Description
Coming from plotly.py. Since this is about the plotly.graph_objects module, the issue is posted here.
Currently, only plotly.graph_objects.Scatter.marker, plotly.graph_objects.Scatter.marker.gradient and plotly.graph_objects.Scatter.marker.line supports assigning colors by arrays of color along with colorscale.
Could the same color-setting techniques be allowed for plotly.graph_objects.Scatter.line and plotly.graph_objects.Scatter.fillcolor as well?
p.s. Links to the current documentation:
- The following supports arrays of color with
colorscale:
- The following doesn't support arrays of color with
colorscale:

Research direction
Start by tracing how Scatter.marker, marker.gradient, and marker.line accept color arrays with a colorscale, then compare the handling of Scatter.line and fillcolor. Confirm the expected behavior in the existing documentation links and add coverage showing arrays work for both properties without breaking scalar colors.
