dt

Gives access to the datapoint’s duration

Every datapoint in a stream has a duration. This value is hidden when performing operations in PipeScript, since all operations are performed on a datapoint’s d (data) field. To permit processing based upon duration in PipeScript, the dt transform exposes the datapoint’s duration.

Remember that raw datapoints are in the form:

[
  {
    "t": 123456.23,
    "d": 4,
    "dt": 80.0
  }
]

When performing transforms, d==4 will return true, since we operate on the “d” (data) field. But the duration is 80.0, so the transform dt will result in the following datapoint:

[
  {
    "t": 123456.23,
    "d": 80.0,
    "dt": 80.0
  }
]
