breaks_pretty: Pretty breaks for date/times

In scales: Scale Functions for Visualization

Pretty breaks for date/times

Description

Uses default R break algorithm as implemented in pretty(). This is primarily useful for date/times, as extended_breaks() should do a slightly better job for numeric scales.

Usage

breaks_pretty(n = 5, ...)

Arguments

n	Desired number of breaks. You may get slightly more or fewer breaks that requested.
...	other arguments passed on to pretty()

Examples

one_month <- as.POSIXct(c("2020-05-01", "2020-06-01"))
demo_datetime(one_month)
demo_datetime(one_month, breaks = breaks_pretty(2))
demo_datetime(one_month, breaks = breaks_pretty(4))

# Tightly spaced date breaks often need custom labels too
demo_datetime(one_month, breaks = breaks_pretty(12))
demo_datetime(one_month,
  breaks = breaks_pretty(12),
  labels = label_date_short()
)
