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.
Open-High-Low-Close sample used in financial charts.
In financial charts the movement of a price in a time interval is often represented by the opening/closing prices and the lowest/highest prices in this interval.

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.
- Bounding interval
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
- True, when the sample is valid
