rawXLim: Get or set current plot limits
Description
Part of the playwith Application Programming Interface.Usage
rawXLim(playState, space = "plot")
rawYLim(playState, space = "plot")
rawXLim(playState) <- value
rawYLim(playState) <- value
Arguments
playState
a playState object representing the plot, window and device. Details
rawXLim returns the current plot limits, on a numeric, linear scale.
This is as simple as:
playDo(playState, space=space, list(
x=convertX(unit(0:1, "npc"), "native", valueOnly=TRUE),
y=convertY(unit(0:1, "npc"), "native", valueOnly=TRUE)))
except that the default space="plot" will always return a value: if
it is a Lattice plot with multiple panels, one will be chosen arbitrarily.
The assignment form converts a numeric range, in the raw native plot coordinates, to values suitable for
the plot xlim argument: it may convert back from log-transformed scales, and convert to factor levels if necessary.
It then updates the current plot call with the new value.
