The VLine element is a type of annotation that marks a position along the x-axis. Here is a VLine marking the maximum of a quadratic curve:
In [2]:
xs = np.linspace(-5,5,100)
ys = -(xs-2)**2
overlay = hv.Curve((xs,ys)) * hv.VLine(xs[ys.argmax()])
overlay.opts(
opts.Curve(color='#D3D3D3'),
opts.VLine(color='red', line_width=6))
