Contour legend entry does not show line color

plotly.js
1

I’m plotting contours without markers, and the legend doesn’t show the line style. Scatter traces on the same plot with markers show the line. I can’t find any other options for styling the legend entry.

It seems to be working in this demo.
Am I missing something?

I guess I never got the notification, but I did the same search and arrived at my own question again. The key syntax that fixed it was “coloring” : “none”, then applying the color in the “line object”:

"contours": {"coloring": "none"},
"line": {
   "color": "red",
   "width": 4,
   },
