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.

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 5551 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 5554 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 5555 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 5550 of file qcustomplot.h.

sortKeyIsMainKey()

static 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 5552 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.
