label_placer_isopycnal: Isopycnal label placement

In paleolimbot/ggoce: Plot 'oce' objects using 'ggplot2'

Description

Automatic labels placement is difficult and infrequently perfect. The default strategy to place labels uses a similar strategy to isoband::label_placer_minmax() except coordinates are constrained to a fraction of the visible area to keep labels from disappearing outside the plot bounds.

Usage

label_placer_isopycnal(
  placement = "t",
  padding = c(0.025, 0.025),
  bounds = c(padding[1], padding[2], 1 - padding[1], 1 - padding[2])
)

Arguments

placement	A string containing one or more of "t", "b", "l", or "r". See isoband::label_placer_minmax().
padding	A proportion of the plot (x, y) that should be excluded on all sides when choosing label center points. Ignored if bounds is specified.
bounds	A vector of xmin, ymin, xmax, ymax, outside which label centers should not exist.

Value

A function suitable as input to geom_isopycnal()'s label_placer argument.
