plot.forecast: Forecast plot

In a1967fa/f-cast: Forecasting Functions for Time Series and Linear Models

Description

Plots historical data with forecasts and prediction intervals.

Usage

## S3 method for class 'forecast'
plot(x, include, PI = TRUE, showgap = TRUE,
  shaded = TRUE, shadebars = (length(x$mean) < 5), shadecols = NULL,
  col = 1, fcol = 4, pi.col = 1, pi.lty = 2, ylim = NULL,
  main = NULL, xlab = "", ylab = "", type = "l", flty = 1, flwd = 2,
  ...)

## S3 method for class 'forecast'
autoplot(object, include, PI = TRUE,
  shadecols = c("#596DD5", "#D5DBFF"), fcol = "#0000AA", flwd = 0.5, ...)

## S3 method for class 'splineforecast'
autoplot(object, PI = TRUE, ...)

## S3 method for class 'forecast'
autolayer(object, series = NULL, PI = TRUE,
  showgap = TRUE, ...)

## S3 method for class 'splineforecast'
plot(x, fitcol = 2, type = "o", pch = 19, ...)

Arguments

x	Forecast object produced by forecast.
include	number of values from time series to include in plot. Default is all values.
PI	Logical flag indicating whether to plot prediction intervals.
showgap	If showgap=FALSE, the gap between the historical observations and the forecasts is removed.
shaded	Logical flag indicating whether prediction intervals should be shaded (TRUE) or lines (FALSE)
shadebars	Logical flag indicating if prediction intervals should be plotted as shaded bars (if TRUE) or a shaded polygon (if FALSE). Ignored if shaded=FALSE. Bars are plotted by default if there are fewer than five forecast horizons.
shadecols	Colors for shaded prediction intervals. To get default colors used prior to v3.26, set shadecols="oldstyle".
col	Colour for the data line.
fcol	Colour for the forecast line.
pi.col	If shaded=FALSE and PI=TRUE, the prediction intervals are plotted in this colour.
pi.lty	If shaded=FALSE and PI=TRUE, the prediction intervals are plotted using this line type.
ylim	Limits on y-axis.
main	Main title.
xlab	X-axis label.
ylab	Y-axis label.
type	1-character string giving the type of plot desired. As for plot.default.
flty	Line type for the forecast line.
flwd	Line width for the forecast line.
...	Other plotting parameters to affect the plot.
object	Forecast object produced by forecast. Used for ggplot graphics (S3 method consistency).
series	Matches an unidentified forecast layer with a coloured object on the plot.
fitcol	Line colour for fitted values.
pch	Plotting character (if type=="p" or type=="o").

Details
