   Public Member Functions
       QwtOHLCSample (double time=0.0, double open=0.0, double high=0.0,
           double low=0.0, double close=0.0)
       QwtInterval boundingInterval () const
           Calculate the bounding interval of the OHLC values.
       bool isValid () const
           Check if a sample is valid.

   Public Attributes
       double time
       double open
           Opening price.
       double high
           Highest price.
       double low
           Lowest price.
       double close

       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

           isValid()

       Definition at line 220 of file qwt_samples.h.

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

       o low <= high

       o low <= open <= high

       o low <= close <= high

       Returns
           True, when the sample is valid

       Definition at line 203 of file qwt_samples.h.

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