Boxplot: Set Whisker options

Problem: Boxplot Whiskers can map to different data – sometimes this is +- 1.5 times the interquartil range, sometime the 5th and 95th percentile etc. In the box documentation, it is state that plotly uses the +-1.5 IQR as a standard. It is also stated that the boxpoints option allows other options, but seemingly boxpoints sets the displaying sof catterpoint and not of whiskers.

Proposed Solution: An option for setting what the whiskers mean. Candidates for this option would:

• n * IQR (for a +-1.5* the IQR, like the current default)
• nth percentiles (for something like a 5%/95% position)
• n*sd (for a +- 1 standard deviation position)

Or, if that option(s) already exists, a hint in the docuementation on how to set them.

Comienza con la documentación de boxplot enlazada en el issue y revisa cómo se describe la opción boxpoints existente. Determina si el comportamiento de los whiskers ya se puede configurar o si es necesaria una nueva opción; después, define y documenta el comportamiento compatible basado en IQR, percentiles o desviaciones estándar. Se considera terminado cuando la configuración de whiskers elegida funciona y la documentación de boxplot explica cómo utilizarla.
