Experimental

heatmap calcdata.

Properties

Property	Modifier	Type	Description
fastSmoothing	readonly	boolean	Experimental Whether zsmooth: 'fast' applies: not on log axes nor uneven grids (Plotly turns it off there). See heatmapSmoothing.
nx	readonly	number	Experimental
ny	readonly	number	Experimental
pointOf	readonly	Int32Array<ArrayBufferLike> | undefined	Experimental Column data (1D z): per cell, the index of the point placed there (−1 for none), for hover and events. Undefined for 2D z, whose cells are [row, column].
smoothing?	readonly	HeatmapSmoothing	Experimental Smoothing hover assumes, overriding zsmooth (see heatmapSmoothing): contours set 'best' so labels sit on their grid points. Heatmaps leave it unset.
source?	readonly	object	Experimental 2D z re-indexed by the categories of an axis: the source row / column (of z as given, after transpose) of each grid row / column, −1 for none. Per-cell attributes (text, hovertext, customdata) are read there, so they follow their values. Undefined when the grid is z itself.
source.cols	readonly	Int32Array	-
source.rows	readonly	Int32Array	-
x	readonly	HeatmapAxisCells	Experimental
y	readonly	HeatmapAxisCells	Experimental
z	readonly	Float64Array	Experimental Cell values, row-major (z[j * nx + i]); NaN for gaps (after connectgaps).
zExtent	readonly	readonly [number, number]	Experimental Finite extent of z ([NaN, NaN] without values).
