Plot function for HoltWinters objects

Description

Produces a chart of the original time series along with the fitted values. Optionally, predicted values (and their confidence bounds) can also be plotted.

Usage

## S3 method for class 'HoltWinters'
plot(x, predicted.values = NA, intervals = TRUE,
                 separator = TRUE, col = 1, col.predicted = 2,
                 col.intervals = 4, lty.separator = 3,
                 ylab = "Observed / Fitted",
                 main = "Holt-Winters filtering", ...)

Arguments

`x`	Object of class `"HoltWinters"`
`predicted.values`	Predicted values as returned by `predict.HoltWinters`
`intervals`	If `TRUE`, the prediction intervals are plotted (default).
`separator`	If `TRUE`, a separating line between fitted and predicted values is plotted (default).
`col`	Color of original data (default: black)
`col.predicted`	Color of fitted/predicted values (default: black).
`col.intervals`	Color of predicition intervals (default: blue).
`lty.separator`	Line type of the separator (default: dashed line).
`ylab`	Label of the y-axis.
`main`	Main title.
`...`	Other graphics parametes.
