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.
- See also:
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
Member Data Documentation
Time of the sample, usually a number representing a specific interval - like a day.
