d3.timeHour d3.utcHour Hours (e.g., 01:00 AM); 60 minutes. Note that advancing time by one hour in local time can return the same hour or skip an hour due to daylight saving.

d3.interpolateBlues(t) d3.schemeBlues Given a number t in the range [0,1], returns the corresponding color from the “Blues” sequential color scheme represented as an RGB string.

diagram The computed Voronoi diagram returned by voronoi has the following properties: edges - an array of edges. cells - an array of cells, one per input point; a cell may be null for a coincident point.

d3.easeBackOut(t) Reverse anticipatory easing; equivalent to 1 - backIn(1 - t).

selection.datum([value]) Gets or sets the bound data for each selected element. Unlike selection.data, this method does not compute a join and does not affect indexes or the enter and exit selections. If a value is specified, sets the element’s bound data to the specified value on all selected elements. If the value is a constant, all elements are given the same datum; otherwise, if the value is a function, then the function is evaluated for each selected element, in order, being passed the

pie.sortValues([compare]) If compare is specified, sets the value comparator to the specified function and returns this pie generator. If compare is not specified, returns the current value comparator, which defaults to descending value. The default value comparator is implemented as: function compare(a, b) { return b - a; } If both the data comparator and the value comparator are null, then arcs are positioned in the original input order. Otherwise, the data is sorted according to the dat

continuous.tickFormat([count[, specifier]]) Returns a number format function suitable for displaying a tick value, automatically computing the appropriate precision based on the fixed interval between tick values. The specified count should have the same value as the count that is used to generate the tick values. An optional specifier allows a custom format where the precision of the format is automatically set by the scale as appropriate for the tick interval. For example, to format percen

d3.interpolateYlGnBu(t) d3.schemeYlGnBu Given a number t in the range [0,1], returns the corresponding color from the “YlGnBu” sequential color scheme represented as an RGB string.

d3.area() Constructs a new area generator with the default settings.

d3.deviation(array[, accessor]) Returns the standard deviation, defined as the square root of the bias-corrected variance, of the given array of numbers. If the array has fewer than two values, returns undefined. An optional accessor function may be specified, which is equivalent to calling array.map(accessor) before computing the standard deviation. This method ignores undefined and NaN values; this is useful for ignoring missing data.
