Description

Add a clear description of the feature that you're requesting.

Please add dynamic sorting of the tooltip legend ordering for hovermode='x unified' mode, so that when the user move the mouse over the chart, the legend showing up in the tooltip block reflects the ascending order of the legend value for that specific x value.

Why should this feature be added?

Provide an argument for why this feature should be added. We can't add everything, so this will help us determine what gets worked on. Please also consider creating a PR and adding the feature yourself. Help is always appreciated.

This will drastically improve the intuitiveness of the tooltip block information, making direct comparison between different trace at a certain x value much more easier.

Mocks/Designs

Please add any mocks or designs you might have for the feature.

Notes

Add info here that doesn't fit in the other sections.

Aucun fichier, test ou point d’entrée n’est indiqué. Commencez par localiser l’implémentation de hovermode='x unified' et l’ordre de la légende de l’infobulle, puis déterminez comment les valeurs peuvent être triées dynamiquement à chaque position x. Le travail est terminé lorsque l’infobulle reflète l’ordre croissant des valeurs de la légende pour la valeur x survolée, sans modifier les autres modes de survol.
