# timeSeriesGroupRateSum {#agg-function-timeseriesgroupratesum}
|
||
|
|
|
||
|
|
Syntax: `timeSeriesGroupRateSum(uid, ts, val)`
|
||
|
|
|
||
|
|
Similarly to [timeSeriesGroupSum](timeseriesgroupsum.md), `timeSeriesGroupRateSum` calculates the rate of time-series and then sum rates together.
|
||
|
|
Also, timestamp should be in ascend order before use this function.
|
||
|
|
|
||
|
|
Applying this function to the data from the `timeSeriesGroupSum` example, you get the following result:

``` text

|
|
[(2,0),(3,0.1),(7,0.3),(8,0.3),(12,0.3),(17,0.3),(18,0.3),(24,0.3),(25,0.1)]
|

```
