Datashading Error Parameter name clashes

[ariellalgilmore]

When datashading I get an error on a 1D graph when it's rendered and then continuously as the user zooms in and out.

Parameter name clashes for keys {'width', 'scale', 'height'}

I'm running holoviews 1.12.7 (datashader 0.9.0) and I still get

Parameter name clashes for keys {'y_range', 'x_range'}

while zooming.

For example using the code provided here:

import holoviews as hv
from holoviews.operation.datashader import datashade
import numpy as np

hv.extension('bokeh')  # otherwise defaults to matplotlib

points = hv.Points(np.random.multivariate_normal((0,0), [[0.1, 0.1], [0.1, 1.0]], (500000,)))

def filter_points(points, x_range, y_range):
    """Filter points by x/y range.
    
    To be used with .apply(filter_points, streams=)
    """
    if x_range is None or y_range is None:
        return points
    return points[x_range, y_range]

def hover_points(points, threshold=1000):
    """Filter points by threshold.
    
    Returns empty list if number of input points exceeds threshold.
    """
    if len(points) > threshold:
        return points.iloc[:0]
    return points

filtered = points.apply(filter_points, streams=[hv.streams.RangeXY(source=points)])
shaded = datashade(filtered, width=400, height=400)
hover = filtered.apply(hover_points)

layout = (shaded * hover.opts(tools=['hover'], alpha=0.1, hover_alpha=0.2, size=10))

renderer = hv.renderer('bokeh')
doc = renderer.server_doc(layout)

Thanks yeah, been meaning to look at that again. The warnings are completely inconsequential but still annoying.

This was fixed in #4119
