Plots historical data with forecasts and prediction intervals.

## Usage

```
# S3 method for 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 forecast
autoplot(
object,
include,
PI = TRUE,
shadecols = c("#596DD5", "#D5DBFF"),
fcol = "#0000AA",
flwd = 0.5,
...
)
# S3 method for splineforecast
autoplot(object, PI = TRUE, ...)
# S3 method for forecast
autolayer(object, series = NULL, PI = TRUE, showgap = TRUE, ...)
# S3 method for 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"`

).
