Box plot with custom quartiles being inconsistent with upperfence parameter

In the documentation: https://plotly.com/python/box-plots/#box-plot-with-precomputed-quartiles

There is a code sample with upperfence parameter set to [5,6,7] which doesn't really make sense because the q3 values are [7,8,9] and I think the upperfence of a box plot can't be lower than the q3 values. However, the provided example returns a boxplot with all upperfences set to 9, which is the maximum-minimum upperfence value possible for the provided boxplots. I think this behavior is not desirable because difficult to understand.

I think it would be better to raise an error. If you prefer not to raise an error, I guess a better option would be to set the upperfence to the minimum possible values in each boxplot.

Have a nice day.

Inizia con l’esempio di documentazione collegato, «Box plot with precomputed quartiles», e traccia il modo in cui vengono gestiti i valori q3 e upperfence. Confronta l’output documentato con il comportamento richiesto, quindi definisci e verifica un risultato coerente per i valori upperfence non validi; l’esempio di documentazione non dovrebbe più essere fonte di confusione.
