Detailed Description

Holds the data of one single data point for QCPGraph.

The stored data is:

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

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

Constructor & Destructor Documentation

QCPGraphData() [1/2]

QCPGraphData::QCPGraphData

(

)

Constructs a data point with key and value set to zero.

QCPGraphData() [2/2]

QCPGraphData::QCPGraphData	(	double	key,
		double	value
	)

Constructs a data point with the specified key and value.

Member Function Documentation

sortKey()

double QCPGraphData::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.

fromSortKey()

static QCPGraphData QCPGraphData::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.

sortKeyIsMainKey()

static static bool QCPGraphData::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.

mainKey()

double QCPGraphData::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 QCPGraphData::mainValue ( ) const

inline

Returns the value 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.

valueRange()

QCPRange QCPGraphData::valueRange ( ) const

inline

Returns a QCPRange with both lower and upper boundary set to value 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.
