Can't set parcoords color array as strings

[slishak]

Potentially related to #3595

I adapted the codepen from there, setting the color array to a list of strings, but they all come up as black:

That's correct, parcoords only support numeric colorscales at the moment.

One may simply use colorscale for this. Here is a simple codepen.
In respect to parcoords implementation which is optimised for speed and the 256 texture limit, it is not recommended to give every single line different colour.
Here is another example with 256 different colours.

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
