Re-export from the scales package.
Can be used to overwrite the default locale of date labels.
label_date_short()only labels part of the dates, when they change, i.e. year is only labelled when the year changes.See
scales::label_date()andscales::label_date_short()for more details.
Usage
label_date(format = "%Y-%m-%d", tz = "UTC", locale = NULL)
label_date_short(
format = c("%Y", "%b", "%d", "%H:%M"),
sep = "\n",
leading = "0",
tz = "UTC",
locale = NULL
)Arguments
- format
For
label_date()andlabel_time()a date/time format string using standard POSIX specification. Seestrptime()for details.For

A string to replace leading zeroes with. Can be
""to disable leading characters or"\u2007"for figure-spaces.
