, but it seems likely that your
source data is not a time series.

You probably have a data.frame or matrix or similar, and when you use 
plot, you're getting a forced index.

check the class of your input data to make sure that it is xts.

then plot (from zoo, xts, or xtsExtra) or chart_Series or chartSeries 
(from quantmod) will work just fine.
