Set Cartesian axis attributes via template

[archmoj]

Commit 5f8b280 addresses #4667 i.e. to set axis type, rangebreaks and tickformatstops from
template.

@plotly/plotly_js

I think we should leave #4671 alone for now please... this code already works as desired for e.g. annotations. Check out this Python example: https://plot.ly/python/templates/#including-tuple-elements-in-a-theme

In JS, it appears those were not working before | after.

@nicolaskruchten@alexcjohnson am I missing something?

[nicolaskruchten]

This works for me with the production bundle: https://codepen.io/nicolaskruchten/pen/wvaENrm?editors=0010

@alexcjohnson I'll let you judge the safety of these changes, keeping in mind that I would rather keep existing bugs in the interests of getting 1.53 and 1.54 done ASAP and not introducing subtle new bugs. For 1.53 we just need rangebreaks and hovermode = "* unified" to work with templates IMO.

[alexcjohnson]

@archmoj the way templates interact with container arrays is a bit subtle as it contains features for both defaults for all array items and overrides for specific items (which may not be at the same index in the array), but in general it works. Take a look at the original templates PR #2761, esp. this test and the arrayTemplater function

Please use those for context before deciding what's a bug.

[nicolaskruchten]

Ah, with respect to your before/after: you need to set name for that to work... https://plot.ly/javascript/reference/#layout-annotations-items-annotation-name

[alexcjohnson]

This isn't quite right... [] is truthy, also axTemplate.rangeBreaks items will extend the array if it contains named items.

Can we instead do:

handleArrayContainerDefaults(...);if(containerOut.rangebreaks.length){// setConvert and gl / splom check}else{deletecontainerOut.rangebreaks;}

Same for tickformatstops

[archmoj]

Good idea. Done in f824902.

💃 Love it. Thanks for catching these!
