Holds the data of one single data point for QCPCurve.
The stored data is:
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.
| QCPCurveData::QCPCurveData | ( | ) |
Constructs a curve data point with t, key and value set to zero.
| QCPCurveData::QCPCurveData | ( | double | t, |
| double | key, | ||
| double | value | ||
| ) |
Constructs a curve data point with the specified t, key and value.
|
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.
|
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.
|
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.
|
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.
|
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.
|
inline |
Returns a QCPRange with both lower and upper boundary set to value of this data point.
