panel.xyarea: Plot series as filled polygons.

In latticeExtra: Extra Graphical Utilities Based on Lattice

Plot series as filled polygons.

Description

Plot series as filled polygons connected at given origin level (on y axis).

Usage

panel.xyarea(x, ...)

## Default S3 method:
panel.xyarea(x, y, groups = NULL, origin = NULL, horizontal = FALSE,
             col, col.line, border, lty, lwd, alpha, ...,
             fill, panel.groups = panel.xyarea)

## S3 method for class 'ts'
panel.xyarea(x, y = x, ...)
## S3 method for class 'zoo'
panel.xyarea(x, y = x, ...)

panel.qqmath.xyarea(x, y = NULL, f.value = NULL, distribution = qnorm,
                    qtype = 7, groups = NULL, ..., tails.n = 0)

Arguments

x, y	data vectors.
groups	a factor defining groups.
origin	level on y axis to connect the start and end of the series. If NULL, the polygon is filled to the bottom of the panel. It is flipped if horizontal = TRUE.
horizontal	if this is set to TRUE, then the origin is a level on the x axis, rather than the default which is on the y axis. This is the opposite of what you might expect, but is for consistency with panel.xyplot.
col, col.line, border, lty, lwd, alpha	graphical parameters taken from trellis.par.get("plot.polygon") or trellis.par.get("superpose.polygon") (when groups defined). col.line overrides col.
...	further arguments passed on to panel.polygon. For panel.qqmath.xyarea, passed to panel.xyarea.
fill	ignored; use col instead.
panel.groups	used in panel.superpose.
f.value, distribution, qtype, tails.n	as in panel.qqmath.

Examples

xyplot(sunspot.year, panel = panel.xyarea, origin = 0,
  aspect = "xy", cut = list(n = 3, overlap = 0))

## two series superposed: one filled, one as a line.
xyplot(ts.union(data = sunspot.year, lag10 = lag(sunspot.year, 10)),
  aspect = "xy", cut = list(n = 3, overlap = 0),
  superpose = TRUE,
  panel = panel.superpose,
  panel.groups = function(..., group.number) {
    if (group.number == 1)
      panel.xyarea(...) else panel.xyplot(...)
  }, border = NA, 
  par.settings = simpleTheme(col = c("grey", "black"), lwd = c(5,2)))

## missing values are handled by splitting the series
tmp <- window(sunspot.year, start = 1900)
tmp[c(1:2, 50:60)] <- NA
xyplot(tmp, panel = panel.xyarea, origin = 0)

set.seed(0)
qqmath(~ data, make.groups(baseline = rnorm(100),
                           other = rnorm(100) * 2 - 0.5),
  groups = which, distribution = qunif,
  panel = panel.qqmath.xyarea, xlim = 0:1,
  auto.key = list(points = FALSE, rectangles = TRUE),
  par.settings = simpleTheme(col = c("blue", "green"),
                             alpha = 0.5))
