The Arrow element is a type of annotation that points to a position on a visualization with optional text. It allows specifying an x- and y-position along with a label and a direction which may be one of '<', '>', 'v' and '^':

In [2]:
%%opts  Curve (color='#D3D3D3')
xs = np.linspace(-5,5,100)
ys = -(xs-2)**3
hv.Curve((xs,ys)) * hv.Arrow(0, 5, 'Inflection', 'v')
Out[2]:

Additionally we can pick between a number of different arrow styles including '-[', '->' and '<->':

In [3]:
np.random.seed(12)
points = hv.Points(np.random.randn(100, 2))
(points * hv.Arrow(2, points['y'].min(), 'Min', 'v', arrowstyle='-[') *
hv.Arrow(2, points['y'].max(), 'Max', '^', arrowstyle='-[')).redim.range(y=(-5, 5), x=(-3, 3))
