staxlab: Place staggered or angled labels on an axis

In plotrix: Various Plotting Functions

Place staggered or angled labels on an axis

Description

Places labels on an axis in a regular staggered order or at an angle

Usage

 staxlab(side=1,at,labels,nlines=2,top.line=0.5,line.spacing=0.8,
  srt=NULL,ticklen=0.03,adj=1,...)

Arguments

side	axis on which to place the labels, as in ‘⁠axis⁠’
at	where to place the labels in user units, as in ‘⁠axis⁠’
labels	text strings
nlines	How many lines to use to stagger the labels.
top.line	Distance from the axis to place the first line of text.
line.spacing	Spacing between lines of text labels.
srt	Text rotation.
ticklen	Proportion of plot height in user units to place text below the plot.
adj	horizontal adjustment of the labels.
...	Additional arguments to be passed to ‘⁠mtext⁠’ or ‘⁠text⁠’.

Value

nil

Note

This function is mainly useful when either long axis labels or a large number of labels are to be placed without overlapping. It staggers the labels along the axis specified. The user may wish to increase the space beneath the plot using ‘⁠mar⁠’ before calling ‘⁠staxlab⁠’. It is probably only useful on the bottom or left side of the plot.

If ‘⁠srt⁠’ is not NULL, the labels will be rotated ‘⁠srt⁠’ degrees and placed below the plot. This method will only place labels at the bottom. Note that this option only works on the lower and left axes.
