bokeh.models.arrow_heads

Models for various kinds of arrow heads that can be added to Arrow annotations.

class ArrowHead(**kwargs)

Bases: bokeh.models.annotations.Annotation

Base class for arrow heads.

Note

This is an abstract base class used to help organize the hierarchy of Bokeh model types. It is not useful to instantiate on its own.
