Creating a waterfall plot with the spectrogram

[stilgar]

A QwtDoubleRect is a QRectF. From the Qwt docs:

typedef QPointF 	QwtDoublePoint
typedef QSizeF 	QwtDoubleSize
typedef QRectF 	QwtDoubleRect

typedef QPointF 	QwtDoublePoint
typedef QSizeF 	QwtDoubleSize
typedef QRectF 	QwtDoubleRect

Yes, it is true, but my question was not exactly what I meant. The real question was: the third parameter shouldn't be area instead of rect?
