Hello folks!

I am having some troubles when plotting a QwtPlotCurve with time stamps on the x axis when drawing plots on an embedded system.
The QwtPlotCurve uses internally a representation with a series of QPointF, the QPointF again uses qreal's for the coordinates. While the qreal is a typedef for 'double' on Desktop systems, qreal is defined to be 'float' on ARM based systems. The problem is now that I can not store UNIX timestamps in a float without data loss because there are 'only' 23 bits available (double has 52 bits).

My question is now if there is any other curve implementation which will support a series of e.g. QPair<unsigned long, double> instead of QPointF? Or do I have to implement a custom curve?

Best regards,
michael
