Equally spaced breaks
Useful for numeric, date, and date-time scales.
breaks_width(width, offset = 0)
width |
Distance between each break. Either a number, or for date/times, a single string of the form "n unit", e.g. "1 month", "5 days". Unit can be of one "sec", "min", "hour", "day", "week", "month", "year". |
offset |
Use if you don't want breaks to start at zero |
demo_continuous(c(0, 100))
demo_continuous(c(0, 100), breaks = breaks_width(10))
demo_continuous(c(0, 100), breaks = breaks_width(20, -4))
demo_continuous(c(0, 100), breaks = breaks_width(20, 4))
# This is also useful for dates
one_month <- as.POSIXct(c("2020-05-01", "2020-06-01"))
demo_datetime(one_month)
demo_datetime(one_month, breaks = breaks_width("1 week"))
demo_datetime(one_month, breaks = breaks_width("5 days"))
# This is so useful that scale_x_datetime() has a shorthand:
demo_datetime(one_month, date_breaks = "5 days")
# hms times also work
one_hour <- hms::hms(hours = 0:1)
demo_time(one_hour)
demo_time(one_hour, breaks = breaks_width("15 min"))
demo_time(one_hour, breaks = breaks_width("600 sec"))Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
