达人涨粉趋势返回一个账号的粉丝数随日期变化的序列 `follower_trend`，外加窗口内的平均粉丝量 `average_follower_count`。谈合作前用它看达人的粉丝是稳步增加、突然跳升还是停滞，再对照账号的热度判断是否对得上。

请求只需要 `user_id`，没有时间窗参数；采样窗口、每个日期有没有数据、变化的原因，接口都不说明。`dimension_code` 是画像维度的编码，要按维度看粉丝构成，用粉丝画像那一页。`user_id` 用账号的 secUid，示例里直接填了用户主页链接。

## FAQ

### 涨粉趋势能看出为什么涨吗？

看不出。`follower_trend` 只是粉丝数随日期的序列，接口不说明变化原因。想找原因，把涨幅大的日期对到这个账号的用户内容发布时间，或者读那几天视频下的评论。

### `average_follower_count` 有什么用？

它是趋势窗口内的平均粉丝量，可以当基线：序列里哪些日期高于它、哪些低于它，一眼就能分出来。比较两个达人的体量时，也可以直接比这个数。

### 涨粉趋势和同类达人对比怎么选？

要看一个账号的粉丝随时间怎么变，用趋势这一页；要知道新增粉丝量在同类账号里排什么位置，用同类达人对比，它给对比窗口内的平均新增粉丝量和百分位，没有逐日序列。两页的 `user_id` 填法相同，同一个 secUid 可以先后传给两边。
