xticks beyond those in DataFrame

I found myself looking at trends and wanting to pseudo forecast them into the future by simply mouse over-ing at some future date. However, since that date is not in the DataFrame, there is neither tick marks nor the x,y display that is shown for all of the data.

I hacked together a solution by modifying the IntegerIndexDateTimeFormatter, which solves both tick marks and the x,y display.

I thought I'd post here in case it is useful to anyone else. I'm not sure if I know mplfinance well enough to know if it breaks other things or if it is worth creating a pull request.

Commencez par la modification de IntegerIndexDateTimeFormatter dans la branche dates_bynd_data liée et reproduisez les graduations manquantes ainsi que l’affichage x,y pour les dates postérieures au DataFrame. Comparez le comportement avec les graphiques existants et vérifiez si la modification préserve la gestion actuelle des dates dans la plage; le travail est terminé lorsque les dates futures peuvent être inspectées sans casser le formatage existant.
