Spline annotation is used to draw cubic Bezier curves. In the overlay below, the spline is in green and the control points are shown by the light grey line:
points = [(-0.3, -0.3), (0,0), (0.25, -0.25), (0.3, 0.3)] overlay = hv.Spline((points,)) * hv.Curve(points) overlay.opts( opts.Curve(color='#D3D3D3'), opts.Spline(color='green', line_width=6))
Note that the Bokeh
Spline does not support the same control codes as the matplotlib version which is why the codes are supplied above as an empty list.
