详细描述

Sample for box-and-whisker plot (boxplot) visualization

Contains all statistical values needed to render a boxplot: whisker endpoints, quartiles, median, and outlier count. Actual outlier values are stored separately in QwtBoxOutlierSample.

构造及析构函数说明

QwtBoxSample() [1/2]

QwtBoxSample::QwtBoxSample ( double  position = 0.0 )

inline

Default constructor

All values set to 0.0

QwtBoxSample() [2/2]

QwtBoxSample::QwtBoxSample ( double  position, double  whiskerLower, double  q1, double  median, double  q3, double  whiskerUpper  )

inline

Full constructor with all statistical values

参数

position	Position on the axis
whiskerLower	Lower whisker endpoint
q1	First quartile (25th percentile)
median	Median value (50th percentile)
q3	Third quartile (75th percentile)
whiskerUpper	Upper whisker endpoint

成员函数说明

boundingInterval()

QwtInterval QwtBoxSample::boundingInterval ( ) const

inline

Get bounding interval including whiskers

返回

Interval from whiskerLower to whiskerUpper

boxInterval()

QwtInterval QwtBoxSample::boxInterval ( ) const

inline

Get box body interval (Q1 to Q3)

返回

Interval from q1 to q3

isValid()

bool QwtBoxSample::isValid ( ) const

inline

Check if sample has valid ordering

Returns true if whiskerLower <= q1 <= median <= q3 <= whiskerUpper
