|

气泡图地理区域上方会显示不同大小的圆点,圆形面积与其在数据集中的数值会成正比。
|
||||
|
||||
## 使用
|
||||
|
||||
气泡图通过PointLayer对象实例化,shape 设置成 **circle**
|
||||
|
||||
```javascript
|
||||
|
||||
const bubble =
|
||||
new PointLayer()
|
||||
.source(data)
|
||||
.shape(circle)
|
||||
.size('mag',[0, 25])
|
||||
.color('red')
|
||||
.style({
|
||||
opacity: 0.3,
|
||||
strokeWidth: 1
|
||||
})
|
||||
```
|
||||
## tips
|
||||
|
||||
目前style的配置项只支持全局设置,不支持数据映射。
|
||||
|
||||
如果 opacity 设置为 0.3 则所有的气泡都是 0.3
|
||||
|
||||
style方法如果没有设置 stroke, 默认于气泡的填充色相同

title: 3D 柱图
|

order: 5
|

---
|
||||
3D柱图地理区域上方会显示不同高度的柱体,主题的高度与其在数据集中的数值会成正比。
|
||||
|
||||
## 使用
|
||||
|
||||
3D柱图通过 PointLayer对象实例化,将shape设置成不同的3Dshape
|
||||
### shape
|
||||
|
||||
3D Shape 支持
|
||||
|
||||
- cylinder
|
||||
- triangleColumn
|
||||
- hexagonColumn
|
||||
- squareColumn
|
||||
|
||||
### size
|
||||
|
||||
3D柱图size 需要设置三个维度 [w, l, z]
|
||||
- w 宽
|
||||
- l 长
|
||||
- z 高度
|
||||
|
||||
size设置成常量
|
||||
|
||||
```
|
||||
layer.size([2,2,3])
|
||||
```
|
||||
size 回调函数设置
|
||||
|
||||
```
|
||||
layer.size('unit_price', h => {
|
||||
return [ 6, 6, h / 500 ];
|
||||
})
|
||||
```
|
||||
|
||||
|
||||
|
||||
```javascript
|
||||
|
||||
const column = new PointLayer({})
|
||||
.source(data)
|
||||
.shape('name', [
|
||||
'cylinder',
|
||||
'triangleColumn',
|
||||
'hexagonColumn',
|
||||
'squareColumn'
|
||||
])
|
||||
.size('unit_price', h => {
|
||||
return [ 6, 6, h / 500 ];
|
||||
})
|
||||
.color('name', [ '#5B8FF9', '#70E3B5', '#FFD458', '#FF7C6A' ])
|
||||
.style({
|
||||
opacity: 1.0
|

散点图通过PointLayer对象实例化
|
||||

color 可以设置根据数据映射
|

new PointLayer()
|

在地理区域上放置不同图片作为符号,通常表示不同地理要素分布情况
|

|
||||
|

|
||||
## 使用
|
||||
|
||||
符号图 通过PointLayer对象实例化,将shape设置成图片符号
|
||||
|
||||
### shape
|
||||
|
||||
通过scene addImage 方法
|
||||
|
||||
addImage()
|
||||
参数:
|
||||
- id 图片的id,
|
||||
- url 图片的url
|
||||
|
||||
```javascript
|
||||
scene.addImage(
|
||||
'00',
|

'https://gw.alipayobjects.com/zos/basement_prod/604b5e7f-309e-40db-b95b-4fac746c5153.svg'
|
||||
);
|
||||
|
||||
⚠️ 符号图的ID不能与点图层已有shape名称相同,比如不能设置 circle
|
||||
|
||||
```
|
||||
|
||||
符号图需要把shape设置成图片的id,同样符号图shape也支持数据映射
|
||||
|
||||
```javascript
|
||||
const scatter =
|
||||
new PointLayer()
|
||||
.source(data)
|
