d3.timeHours(start, stop[, step]) d3.utcHours(start, stop[, step]) Aliases for timeHour.range and utcHour.range.

d3.timeDays(start, stop[, step]) d3.utcDays(start, stop[, step]) Aliases for timeDay.range and utcDay.range.

d3.timeFormat(specifier) An alias for locale.format on the default locale.

d3.timeFormatDefaultLocale(definition) Equivalent to d3.timeFormatLocale, except it also redefines d3.timeFormat, d3.timeParse, d3.utcFormat and d3.utcParse to the new locale’s locale.format, locale.parse, locale.utcFormat and locale.utcParse. If you do not set a default locale, it defaults to U.S. English.

d3.ticks(start, stop, count) Returns an array of approximately count + 1 uniformly-spaced, nicely-rounded values between start and stop (inclusive). Each value is a power of ten multiplied by 1, 2 or 5. See also tickStep and linear.ticks. Note that due to the limited precision of IEEE 754 floating point, the returned values may not be exact decimals; use d3-format to format numbers for human consumption. Ticks are inclusive in the sense that they may include the specified start and stop value

d3.tile() Constructs a layout for determining which 256x256 quadtree tiles to display in a rectangular viewport. var tile = d3.tile();

d3.timeDay d3.utcDay Days (e.g., February 7, 2012 at 12:00 AM); typically 24 hours. Days in local time may range from 23 to 25 hours due to daylight saving.

d3.tickStep(start, stop, count) Returns the difference between adjacent tick values if the same arguments were passed to ticks: a nicely-rounded value that is a power of ten multiplied by 1, 2 or 5. Note that due to the limited precision of IEEE 754 floating point, the returned value may not be exact decimals; use d3-format to format numbers for human consumption.

d3.thresholdSturges(values) Returns the number of bins according to Sturges’ formula; the input values must be numbers.

d3.symbolWye The Y-shape symbol type.
