##### Plotting Time-Series Objects

Plotting method for objects inheriting from class `"ts"`

.

##### Usage

```
"plot"(x, y = NULL, plot.type = c("multiple", "single"), xy.labels, xy.lines, panel = lines, nc, yax.flip = FALSE, mar.multi = c(0, 5.1, 0, if(yax.flip) 5.1 else 2.1), oma.multi = c(6, 0, 5, 0), axes = TRUE, ...)
"lines"(x, ...)
```

##### Arguments

- x, y
- time series objects, usually inheriting from class
`"ts"`

. - plot.type
- for multivariate time series, should the series by plotted separately (with a common time axis) or on a single plot?
- xy.labels
- logical, indicating if
`text()`

labels should be used for an x-y plot,*or*character, supplying a vector of labels to be used. The default is to label for up to 150 points, and not for more. - xy.lines
- logical, indicating if
`lines`

should be drawn for an x-y plot. Defaults to the value of`xy.labels`

if that is logical, otherwise to`TRUE`

. - panel
- a
`function(x, col, bg, pch, type, ...)`

which gives the action to be carried out in each panel of the display for`plot.type = "multiple"`

. The default is`lines`

. - nc
- the number of columns to use when
`type = "multiple"`

. Defaults to 1 for up to 4 series, otherwise to 2. - yax.flip
- logical indicating if the y-axis (ticks and numbering)
should flip from side 2 (left) to 4 (right) from series to series
when
`type = "multiple"`

. - mar.multi, oma.multi
- the (default)
`par`

settings for`plot.type = "multiple"`

. Modify with care! - axes
- logical indicating if x- and y- axes should be drawn.
- ...
- additional graphical arguments, see
`plot`

,`plot.default`

and`par`

.

##### Details

If `y`

is missing, this function creates a time series
plot, for multivariate series of one of two kinds depending on
`plot.type`

.

If `y`

is present, both `x`

and `y`

must be univariate,
and a scatter plot `y ~ x`

will be drawn, enhanced by
using `text`

if `xy.labels`

is
`TRUE`

or `character`

, and `lines`

if
`xy.lines`

is `TRUE`

.

functionality.

##### Examples

`library(stats)`

```
require(graphics)
## Multivariate
z <- ts(matrix(rt(200 * 8, df = 3), 200, 8),
start = c(1961, 1), frequency = 12)
plot(z, yax.flip = TRUE)
plot(z, axes = FALSE, ann = FALSE, frame.plot = TRUE,
mar.multi = c(0,0,0,0), oma.multi = c(1,1,5,1))
title("plot(ts(..), axes=FALSE, ann=FALSE, frame.plot=TRUE, mar..., oma...)")
z <- window(z[,1:3], end = c(1969,12))
plot(z, type = "b") # multiple
plot(z, plot.type = "single", lty = 1:3, col = 4:2)
## A phase plot:
plot(nhtemp, lag(nhtemp, 1), cex = .8, col = "blue",
main = "Lag plot of New Haven temperatures")
## xy.lines and xy.labels are FALSE for large series:
plot(lag(sunspots, 1), sunspots, pch = ".")
SMI <- EuStockMarkets[, "SMI"]
plot(lag(SMI, 1), SMI, pch = ".")
plot(lag(SMI, 20), SMI, pch = ".", log = "xy",
main = "4 weeks lagged SMI stocks -- log scale", xy.lines = TRUE)
```
