plot.HoltWinters {stats} | R Documentation |
Produces a chart of the original time series along with the fitted values. Optionally, predicted values (and their confidence bounds) can also be plotted.
## S3 method for class 'HoltWinters': plot(x, predicted.values = NA, intervals = TRUE, separator = TRUE, col = 1, col.predicted = 2, col.intervals = 4, col.separator = 1, lty = 1, lty.predicted = 1, lty.intervals = 1, lty.separator = 3, ylab = "Observed / Fitted", main = "Holt-Winters filtering", ylim = NULL, ...)
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, lty |
Color/line type of original data (default: black solid). |
col.predicted, lty.predicted |
Color/line type of fitted and predicted values (default: red solid). |
col.intervals, lty.intervals |
Color/line type of prediction intervals (default: blue solid). |
col.separator, lty.separator |
Color/line type of observed/predicted values separator (default: black dashed). |
ylab |
Label of the y-axis. |
main |
Main title. |
ylim |
Limits of the y-axis. If NULL , the range is chosen
such that the plot contains the original series, the fitted values,
and the predicted values if any. |
