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.
