Warning "Chart elements should only be supplied a single kdim"

[hyamanieu]

ALL software version info

latest holoviews 1.14.3 and anything used to build the doc: http://holoviews.org/reference/streams/bokeh/Selection1D_tap.html

Description of expected behavior and the observed behavior

This example from the doc should show no warning.
It shows:

WARNING:param.Scatter: Chart elements should only be supplied a single kdim
WARNING:param.Scatter: Chart elements should only be supplied a single kdim

It is hard to decipher where it is from.

My own model is also using a holoviews.stream object and since update, shows this very same warning. Previous version was 1.13.3.

Complete, minimal, self-contained example code that reproduces the issue

In the example it's because of this:

points = hv.Scatter(data, ['Date', 'r2'], ['block', 'id']).redim.range(r2=(0., 1))

which should be updated to:

points = hv.Scatter(data, 'Date', ['r2', 'block', 'id']).redim.range(r2=(0., 1))

Alright, i'll submit a PR for this example this week.
