allow varying marker.line.width in 3DScatter plot

Varying marker.line.width works nicely in go.Scatter, you're able to specify a different outline width for each point:

works

import plotly.graph_objs as go

x = [1,2,3]
y = [1,2,3]

fig = go.Figure(
          data=[go.Scatter(x=x, y=y,
            mode='markers',
            marker=dict(size=30,
              color=['rgba(100,0,0,.5)','rgba(0,100,0,.5)','rgba(0,0,100,.5)'],
              line=dict(color=['rgb(0,100,0)','rgb(0,0,100)','rgb(100,0,0)'], width=[3,6,9])
            ),
          )])

fig.show()

However in go.Scatter3d this functionally does not work:

import plotly.graph_objs as go

x = [1,2,3]
y = [1,2,3]
z = [1,2,3]

fig = go.Figure(
          data=[go.Scatter3d(x=x, y=y,z=z,
            mode='markers',
            marker=dict(size=30,
              color=['rgba(100,0,0,.5)','rgba(0,100,0,.5)','rgba(0,0,100,.5)'],
              line=dict(color=['rgb(0,100,0)','rgb(0,0,100)','rgb(100,0,0)'], width=[3,6,9])
            ),
          )])

fig.show()

ValueError: Invalid value of type 'builtins.list' received for the 'width' property of scatter3d.marker.line Received value: [3, 6, 9] The 'width' property is a number and may be specified as: - An int or float in the interval [0, inf]

This different functionality is actually reflected in the documentation, but additionally, passing a single value to data[type=scatter3d].marker.line.width does not actually change point outline widths; changing [3,6,9] in the above code to 20 or .5 results in the same graph.

It would be great if go.Scatter3d could behave the same as go.Scatter for this.

I'm using plotly 4.6.0 py_0 plotly
installed 05/05/20 using conda install -c plotly plotly

Inizia dall’implementazione di Scatter3d marker.line.width e confrontala con il comportamento funzionante di Scatter. Esegui gli esempi Python forniti per riprodurre sia l’errore di convalida del valore di lista sia il valore scalare inefficace; il lavoro è completato quando vengono accettate larghezze per punto e le larghezze scalari modificano visibilmente i contorni dei punti.
