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
