axis.mult

Display an axis with values having a multiplier

Description

An axis is displayed on an existing plot where the tick values are divided by a multiplier and the multiplier is displayed next to the axis.

Usage

axis.mult(side=1,at=NULL,labels,mult=1,mult.label,mult.line,
  mult.labelpos=NULL,...)

Arguments

`side`	which side to display
`at`	where to place the tick marks - defaults to axTicks()
`labels`	tick labels - defaults to at/mult
`mult`	the multiplier factor
`mult.label`	the label to show the multiplier - defaults to "x mult"
`mult.line`	the margin line upon which to show the multiplier
`mult.labelpos`	where to place mult.label - defaults to centered and outside the axis tick labels
`...`	additional arguments passed to axis.

Details

axis.mult automates the process of displaying an axis with a multiplier applied to the tick values. By default it will divide the default axis tick labels by mult and place mult.label where xlab or ylab would normally appear. Thus the plot call should set the relevant label to an empty string in such cases. It is simplest to call plot with axes=FALSE and then display the box and any standard axes before calling axis.mult.

Value

nil

Note

While axis.mult will try to display an axis on any side, the top and right margins will require adjustment using par for axis.mult to display properly.

Examples

plot(1:10 * 0.001, 1:10 * 100,axes = FALSE, xlab = "", ylab = "",
  main = "Axis multipliers")
 box()
 axis.mult(1, mult = 0.001)
 axis.mult(2, mult = 100)
