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 ‘^’.

xs = np.linspace(-5,5,100)
ys = -(xs-2)**3
curve = hv.Curve((xs,ys)).opts(color='#D3D3D3')
curve * hv.Arrow(0,10, 'Inflection', 'v')

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

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))

For full documentation and the available style and plot options, use hv.help(hv.Arrow).
