Plots historical data with multivariate forecasts and prediction intervals.

## Arguments

- object
Multivariate forecast object of class

`mforecast`

. Used for ggplot graphics (S3 method consistency).- PI
If

`FALSE`

, confidence intervals will not be plotted, giving only the forecast line.- facets
If TRUE, multiple time series will be faceted. If FALSE, each series will be assigned a colour.

- colour
If TRUE, the time series will be assigned a colour aesthetic

additional arguments to each individual

`plot`

.- series
Matches an unidentified forecast layer with a coloured object on the plot.

- x
Multivariate forecast object of class

`mforecast`

.- main
Main title. Default is the forecast method. For autoplot, specify a vector of titles for each plot.

- xlab

## Examples

```
library(ggplot2)
lungDeaths <- cbind(mdeaths, fdeaths)
fit <- tslm(lungDeaths ~ trend + season)
fcast <- forecast(fit, h=10)
plot(fcast)
autoplot(fcast)
carPower <- as.matrix(mtcars[,c("qsec","hp")])
carmpg <- mtcars[,"mpg"]
fit <- lm(carPower ~ carmpg)
fcast <- forecast(fit, newdata=data.frame(carmpg=30))
plot(fcast, xlab="Year")
autoplot(fcast, xlab=rep("Year",2))
