panel.axis: Panel Function for Drawing Axis Ticks and Labels

Description

This is the function used by lattice to draw axes. It's typically not used by users, except those wishing to create advanced annotation. Keep in mind issues of clipping when trying to use it as part of the panel function.

Usage

panel.axis(side = c("bottom", "left", "top", "right"),
           at,
           labels = TRUE,
           draw.labels = TRUE,
           check.overlap = FALSE,
           outside = FALSE,
           ticks = TRUE,
           half = !outside,
           which.half,
           tck = 1,
           rot, ...)

synopsis

panel.axis(side = c("bottom", "left", "top", "right"), at = pretty(scale.range), labels = TRUE, draw.labels = TRUE, check.overlap = FALSE, outside = FALSE, ticks = TRUE, half = !outside, which.half = switch(side, bottom = "lower", left = "upper", top = "upper", right = "lower"),

tck = as.numeric(ticks), rot = if (is.logical(labels)) 0 else c(90, 0),

text.col = axis.text$col, text.alpha = axis.text$alpha, text.cex = axis.text$cex, text.font = axis.text$font, text.fontfamily = axis.text$fontfamily, text.fontface = axis.text$fontface,

line.col = axis.line$col, line.lty = axis.line$lty, line.lwd = axis.line$lwd, line.alpha = axis.line$alpha)

Details

panel.axis can draw axis tick marks inside or outside a panel (more precisely, a grid viewport). It honours the (native) axis scales. Used in panel.pairs for splom, as well as for all the usual axis drawing by the print method for ``trellis'' objects. It can also be used to enhance plots `after the fact' by adding axes.
