Holds the data of one single data point for QCPCurve.
Więcej...
#include <qcustomplot.hh>
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.

Constructs a curve data point with the specified t, key and value.
| 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.
| 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.
| 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.
| 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.
| 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.
| QCPRange QCPCurveData::valueRange |
( |
| ) |
const |
|
inline |
Returns a QCPRange with both lower and upper boundary set to value of this data point.
