QwtDateScaleDraw understading

[Stank]

This is not the solution i was aiming for but it worked :

I solved my scale problem at the same time as my format problem using this method :
(original post in french) : http://www.developpez.net/forums/d10...-axe-absisses/
overight the QwtText label function :

class TimeScaleDraw: public QwtScaleDraw
{
	virtual QwtText label(double v) const    
	{		
		QDateTime t = QDateTime::fromTime_t((int)v);	//cf fromTime_t	
		return t.toString("dd/MM/yyyy");    
	}
}

class TimeScaleDraw: public QwtScaleDraw
{
	virtual QwtText label(double v) const    
	{		
		QDateTime t = QDateTime::fromTime_t((int)v);	//cf fromTime_t	
		return t.toString("dd/MM/yyyy");    
	}
}

To copy to clipboard, switch view to plain text mode 

and then

myPlot->setAxisScaleDraw(QwtPlot::xBottom, new TimeScaleDraw());
myPlot->setAxisScale(QwtPlot::xBottom, min, max);

myPlot->setAxisScaleDraw(QwtPlot::xBottom, new TimeScaleDraw());
myPlot->setAxisScale(QwtPlot::xBottom, min, max);

To copy to clipboard, switch view to plain text mode 

where min and max are values in second since epoch.

Thanks for your time
