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

To copy to clipboard, switch view to plain text mode 

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?

Thx

I'm using Qt-4.7.2 and qwt-6.0.0 and I need a waterfall plot.
If you have a implementation and you want share it, I would be pleased and it would save me much time.

Many thanks.
