Template issues

[chriddyp]

• Parcoords line colors not updating with template and react. The line should be blue but it’s still hotpink: https://codepen.io/chriddyp/pen/EeQoGE
• I couldn’t get the carpet grid colors to update. I might be doing something wrong here with the API though: https://codepen.io/chriddyp/pen/BOYJGy Fixed in: Use Template.newContainer in carpet axis defaults #3095
• Similarly I couldn’t get the radar grid lines to updates: https://codepen.io/chriddyp/pen/qMxpJy Fixed in: Use Template.newContainer in polar axis defaults #3092

Potentially related to: #3032

Some info:

Parcoords line colors:

The template propagates fine during react, the problem happens during the parcoords update. We can replicate this bug using restyle and relayout: https://codepen.io/etpinard/pen/YJVrKm

Carpet grid colors:

No bug here (I think). You' need to include startlinecolor and endlinecolor or color in your template: e.g. https://codepen.io/etpinard/pen/ZqKXOo?editors=1010

Polar grid lines:

This line:

plotly.js/src/plots/polar/layout_defaults.js

Lines 52 to 56 in 5c4094f

	// Note: does not need template propagation, since coerceAxis is still
	// based on the subplot-wide coerce function. Though it may be more
	// efficient to make a new coerce function, then we *would* need to
	// propagate the template.
	var axOut = contOut[axName] = {};

is off. In fact, we do need to propagate the template so that the attributes that use coerce2 can reach into _template. This should be an easy fix, PR incoming.

So I've been able to get the carpet grid colors working in the carpet trace directly, but they don't seem to be coming through from the data portion of the template.

Does my template data specification here look right?

Good 👁️ @jonmmease , fixed in #3095

All the "real" template issues listed here have been resolved.

The parcoords problems are now in -> #3101

Closing.
