Detailed Description

       Open-High-Low-Close sample used in financial charts.

       opening/closing prices and the lowest/highest prices in this interval.

Constructor & Destructor Documentation

   QwtOHLCSample::QwtOHLCSample (double t = 0.0, double o = 0.0, double h = 0.0, double l = 0.0,
       double c = 0.0) [inline]
       Constructor

       Parameters:
           t Time value
           o Open value
           h High value
           l Low value
           c Close value

Member Function Documentation

   QwtInterval QwtOHLCSample::boundingInterval () const [inline]
       Calculate the bounding interval of the OHLC values. For valid samples the limits of this
       interval are always low/high.

       Returns:
           Bounding interval

       See also:
           isValid()

   bool QwtOHLCSample::isValid () const [inline]
       Check if a sample is valid. A sample is valid, when all of the following checks are true:

       • low <= high

       • low <= open <= high

       • low <= close <= high

       Returns:
           True, when the sample is valid

Member Data Documentation

   double QwtOHLCSample::time
       Time of the sample, usually a number representing a specific interval - like a day.
