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()

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()

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()

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()

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()
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()

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.
