panel.barchart {lattice} | R Documentation |
Default panel function for barchart
.
panel.barchart(x, y, box.ratio = 1, horizontal = TRUE, origin = NULL, reference = TRUE, stack = FALSE, groups = NULL, col = if (is.null(groups)) bar.fill$col else superpose.fill$col, border = if (is.null(groups)) bar.fill$border else superpose.fill$border, lty = if (is.null(groups)) bar.fill$lty else superpose.fill$lty, lwd = if (is.null(groups)) bar.fill$lwd else superpose.fill$lwd, ...)
x |
Extent of Bars. By default, bars start at left of panel,
unless origin is specified, in which case they start there
|
y |
Horizontal location of bars, possibly factor |
box.ratio |
ratio of bar width to inter-bar space |
horizontal |
logical. If FALSE, the plot is ‘transposed’ in the sense that
the behaviours of x and y are switched. x is now the
‘factor’. Interpretation of other arguments change
accordingly. See documentation of bwplot for a fuller
explanation.
|
origin |
origin of the bars. For grouped displays with
stack = TRUE , this argument is ignored and the origin set to
0. Otherwise, defaults to NULL , in which case bars start at
leftmost end of panel.
|
reference |
logical, whether a reference line is to be drawn at the origin |
stack |
logical, relevant when groups is non-null. If
FALSE (the default), bars for different values of the
grouping variable are drawn side by side, otherwise they are
stacked.
|
groups |
optional grouping variable |
col, border, lty, lwd |
|
... |
extra arguments will be accepted but ignored |
A barchart is drawn in the panel. Note that most arguments controlling
the display can be supplied to the high-level barchart
call
directly.
