'bins' keyword argument ignored in histogram

Hi,

It seems like setting the number of bins through the bins keyword argument in histograms does nothing.

Let’s take an example in the Holoviews demos:

import holoviews as hv
from holoviews import opts
hv.extension('bokeh')
from bokeh.sampledata.autompg import autompg

autompg_ds = hv.Dataset(autompg)
hist = autompg_ds.hist(dimension='mpg', groupby='cyl', bin_range=(9, 46), bins=40, adjoin=False)
hist.opts(opts.Histogram(alpha=0.9, width=600))

Setting bins to 40 or 10 or 100 does not change the output. Note that I encounter the same behavior when using histogram() from holoviews.operation.element.

Or maybe I’m getting something wrong?

Config:

• Holoviews 1.13.4
• Jupyter notebook with bokeh backend
• Python 3.8
• Browser: Chromium / Firefox
• OS: CentOS 7

A little surprised that setting bins to an integer does not raise an error as it should only support

I was surprised too, but it’s actually a long-standing issue with ParamOverrides https://github.com/holoviz/param/issues/85

The command to use is num_bins. Sorry for the late answer.
