%%opts ErrorBars (line_width=2 line_color='darkblue')
%%opts Points    [invert_axes=False] (color='darkred' size=6)
import holoviews as hv
import numpy as np

x=['a','b','c','d','e']
points = [(x[i], 5*np.random.rand()) for i in range(5)]
errors = [points[i]+(np.random.rand()/2,) for i in range(5)]

h1 = hv.Points(points)
h2 = hv.ErrorBars(errors)
h2*h1

Hello, I have just stambled upon this error. Is there any workaround I can use before it is fixed?

We are testing against master. It may also come down to the Bokeh version though. In any case there will be new HoloViews and Bokeh releases very soon.
