Disable automatic sorting of the slices in the sunburst

[xanderwallace85]

Hi guys!

Would it be possible to add an option that disables the automatic sorting of the slices in the sunburst?
Thank you in advance!

Also see #4728 which is related.

+1 for this request so that plotly sunburst does not sort (apply magic) on the data provided.

I'm new to the plotly code base, but will try to find the code where sorting happens.

[thierryVergult]

In ./traces/sunburst/calc.js, sorting happens at

// TODO add way to sort by height also?
hierarchy.sort(function(a, b) { return b.value - a.value; });

Making that line conditional was solving my use case (no sorting).

Will try to add a configuration option, in line with branchvalues, to make this configurable.

Is there a preference for a name of the layout attribute to disable sorting on values? One option is to reuse +sort+, an attribute available for the pie chart. Another option is to make it sunburst specific, like sunburstnosort.

I think you could simply reuse sort for that.

sort: extendFlat({}, pieAttrs.sort, {
  dflt: true
})

Please note the dflt for sunburst (and treemap) should be set to true as their default.
