weldx.TimeSeries#

class weldx.TimeSeries(data, time=None, interpolation=None, reference_time=None)#

Describes the behaviour of a quantity in time.

Construct a TimSeries.

Parameters:

data (Union[Quantity, MathematicalExpression]) – Either a pint.Quantity or a weldx.MathematicalExpression. If a mathematical expression is chosen, it is only allowed to have a single free variable, which represents time.
time (Union[DatetimeIndex, datetime64, List[str], Time, TimedeltaIndex, Quantity, timedelta64, Timestamp, str, TimeDependent, None]) – An instance of pandas.TimedeltaIndex if a quantity is passed and ‘None’ otherwise.
interpolation (Optional[str]) – A string defining the desired interpolation method. This is only relevant if a quantity is passed as data. Currently supported interpolation methods are: ‘step’, ‘linear’.

Methods

`interp_time`	Interpolate the TimeSeries in time.
`plot`	Plot the `TimeSeries`.

Attributes

`data`	Return the data of the TimeSeries.
`data_array`	Return the internal data as 'xarray.DataArray'.
`interpolation`	Return the interpolation.
`is_discrete`	Return `True` if the time series is described by discrete values.
`is_expression`	Return `True` if the time series is described by an expression.
`reference_time`	Get the reference time.
`shape`	Return the shape of the TimeSeries data.
`time`	Return the data's timestamps.
`units`	Return the units of the TimeSeries Data.
