super segmented barplot

Description

Plot a barplot, with bars nested and ranging from a max to a minimum value. A similar graphic is used on the weather page of the New York Times.

Usage

superbarplot(x, names = 1:dim(x)[2], names_height = NULL,
  col = gray(seq(0.8, 0.5, length = dim(x)[1]/2)), ...
)

Arguments

x	A matrix with each pair of rows representing a min and max for the bar.
names	Place a name in each bar.
names_height	Where the names should go
col	What colors to use for the bars. There should be half as many specified as rows of x
...	passed to plot.window.

Details

A similar graphic on the weather page of the New York Times shows bars for record highs and lows, normal highs and lows and actual (or predicted) highs or lows for 10 days of weather. This graphic succintly and elegantly displays a wealth of information. Intended as an illustration of the polygon function.

Value

Returns a plot, but no other values.

superbarplot(x,names=the.names)
