Linear aggregation（线性聚合（Linear aggregation））¶
Takes multiple time series, either from a transform table column, a grouped time series plot, an object set with time series, or manual inputs, and computes a linear aggregation of the time series set over time. You can add a linear aggregation from the Next Actions menu by selecting Visualize > Linear aggregation. Note that while a rolling or periodic aggregate transforms aggregate over a single time series, the linear aggregation aggregates across multiple time series.

Input type¶
Time series, time series group, or transform table
Output type¶
Time series
Examples¶
Usage information¶
| Functionality | Availability |
|---|---|
| Standard Quiver card | Supported |
| Transform table transform | Supported* |
* In the transform table, this transform is called "time series group linear aggregation", and must be performed on a time series group column (result of a group by transform).

线性聚合（Linear aggregation）¶
接收多个时间序列（可来自转换表列、分组时间序列图、含时间序列的对象集或手动输入），并计算这些时间序列随时间变化的线性聚合结果。您可以通过 下一步操作（Next Actions） 菜单选择 可视化 > 线性聚合（Visualize > Linear aggregation） 来添加线性聚合。请注意，滚动聚合或周期聚合是对单个时间序列进行聚合，而线性聚合则是对多个时间序列进行跨序列聚合。

输入类型¶
时间序列、时间序列组或转换表
输出类型¶
时间序列

* 在转换表中，此转换称为"时间序列组线性聚合"，且必须对时间序列组列（分组转换的结果）执行。
