weldx.core.TimeSeries

class weldx.core.TimeSeries(data, time=None, interpolation='linear')

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[None, TimedeltaIndex, Quantity]) – An instance of pandas.TimedeltaIndex if a quantity is passed and ‘None’ otherwise.

• interpolation (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

data_array	Return the internal data as ‘xarray.DataArray’.
interpolation	Return the interpolation.
shape	Return the shape of the TimeSeries data.
time	Return the data’s timestamps.
units	Return the units of the TimeSeries Data.
