concat

temporaldata.concat(objs, sort=True)

Concatenates multiple time series objects into a single object.

Parameters:

• objs (List[Union[IrregularTimeSeries, RegularTimeSeries]]) – List of time series objects to concatenate.

• sort (bool, optional) – Whether to sort the resulting time series by timestamps. Only applies to IrregularTimeSeries. Defaults to True.

Returns:

The concatenated time series object.

Return type:

Union[IrregularTimeSeries, RegularTimeSeries]

Raises:

• ValueError – If objects are not all of the same type or don’t have matching keys.

• NotImplementedError – If concatenation is not implemented for the given object type.

Example

>>> import numpy as np
>>> from temporaldata import IrregularTimeSeries, Interval, concat

>>> ts1 = IrregularTimeSeries(
...     timestamps=np.array([0.0, 1.0]),
...     values=np.array([1.0, 2.0]),
...     domain="auto",
... )
>>> ts2 = IrregularTimeSeries(
...     timestamps=np.array([2.0, 3.0]),
...     values=np.array([3.0, 4.0]),
...     domain="auto",
... )

>>> ts_concat = concat([ts1, ts2])
>>> ts_concat
IrregularTimeSeries(
  timestamps=[4],
  values=[4]
)
>>> ts_concat.timestamps
array([0., 1., 2., 3.])
