Plot continuous data versus time

y_time(df, x = pm_axis_time(), y, xunit = "hr", yname = NULL,
  xs = list(), ys = list(), log = FALSE, xby = NULL, ...)

Arguments

df	data frame to plot
x	character name for x-axis data
y	character name for y-axis data
xunit	used to form x-axis title
yname	used to form y-axis title
xs	see `defx`
ys	see `defy`
log	if `TRUE`, y-axis will be log-transformed
xby	interval for breaks on x-axis (time)
...	passed to `scatt`

A single plot.

This function is intented for internal use.

When the y-axis label needs a unit, include it in the yname specification.

Since this function creates a scatter plot, both the x and y columns must be numeric.

The xby argument is provided for convenience to set breaks for time scales.
