Silent failure to display scatter3d plot in mode lines+markers when line color is given

[ivirshup]

In mode lines+markers, if a line is specified with color from a numerical vector the plot silently fails. This happens regardless of whether I'm trying to display it in a notebook or write a file. Here's an example:

And here's a copy-able version of the relevant code:

import plotly.graph_objs as go
import numpy as np

x, y, z, c = np.random.random_sample((4, 10))
go.FigureWidget(data=[
    go.Scatter3d(x=x, y=y, z=z,
                 line=go.scatter3d.Line(color=c))
])

Thanks for another helpful report @ivirshup 🙂

I was able to reproduce the issue in Plotly.js directly and I've opened a corresponding issue there. You can follow plotly/plotly.js#2873 for updates.

Fixed in plotly.js by plotly/plotly.js#3341 (See plotly/plotly.js#3316 (comment)), released in plotly.js 1.43.0 and shipped in plotly.py 3.5.0.

import plotly.graph_objs as go
import numpy as np

x, y, z, c = np.random.random_sample((4, 10))
go.FigureWidget(data=[
    go.Scatter3d(x=x, y=y, z=z, mode='lines+markers',
                 line=go.scatter3d.Line(color=c),
                 marker={'color': 'blue'}
                )
])
