Extends

• THING.Heatmap

Members

auxiliaryLine :Boolean

是否显示辅助等值线

Default Value:

• true

Example

idwLayer.auxiliaryLine = false;

data

数据源

Overrides:

• THING.Heatmap#data

Example

heatMap.data = [[-20, 0, 35],[-20, 10, 37]];

exponent :Number

计算权重使用的幂值(仅IDWMap生效)

Default Value:

• 2

Example

idwLayer.exponent=3

readonly extent :Object

获取热力图数据范围

Overrides:

• THING.Heatmap#extent

extrudeHeight :Number

热力图拔高 代表热力图热度最高位置拔起的高度 单位米

Overrides:

• THING.Heatmap#extrudeHeight

Default Value:

• 1

Example

heatMap.extrudeHeight = 100

gradient :Object

热力图色带

Overrides:

• THING.Heatmap#gradient

Example

heatMap.gradient= {
		0: "rgb(0,0,255)",
		0.33: "rgb(0,255,0)",
		0.66: "rgb(255,255,0)",
		1.0: "rgb(255,0,0)",
	  }

isoline :Boolean

是否显示等值线

Default Value:

• false

Example

idwLayer.isoline = false;

mask :Object

获取/设置 遮罩

Overrides:

• THING.Heatmap#mask

readonly maskShape :Object3D

基于maskShape作为展示热力图的对象 这里需要注意maskShape是一个xz平面的片,非地球模式下生效

Overrides:

• THING.Heatmap#maskShape

maxValue :Number

获取/设置最大值

Overrides:

• THING.Heatmap#maxValue

minMaxRatio :Array.<Number>

获取/设置剔除比例最大最小值,默认[0,1]是不剔除

Overrides:

• THING.Heatmap#minMaxRatio

minValue :Number

获取/设置最小值

Overrides:

• THING.Heatmap#minValue

mosaic :Mosaic

马赛克效果设置

Overrides:

• THING.Heatmap#mosaic

Example

heatMap.mosaic = {enable:true,size:1};

radius :Number

插值图点位数据的影响半径 单位米(仅IDWMap生效)

Overrides:

• THING.Heatmap#radius

Default Value:

• 5

Example

idwMap.radius = 10

renderType

热力图渲染模式 支持THING.HeatmapRenderType.Plane 普通2d热力图 与THING.HeatmapRenderType.Mesh 3d热力图对于非地球上使用mask的情况 目前使用3d热力图效果不明显

Overrides:

• THING.Heatmap#renderType

transparent :Boolean

无热度的区域是否透明

Overrides:

• THING.Heatmap#transparent

Default Value:

• false

Example

heatMap.transparent=true

Methods

setData(data)

设置数据

Parameters:

Name	Type	Description
data	Array.<Array.<Number>>	[[x1 , y1 , value1],[x2 , y2 , value2]]

Overrides:

• THING.Heatmap#setData

Example

heatMap.setData([[0,0,10],[0,1,12],[0,2,11]]);//等同于heatMap.data = [[0,0,10],[0,1,12],[0,2,11]];

setIsoline(contourSpacingValue, lineThickness)

设置等值线参数

Parameters:

Name	Type	Description
contourSpacingValue	Number	等值线间距
lineThickness	Number	等值线宽度系数(不代表实际像素值)

updateMapViewExtent()

更新地图上热力图的绘制范围

Overrides:

• THING.Heatmap#updateMapViewExtent
