simulation.on(typenames, [listener]) If listener is specified, sets the event listener for the specified typenames and returns this simulation. If an event listener was already registered for the same type and name, the existing listener is removed before the new listener is added. If listener is null, removes the current event listeners for the specified typenames, if any. If listener is not specified, returns the first currently-assigned listener matching the specified typenames, if any. W

d3.selectorAll(selector) Given the specified selector, returns a function which returns all descendants of this element that match the specified selector. This method is used internally by selection.selectAll. For example, this: var div = selection.selectAll("div"); Is equivalent to: var div = selection.selectAll(d3.selectorAll("div"));

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

d3.axisRight(scale) Constructs a new right-oriented axis generator for the given scale, with empty tick arguments, a tick size of 6 and padding of 3. In this orientation, ticks are drawn to the right of the vertical domain path.

pow.copy() See continuous.copy.

continuous.copy() Returns an exact copy of this scale. Changes to this scale will not affect the returned scale, and vice versa.

map.keys() Returns an array of string keys for every entry in this map. The order of the returned keys is arbitrary.

d3.csvFormatRows(rows) Equivalent to dsvFormat(",").formatRows.

time.domain([domain]) See continuous.domain.

d3.zip(arrays…) Returns an array of arrays, where the ith array contains the ith element from each of the argument arrays. The returned array is truncated in length to the shortest array in arrays. If arrays contains only a single array, the returned array contains one-element arrays. With no arguments, the returned array is empty. d3.zip([1, 2], [3, 4]); // returns [[1, 3], [2, 4]]
