guide_prism_offset | R Documentation |
This guide draws the axis only as wide as the outermost tick marks, similar to offset axes from Prism.
guide_prism_offset( title = waiver(), check.overlap = FALSE, angle = NULL, n.dodge = 1, order = 0, position = waiver() )
title |
A character string or expression indicating a title of guide.
If |
check.overlap |
silently remove overlapping labels, (recursively) prioritizing the first, last, and middle labels. |
angle |
Compared to setting the angle in |
n.dodge |
The number of rows (for vertical axes) or columns (for horizontal axes) that should be used to render the labels. This is useful for displaying labels that would otherwise overlap. |
order |
Used to determine the order of the guides (left-to-right, top-to-bottom), if more than one guide must be drawn at the same location. |
position |
Where this guide should be drawn: one of top, bottom, left, or right. |
Control the length of the axis by adjusting the breaks
argument in
scale_(x|y)_continuous()
or scale_(x|y)_discrete()
.
Returns a prism_offset guide class object.
