Properties

Property	Modifier	Type	Description	Inherited from
binned	readonly	number	Experimental Samples that fell in some cell.	Histogram2dCalc.binned
bounds	readonly	ContourBounds	Experimental The contoured area, from the first to the last grid point (linear coordinates).	ContourField.bounds
cellPoints	readonly	Uint32Array	Experimental	Histogram2dCalc.cellPoints
cellStart	readonly	Uint32Array	Experimental Samples of each cell: cellPoints[cellStart[c] … cellStart[c + 1]] (sample indices).	Histogram2dCalc.cellStart
coloring	readonly	ContourColoring	Experimental contours.coloring ('none' for constraint contours, which color with line.color).	ContourField.coloring
constraint	readonly	ContourConstraint | undefined	Experimental Set for constraint contours (contours.type: 'constraint').	ContourField.constraint
histfunc	readonly	HistFunc	Experimental The aggregation actually used (count without z / marker.color).	Histogram2dCalc.histfunc
levels	readonly	ContourLevels	Experimental The levels: contours.start/end/size, or the constraint's one or two levels.	ContourField.levels
mask?	readonly	ContourRegion	Experimental Where the data is, when gaps are not connected (contour with connectgaps: false): rings in linear coordinates for the nonzero rule. paths are already clipped to it; fills are clipped when drawn.	ContourField.mask
nx	readonly	number	Experimental	Histogram2dCalc.nx
ny	readonly	number	Experimental	Histogram2dCalc.ny
paths	readonly	readonly readonly ContourPath[][]	Experimental Per level: its contour lines (smoothed), in linear coordinates.	ContourField.paths
regions	readonly	readonly ContourRegion[] | undefined	Experimental coloring: 'fill': per level, the region z ≥ level as rings for the nonzero fill rule, in linear coordinates (painted in level order over the background). Constraint contours: the one shaded region (none for =).	ContourField.regions
x	readonly	Histogram2dAxisBins	Experimental	Histogram2dCalc.x
y	readonly	Histogram2dAxisBins	Experimental	Histogram2dCalc.y
z	readonly	Float64Array	Experimental Cell values, row-major (z[j * nx + i]); NaN for empty avg / min / max cells.	Histogram2dCalc.z
zExtent	readonly	readonly [number, number]	Experimental Finite extent of z ([NaN, NaN] without values).	Histogram2dCalc.zExtent
zFilled	readonly	Float64Array	Experimental z with empty cells filled (what is contoured, and drawn by coloring: 'heatmap').	ContourField.zFilled
