# heatmapLayer
### 简介
热力图图层,包含三种类型的,
- 方格热力图
将一组点数据按照等大小的正方形网格进行聚合,一个正方形网格代表网格内所有点的统计值。方格热力图特点以方格网布局。
- 六边形热力图
将一组点数据按照等大小的六边形网格进行聚合,一个六边形网格代表网格内所有点的统计值。蜂窝热力图特点以六边形热力图网格布局
- 经典热力图
⚠️ 网格热力图和蜂窝热力图需要对数据聚合处理使用之前需要在source方法设置数据聚合方法
### source
热力图只支持点数据作为数据源
布局方法 通过source的 tansforms属性配置
- type  数据聚合类型 grid、hexagon
- size  网格半径 单位 米
- field  聚合字段
- method 聚合方法  count,max,min,sum,mean5个统计维度
```javascript
layer.source(data, {
parser: {
type: 'csv',
x: 'lng',
y: 'lat'
},
transforms:[
{
type: 'grid',
size: 15000,
field:'v',
method:'sum'
}
],
}
```
### shape
不同类型热力图shape支持
| | 2D | 3d |
| --- | --- | --- |
| 网格格热力图 | circle,triangle,square,heaxgon | cylinder,triangleColumn,hexagonColum,squareColumn |
| 蜂窝热力图 | circle,triangle,square,heaxgon | circle,triangle,square,heaxgon |
| 普通热力图 | heatmap | heatmap |
热力图布局下只shape方法只支持常量的可视化。
```javascript
HeatmapLayer.shape('square');
HeatmapLayer.shape('hexagon');
// 默认类型可以不设置
```
### size
当前版本 shape 为gridhexagon不需要设置 size 映射
default 类型需要设置size映射 详细参数见[Size](https://www.yuque.com/antv/l7/layer#size)
**size(field,values) **
- field: 热力图权重字段
- values: 数据映射区间 热力图显示 [0, 1] 效果最佳
```javascript
HeatmapLayer.size ('field', [0, 1])
```
### color
default heatMap 类型不需设置 color映射
color 配置项同 [**color**](https://www.yuque.com/antv/l7/layer#color)
### style
grid hexagon 可以通过style 设置透明度
default热力图需要通过style配置参数热力图参数
- intensity   全局热力权重   推荐权重范围 1-5
- radius  热力半径单位像素
- rampColors 色带参数
- colors  颜色数组
- positions 数据区间
```javascript
HeatmapLayer.style({
intensity: 3,
radius: 20,
rampColors: {
colors: [ 'rgba(33,102,172,0.0)', 'rgb(103,169,207)', 'rgb(209,229,240)', 'rgb(253,219,199)', 'rgb(239,138,98)', 'rgb(178,24,43,1.0)' ],
positions: [ 0, 0.2, 0.4, 0.6, 0.8, 1.0 ]
}
})
```
### 完整代码示例
#### 普通热力图
```javascript
// 测试数据 url https://gw.alipayobjects.com/os/basement_prod/08c6ea00-dc5f-4bb0-b0b5-52bde5edf0a3.json
HeatmapLayer({
zIndex: 2
})
.source(data)
.size('mag', [ 0, 1 ]) // weight映射通道
.style({
intensity: 3,
radius: 20,
rampColors: {
colors: [ 'rgba(33,102,172,0.0)', 'rgb(103,169,207)', 'rgb(209,229,240)', 'rgb(253,219,199)', 'rgb(239,138,98)', 'rgb(178,24,43,1.0)' ],
positions: [ 0, 0.2, 0.4, 0.6, 0.8, 1.0 ]
}
})
```
#### 网格热力图
```javascript
var layer = scene.HeatmapLayer({
zIndex: 2
})
.source(data, {
parser: {
type: 'csv',
x: 'lng',
y: 'lat'
},
transforms:[
{
type: 'grid',
size: 15000,
field:'v',
method:'sum'
}
]
})
.shape('grid')
.style({
coverage: 0.8
})
.color('count',
["#002466","#105CB3","#2894E0","#CFF6FF","#FFF5B8","#FFAB5C","#F27049","#730D1C"])
```
#### 六边形热力图
```javascript
var layer = scene.HeatmapLayer({
zIndex: 2
}).
souce(data,{
parser:{
type:'csv',
x:lng,
y:lat,
},
transforms:[
{
type:'hexgon',
size:1500,
field:'count',
operation: 'sum',
}
]
})
.shape('hexgon')
.size(1000)
.color('sum')
.style({

- type  数据聚合类型 grid、hexagon
- size  网格半径 单位 米
- field  聚合字段
- method 聚合方法  count,max,min,sum,mean5个统计维度
```javascript
layer.source(data, {
parser: {
type: 'csv',
x: 'lng',
y: 'lat'
},
transforms:[
{
type: 'grid',
size: 15000,
field:'v',
method:'sum'
}
],
}
```
### shape
不同类型热力图shape支持
| | 2D | 3d |
| --- | --- | --- |
| 网格格热力图 | circle,triangle,square,heaxgon | cylinder,triangleColumn,hexagonColum,squareColumn |
| 蜂窝热力图 | circle,triangle,square,heaxgon | circle,triangle,square,heaxgon |
| 普通热力图 | heatmap | heatmap |
热力图布局下只shape方法只支持常量的可视化。
```javascript
HeatmapLayer.shape('square');
HeatmapLayer.shape('hexagon');
// 默认类型可以不设置
```
### size
当前版本 shape 为gridhexagon不需要设置 size 映射
default 类型需要设置size映射 详细参数见[Size](https://www.yuque.com/antv/l7/layer#size)
**size(field,values) **
- field: 热力图权重字段
- values: 数据映射区间 热力图显示 [0, 1] 效果最佳
```javascript
HeatmapLayer.size ('field', [0, 1])
```
### color
default heatMap 类型不需设置 color映射
color 配置项同 [**color**](https://www.yuque.com/antv/l7/layer#color)
### style
grid hexagon 可以通过style 设置透明度
default热力图需要通过style配置参数热力图参数
- intensity   全局热力权重   推荐权重范围 1-5
- radius  热力半径单位像素
- rampColors 色带参数
- colors  颜色数组
- positions 数据区间
```javascript
HeatmapLayer.style({
intensity: 3,
radius: 20,
rampColors: {
colors: [ 'rgba(33,102,172,0.0)', 'rgb(103,169,207)', 'rgb(209,229,240)', 'rgb(253,219,199)', 'rgb(239,138,98)', 'rgb(178,24,43,1.0)' ],
positions: [ 0, 0.2, 0.4, 0.6, 0.8, 1.0 ]
}
})
```

## 方法
### source
数据源为layer设置数据 source(data,config)
- data {geojson|json|csv}
      源数据
- config  可选 数据源配置项
- parser 数据解析默认是解析层geojson
- transforms [transformtransform ]  数据处理转换 可设置多个
 parser和 transforms [见source文档](https://www.yuque.com/antv/l7/source)
```javascript
layer.source(data, {
parser: {
type: 'csv',
x: 'lng',
y: 'lat'
},
transforms:[
{
type: 'map',
callback:function(item){
const [x, y] = item.coordinates;
item.lat = item.lat*1;
item.lng = item.lng*1;
item.v = item.v *1;
item.coordinates = [x*1,y*1];
return item;
}
},
{
type: 'hexagon',
size: 6000,
field:'v',
method:'sum'
}
]
})
```
###
### scale
cscle('field', scaleConfig)
(field: string, scaleConfig: object)
为指定的数据字段进行列定义,返回 layer 实例。
- `field` 字段名。
- `scaleConfig` 列定义配置,对象类型,可配置的属性如下:
```javascript
{
type: "linear" // 指定数据类型可声明的类型为identity、linear、cat、time、timeCat、log、pow, quantile,quantize
}
```
### size
将数据值映射到图形的大小上的方法。
**注意:** 
不同图层的 size 的含义有所差别:
- point 图形的 size 影响点的半径大小和高度;
- line, arc, path 中的 size 影响线的粗细,和高度;
- polygon size 影响的是高度
```javascript
pointLayer.size(10); // 常量
pointLayer.size('type'); // 使用字段映射到大小
pointLayer.size('type', [ 0, 10 ]); // 使用字段映射到大小,并指定最大值和最小值
pointLayer.size('type', (type) => { // 回调函数
if(type === 'a') {
return 10;
}
return 5;
});
```
#### size(value
传入数字常量,如 `pointLayer.size(20)`
#### size(field)
根据 field 字段的值映射大小,使用默认的`最大值 max:10` 和`最小值 min: 1`。
#### size(field, callback)
使用回调函数控制图形大小。
- `callback`: function 回调函数。
```javascript
pointLayer.size('age', (value) => {
if(value === 1) {
return 5;
}
return 10;
});
```
### color
将数据值映射到图形的颜色上的方法。
```javascript
layer.color('red'); // 常量颜色
layer.color('type'); // 对 type 字段进行映射,使用内置的颜色
layer.color('type', [ 'red', 'blue' ]) // 指定颜色
layer.color('type', (type) => { // 通过回调函数
if (type === 'a') {
return 'red';
}
return 'blue';
});
layer.color('type*value', (type, value) => { //多个参数,通过回调函数
if (type === 'a' && value > 100) {
return 'red';
}
return 'blue';
});
```
#### color(value)
参数:`value` string
只支持接收一个参数value 可以是:
- 映射至颜色属性的数据源字段名,如果数据源中不存在这个字段名的话,则按照常量进行解析,这个时候会使用 L7 默认提供的颜色。
- 也可以直接指定某一个具体的颜色值 color如 '#fff', 'white','rgba(255,0,0,0.5)' ,rgb(255,0,1) 等。
示例
```javascript
layer.color('name') // 映射数据字段
layer.color('white') // 指定颜色
```
#### color(field, colors)
参数:
- `field`: stringfield 为映射至颜色属性的数据源字段名,也支持指定多个参数。
-  `colors`: string | array | function
colors 的参数有以下情况: 如果为空,即未指定颜色的数组,那么使用内置的全局的颜色;如果需要指定颜色,则需要以数组格式传入,那么分类的颜色按照数组中的颜色确定。对于颜色的分配顺序。
```javascript
layer.color('name'); // 使用默认的颜色
layer.color('name', [ 'red', 'blue' ]); // 使用传入的指定颜色
```
- colors 如果是回调函数,则该回调函数的参数为对应字段的数值,具体使用如下,当 color 映射为多个字段时,参数按照字段声明的顺序传入:
```javascript
layer.color('gender', (value) => {
if(value === 1) {
return 'red'
}
return 'blue';
});
layer.color('gender*age', (gender, age) => {
if(age === 20 && gender ==' 男' ) {
return 'red'
}
return 'blue';
});
```

- line 绘制填充图描边 不支持数据映射
- extrude 对填充图3D拉伸 不支持数据映射
``` javascript
PolyonLayer.shape('fill');
PolyonLayer.shape('line').size(1); // size 表示线宽度
PolyonLayer.shape('extrude'); // size 表示高度
```

# 使用方法
L7 提供三种使用方式CDN、Submodule 以及 React 组件。
## 通过 CDN 使用
首先在 `<head>` 中引入 L7 CDN 版本的 JS 和 CSS 文件:
```html
<head>
<script src='https://api.l7/v2.0.0-beta/l7.js'></script>
<link href='https://api.l7/v2.0.0-beta/l7.css' rel='stylesheet' />
</head>
```
如果使用 Mapbox还需要额外引入 Mapbox 的 JS 和 CSS 文件,这一步可以参考 [Mapbox 文档](https://docs.mapbox.com/mapbox-gl-js/overview/#quickstart)
```html
<head>
<script src='https://api.tiles.mapbox.com/mapbox-gl-js/v1.5.0/mapbox-gl.js'></script>
<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v1.5.0/mapbox-gl.css' rel='stylesheet' />
<!-- 上一步引入的 L7 JS 和 CSS -->
</head>
```
⚠️高德采用异步加载,因此不需要引入任何额外静态文件。
然后在 `<body>` 中定义一个容器并设置一个 `id`。通过全局 `L7` 这个命名空间可以获取场景 `L7.Scene` 和图层 `L7.PolygonLayer`
⚠️需要获取高德或者 Mapbox 的使用 token 并传入 `L7.Scene` 的构造函数,获取方式如下:
* 高德地图开发者 Key [申请方法](https://lbs.amap.com/dev/key/)
* [Mapbox Access Tokens](https://docs.mapbox.com/help/how-mapbox-works/access-tokens/#creating-and-managing-access-tokens)
## 通过 Submodule 使用
首先通过 `npm/yarn` 安装 `@l7/scene``@l7/layers`
```bash
npm install --save @l7/scene @l7/layers
// or
yarn add @l7/scene @l7/layers
```
然后就可以使用其中包含的场景和各类图层:
```typescript
import { Scene } from '@l7/scene';
import { PolygonLayer } from '@l7/layers';
(async function() {
// 获取数据
const response = await fetch(
'https://gw.alipayobjects.com/os/basement_prod/d2e0e930-fd44-4fca-8872-c1037b0fee7b.json',
);
const data = await response.json();
// 创建场景
const scene = new Scene({
center: [110.19382669582967, 50.258134],
id: 'map',
pitch: 0,
style: 'dark',
type: 'amap',
zoom: 3,
token: 'pg.xxx', // 高德或者 Mapbox 的 token
});
// 创建图层
const layer = new PolygonLayer({});
layer
.source(data)
.size('name', [0, 10000, 50000, 30000, 100000])
.color('name', [
'#2E8AE6',
'#69D1AB',
'#DAF291',
'#FFD591',
'#FF7A45',
'#CF1D49',
])
.shape('fill')
.style({
opacity: 0.8,
});
// 添加图层到场景中
scene.addLayer(layer);
// 渲染场景
scene.render();
})();
```
最后在 `<head>` 中引入 L7 CDN 版本的 CSS 文件:
```html
<head>
<link href='https://api.l7/v2.0.0-beta/l7.css' rel='stylesheet' />
</head>
```
L7 目前的文档都通过这种方式使用,可以参考项目中的 stories
* [高德地图](https://github.com/antvis/L7/blob/next/stories/MapAdaptor/components/AMap.tsx)
* [Mapbox](https://github.com/antvis/L7/blob/next/stories/MapAdaptor/components/Mapbox.tsx)
## [WIP] React
React 组件待开发,目前可以暂时以 Submodule 方式使用:
```tsx
import { Scene } from '@l7/scene';
import { PolygonLayer } from '@l7/layers';
import * as React from 'react';
export default class AMap extends React.Component {
private scene: Scene;
public componentWillUnmount() {
this.scene.destroy();
}
public async componentDidMount() {
const response = await fetch(
'https://gw.alipayobjects.com/os/basement_prod/d2e0e930-fd44-4fca-8872-c1037b0fee7b.json',
);
const scene = new Scene({
center: [110.19382669582967, 50.258134],
id: 'map',
pitch: 0,
style: 'dark',
type: 'amap',
zoom: 3,
token: 'pg.xxx', // 高德或者 Mapbox 的 token
});
const layer = new PolygonLayer({});
layer
.source(await response.json())
.size('name', [0, 10000, 50000, 30000, 100000])
.color('name', [
'#2E8AE6',
'#69D1AB',
'#DAF291',
'#FFD591',
'#FF7A45',
'#CF1D49',
])
.shape('fill')
.style({
opacity: 0.8,
});
scene.addLayer(layer);
scene.render();
this.scene = scene;
}
public render() {
return (
<div
id="map"
style={{
position: 'absolute',
top: 0,
left: 0,
right: 0,
bottom: 0,
}}
/>
);
}
}
```
⚠️组件 Unmount 时需要通过 `scene.destroy()` 手动销毁场景。

# Source
### 概述
source 地理数据处理模块主要包含数据解析parser),和数据处理(transform);
**parser:**
不同数据类型处理成统一数据格式。矢量数据包括 GeoJON, CSVJson等不同数据格式栅格数据包括RasterImage数据。将来还会支持瓦片格式数据。
**transform**
数据转换,数据统计,网格布局,数据聚合等数据操作。
## API
### parser
空间数据分矢量数据和栅格数据两大类
- 矢量数据 支持 csvgeojsonjson 三种数据类型
- 栅格数据 支持 imageRaster
#### geojson
[geojson](https://www.yuque.com/antv/l7/dm2zll) 数据为默认数据格式,可以
不需要设置parser 参数
```javascript
layer.source(data)
```
#### json
json 不是标准的地理数据结构,因此需要设置对应的经纬度字段
**点数据**
x: 经度字段
y: 纬度字段
```javascript
const data = [{
lng:112.345,
lat:30.455,
value: 10
},{
 lng:114.345,
lat:31.455,
value: 10
 }
]
layer.source(
data,
{
parser: {
type:'json',
x:'lng',
y:'lat',
}
})
```
**线段数据**

parser:{
type:'json',
x:'lng1',
y:'lat1' ,
    x1:'lng1',
y1:'lat2' ,
}
}
})
```
**面数据**

}
})
```
### transforms
目前支持三种数据处理方法 mapgridhexagon transform配置项
- type 数据处理类型

#### map
数据处理支持自定义callback函数
- callback:function 回调函数
```javascript
layer.source(data, {
transforms:[
{
type: 'map',
callback:function(item){
const [x, y] = item.coordinates;
item.lat = item.lat*1;
item.lng = item.lng*1;
item.v = item.v *1;
item.coordinates = [x*1,y*1];
return item;
}
},
```
#### grid
生成方格网布局,根据数据字段统计,主要在网格热力图中使用
-  type: 'grid',
-  size: 网格半径
-  field: 数据统计字段
-  method:聚合方法  count,max,min,sum,mean5个统计维度
```javascript
layer.source(data, {
transforms:[
{
type: 'grid',
size: 15000,
field:'v',
method:'sum'
}
]
}
```
#### hexagon
