Does anyone here have a strong opinion about this?
Should alignmentgroup and offsetgroup work across trace types? Or should we match bar and histogram and box and violin groupings separately?

Seems like making it work across trace types would be the most flexible - you can always just give different values to different trace types, which I guess is what the default would be. It's also probably what I'd expect as a user. It's an awfully weird use case, so not worth a huge effort, but if we omit it now and wanted to add it later it would be a breaking change.

Bars above for counts (say) and boxes below for distributions? Seems not that weird to me :) kinda useful actually!

Ah yeah good point. That would magically work if you have the same traces in each case, and in the same order... but break those assumptions (which could happen for good reasons) and you're back to manual alignment if we don't implement this cross-type.
... as well as across trace types (confirmed behavior) to do so: - add getAxisGroup axis_ids.js util - mv alignmentgroup and offsetgroup coerce calls to crossTraceDefaults

@plotly/plotly_js this PR is now @archmoj could you review this one? |

Excellent PR 💃 |

All the new mocks in a codepen: |

@etpinard thank you for this feature! One minor issue is that traces do not re-layout when toggled (reproduced in your "mocks"). So the user cannot turn-off traces using the legend to view the remaining traces at a larger size. |

@arlowhite thanks, would you mind filing a bug report at https://github.com/plotly/plotly.js/issues/new ? |
resolves #3402 - at least the part listed in #3402 (comment)
In brief, this PR add two attributes
alignmentgroupandoffsetgroupto bar, histogram, box and violin traces. These attributes allow to have more control over how the cross-trace offset and width values are computed. Examining thebar-alignment-offsetmock is probably the best way to grasp what these new attributes do.cc @plotly/plotly_js and @nicolaskruchten - it would be nice if you could take a 👀 at the new mocks, thanks!
some TODOs:
alignmentgroupandoffsetgroupon matching axes, once Implementing matching axes #3506 is mergedalignmentgroupandoffsetgroupshould do across trace types
