cf.DimensionCoordinate.direction

DimensionCoordinate.direction()

Return True if a coordinate is increasing, otherwise return False.

A coordinate is increasing if its coordinate values are increasing in index space.

The direction is inferred from one of, in order of precedence:

• The data array
• The bounds data array
• The positive property
• The units property (True if pressure, False otherwise or if missing)

Returns :

out : bool

Whether or not the coordinate is increasing.

Examples

>>> c.array
array([  0  30  60])
>>> c._get_direction()
True
>>> c.array
array([15])
>>> c.bounds.array
array([  30  0])
>>> c._get_direction()
False
