Coordinates

DataArray is the base class in xdas. It is mainly composed of a N-dimensional array and a set of Coordinate objects that are gathered in a Coordinates dict-like object that can be accessed by the DataArray.coords attribute. Xdas comes with several flavors of Coordinate objects.

Type	Description	name	data
ScalarCoordinate	Used to label 0D dimensions	scalar	{"value": any}
DefaultCoordinate	Each value is equal to its index	default	{"size": int}
DenseCoordinate	Each index is mapped to a given value	dense	array-like[any]
InterpCoordinate	Values are interpolated linearly between tie points	interpolated	{"tie_indices": array-like[int], "tie_values": array-like[any]}
SampledCoordinate	Values are given as a multiple of a fixed sampling interval and several start values	sampled	{"tie_values": array-like[any], "tie_indices": array-like[int], "sampling_interval": any}

In the current state of the documentation, most coordinate information can be found on the Interpolated Coordinates page.
