Opis szczegółowy

Holds the data of one single data point for QCPFinancial.

The stored data is:

  • key: coordinate on the key axis of this data point (this is the mainKey and the sortKey)
  • open: The opening value at the data point (this is the mainValue)
  • high: The high/maximum value at the data point
  • low: The low/minimum value at the data point
  • close: The closing value at the data point

The container for storing multiple data points is QCPFinancialDataContainer. It is a typedef for QCPDataContainer with QCPFinancialData as the DataType template parameter. See the documentation there for an explanation regarding the data type's generic methods.
