autoplot(
  object,
  series = NULL,
  xlab = "Time",
  ylab = deparse(substitute(object)),
  main = NULL,
  facets = FALSE,
  colour = TRUE,
  ...
)

## S3 method for class 'numeric'
autoplot(
  object,
  series = NULL,
  xlab = "Time",
  ylab = deparse(substitute(object)),
  main = NULL,
  ...
)

## S3 method for class 'ts'
fortify(model, data, ...)
