> mapgis-3d-analysis-aspect

## # 属性

### # `vueKey`

- 类型: `String`
- 可选
- 非侦听属性
- 默认值: `default`
- 描述: mapgis-web-scene 组件的 ID，当使用多个 mapgis-web-scene 组件时，需要指定该值，来唯一标识 mapgis-web-scene 组件，同时 mapgis-web-scene 插槽中的组件也需要传入相同的 vueKey，让组件知道应该作用于哪一个 mapgis-web-scene。

### # `vueIndex`

- 类型: `Number`
- 可选
- 非侦听属性
- 默认值: `(Math.random() * 100000000).toFixed(0)`随机计算值
- 描述: 当 mapgis-web-scene 插槽中使用了多个相同组件时，例如多个 mapgis-3d-igs-doc-layer 组件，用来区分组件的标识符。

### # `rampColors`

- 类型: `Array`
- 可选
- 侦听属性
- 描述: 坡向分析角度颜色数组
- 默认值:

    [
      { min: 0, max: 60, color: "rgba(244, 67, 54, 0.5)" },
      { min: 60, max: 120, color: "rgba(233, 30, 99, 0.5)" },
      { min: 120, max: 180, color: "rgba(156, 39, 176, 0.5)" },
      { min: 180, max: 240, color: "rgba(255, 235, 59, 0.5)" },
      { min: 240, max: 300, color: "rgba(96, 125, 139, 0.5)" },
      { min: 300, max: 360, color: "rgba(76, 175, 80, 0.5)" }
    ]

## # 方法

### # `analysis`

- Description: 坡向分析

### # `remove`

- Description: 移除坡向分析对象，移除坡向分析结果。

## # 事件

### # `@load`

- Description: 在 Aspect 加载完毕后发送该事件
- Payload 坡向分析对象

## # 示例

### # 非插槽方式
