arrow#
- arrow(angle=None, length=None, ends=None, type=None)#
Describe arrows to add to a line.
- Parameters:
- anglefloat
The angle of the arrow head in degrees (smaller numbers produce narrower, pointer arrows). Essentially describes the width of the arrow head.
- lengthint
The length of the arrow head (px).
- ends{‘last’, ‘first’, ‘both’}
Indicating which ends of the line to draw arrow heads.
- type{‘open’, ‘closed’}
Indicating whether the arrow head should be a closed triangle.
- Returns:
FeatureSpecArrow object specification.
