drag.on(typenames, [listener]) If listener is specified, sets the event listener for the specified typenames and returns the drag behavior. 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. When

selection.attrs(values) A convenience method on top of selection.attr for setting multiple attributes. If the specified values is an object, the values may be specified either as strings or functions. For example: selection.attrs({foo: "foo-value", bar: function(d) { return d.bar; }}); If a value is a constant, all elements are given the same attribute value; otherwise, if a value is a function, the function is evaluated for each selected element, in order, being passed the current datum (d),

interval.floor(date) Returns a new date representing the latest interval boundary date before or equal to date. For example, timeDay.floor(date) typically returns 12:00 AM local time on the given date. This method is idempotent: if the specified date is already floored to the current interval, a new date with an identical time is returned. Furthermore, the returned date is the minimum expressible value of the associated interval, such that interval.floor(interval.floor(date) - 1) returns the

arc.padAngle([angle]) If angle is specified, sets the pad angle to the specified function or number and returns this arc generator. If angle is not specified, returns the current pad angle accessor, which defaults to: function padAngle() { return d && d.padAngle; } The pad angle is converted to a fixed linear distance separating adjacent arcs, defined as padRadius * padAngle. This distance is subtracted equally from the start and end of the arc. If the arc forms a complete circle o

request.on(type[, listener]) If listener is specified, sets the event listener for the specified type and returns this request instance. If an event listener was already registered for the same type, the existing listener is removed before the new listener is added. If listener is null, removes the current event listener for the specified type (if any) instead. If listener is not specified, returns the currently-assigned listener for the specified type, if any. The type must be one of the fo

d3.geoConicConformal() d3.geoConicConformalRaw(phi0, phi1) The conic conformal projection. The parallels default to [30°, 30°] resulting in flat top. See also conic.parallels.

partition.padding([padding]) If padding is specified, sets the padding to the specified number and returns this partition layout. If padding is not specified, returns the current padding, which defaults to zero. The padding is used to separate a node’s adjacent children.

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.timeInterval(floor, offset[, count[, field]]) Constructs a new custom interval given the specified floor and offset functions and an optional count function. The floor function takes a single date as an argument and rounds it down to the nearest interval boundary. The offset function takes a date and an integer step as arguments and advances the specified date by the specified number of boundaries; the step may be positive, negative or zero. The optional count function takes a start date a

tile.size([size]) If size is specified, sets this tile layout’s size to the specified two-element array of numbers [width, height] and returns this tile layout. If size is not specified, returns the current layout size. This is a convenience method equivalent to setting the extent to [[0, 0], [width, height]].
