详细描述

Plot item for box-and-whisker (boxplot) visualization

QwtPlotBoxChart displays statistical distributions using the boxplot format:

Box body showing Q1-Q3 interquartile range
Median line inside the box
Whiskers extending to data range or calculated bounds
Outlier symbols for points outside whiskers

Supports multiple box styles (Rectangle, Diamond, Notch), horizontal/vertical orientation, and extensive customization.
