Public Member Functions
	QCPStatisticalBoxData ()
	Constructs a data point with key and all values set to zero.
	QCPStatisticalBoxData (double key, double minimum, double lowerQuartile, double median, double upperQuartile, double maximum, const QVector< double > &outliers=QVector< double >())
	Constructs a data point with the specified key, minimum, lowerQuartile, median, upperQuartile, maximum and optionally a number of outliers.
double	sortKey () const
	Returns the key member of this data point.
double	mainKey () const
	Returns the key member of this data point.
double	mainValue () const
	Returns the median member of this data point.
QCPRange	valueRange () const
	Returns a QCPRange spanning from the minimum to the maximum member of this statistical box data point, possibly further expanded by outliers.

Static Public Member Functions
static QCPStatisticalBoxData	fromSortKey (double sortKey)
	Returns a data point with the specified sortKey.
static bool	sortKeyIsMainKey ()
	Since the member key is both the data point key coordinate and the data ordering parameter, this method returns true.

Detailed Description

Holds the data of one single data point for QCPStatisticalBox.

The stored data is:

• key: coordinate on the key axis of this data point (this is the mainKey and the sortKey)

• minimum: the position of the lower whisker, typically the minimum measurement of the sample that's not considered an outlier.

• lowerQuartile: the lower end of the box. The lower and the upper quartiles are the two statistical quartiles around the median of the sample, they should contain 50% of the sample data.

• median: the value of the median mark inside the quartile box. The median separates the sample data in half (50% of the sample data is below/above the median). (This is the mainValue)

• upperQuartile: the upper end of the box. The lower and the upper quartiles are the two statistical quartiles around the median of the sample, they should contain 50% of the sample data.

• maximum: the position of the upper whisker, typically the maximum measurement of the sample that's not considered an outlier.

• outliers: a QVector of outlier values that will be drawn as scatter points at the key coordinate of this data point (see QCPStatisticalBox::setOutlierStyle)

The container for storing multiple data points is QCPStatisticalBoxDataContainer. It is a typedef for QCPDataContainer with QCPStatisticalBoxData as the DataType template parameter. See the documentation there for an explanation regarding the data type's generic methods.

fromSortKey()

static QCPStatisticalBoxData QCPStatisticalBoxData::fromSortKey ( double  sortKey )

inlinestatic

Returns a data point with the specified sortKey.

All other members are set to zero.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

mainKey()

double QCPStatisticalBoxData::mainKey ( ) const

inline

Returns the key member of this data point.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

mainValue()

double QCPStatisticalBoxData::mainValue ( ) const

inline

Returns the median member of this data point.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

sortKey()

double QCPStatisticalBoxData::sortKey ( ) const

inline

Returns the key member of this data point.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

sortKeyIsMainKey()

static static bool QCPStatisticalBoxData::sortKeyIsMainKey ( )

inlinestatic

Since the member key is both the data point key coordinate and the data ordering parameter, this method returns true.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

valueRange()

QCPRange QCPStatisticalBoxData::valueRange ( ) const

inline

Returns a QCPRange spanning from the minimum to the maximum member of this statistical box data point, possibly further expanded by outliers.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.
