Detailed Description

Holds the data of one single data point for QCPCurve.

The stored data is:

  • t: the free ordering parameter of this curve point, like in the mathematical vector (x(t), y(t)). (This is the sortKey)
  • key: coordinate on the key axis of this curve point (this is the mainKey)
  • value: coordinate on the value axis of this curve point (this is the mainValue)

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

Constructor & Destructor Documentation

◆ QCPCurveData() [1/2]

QCPCurveData::QCPCurveData ( )

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

Definition at line 22576 of file qcustomplot.cpp.

◆ QCPCurveData() [2/2]

QCPCurveData::QCPCurveData ( double t,
double key,
double value )

Constructs a curve data point with the specified t, key and value.

Definition at line 22586 of file qcustomplot.cpp.

Member Function Documentation

◆ fromSortKey()

static QCPCurveData QCPCurveData::fromSortKey ( double sortKey)
inlinestatic

Returns a data point with the specified sortKey (assigned to the data point's t member). 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.

Definition at line 5609 of file qcustomplot.h.

◆ mainKey()

double QCPCurveData::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.

Definition at line 5612 of file qcustomplot.h.

◆ mainValue()

double QCPCurveData::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.

Definition at line 5613 of file qcustomplot.h.

◆ sortKey()

double QCPCurveData::sortKey ( ) const
inline

Returns the t 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.

Definition at line 5608 of file qcustomplot.h.

◆ sortKeyIsMainKey()

static bool QCPCurveData::sortKeyIsMainKey ( )
inlinestatic

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

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

Definition at line 5610 of file qcustomplot.h.

◆ valueRange()

QCPRange QCPCurveData::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.

Definition at line 5615 of file qcustomplot.h.
