Interface: BarCalc

Experimental

Bar calcdata. Index-aligned typed arrays, one entry per bar.

Properties

Property	Modifier	Type	Description
bars	public	StackOutput	Experimental Layout and stacking result (updated by crossTraceCalc).
base	readonly	Float64Array	Experimental User base per bar (calc space), 0 where unset.
ends	public	object	Experimental Bar ends (x, y linear): where error bars attach (center of the bar's far edge).
ends.x	public	Float64Array	-
ends.y	public	Float64Array	-
errorX	public	ErrorBarCalc | undefined	Experimental Error bars along x and y, at the bar ends (after stacking, as in Plotly).
errorY	public	ErrorBarCalc | undefined	Experimental
floor	public	boolean	Experimental Some bar starts at -Infinity (log axis without a positive base): draw it from the axis floor.
hasBase	readonly	Uint8Array	Experimental 1 where the user set a base for that bar.
length	readonly	number	Experimental
minSpacing?	readonly	number	Experimental A minimum position spacing (Plotly's width1): a histogram collapsed to one bin knows its bin width, which then sizes the bars. Unset for bars.
orientation	readonly	"v" | "h"	Experimental
overlayAlone?	readonly	boolean	Experimental In overlay mode, lay this trace out on its own, with its own position spacing (Plotly lays out every overlaid trace alone): overlaid histograms keep their own bin widths. Unset for bars, which share one layout.
period?	readonly	object	Experimental With xperiod (yperiod for horizontal bars): the period of each bar on the position axis (linear), which pos is aligned within. Hover along that axis catches a bar over its period (Plotly's bar/hover.js). Unset without a period.
period.ends	readonly	Float64Array	-
period.starts	readonly	Float64Array	-
pos	readonly	Float64Array	Experimental Positions (linear coordinates of the position axis); NaN where a bar cannot be placed.
positionValues?	readonly	ArrayLike<unknown>	Experimental The position of each bar as label and template value (%{label}, %{x}), when it is not the trace's position coordinate: a histogram's bin centers (calc space). Unset for bars.
posType	readonly	AxisType | undefined	Experimental Position-axis type, when known.
s0	public	Float64Array	Experimental Bar start / end on the size axis, linear. -Infinity: starts below a log axis.
s1	public	Float64Array	Experimental
size	readonly	Float64Array	Experimental Lengths in calc space of the size axis (ms on date axes, raw values on log axes).
sizeType	readonly	AxisType | undefined	Experimental Size-axis type, when known.
