QwtText ScaleDraw::label ( double value ) const [virtual]

void ScaleDraw::labelFormat	(	char &	f,
		int &	prec

Return the number format for the major scale labels.

Format character and precision have the same meaning as for sprintf().

Parameters:

	f	format character 'e', 'f' or 'g'
	prec	for 'e', 'f': the number of digits after the radix character (point) for 'g': the maximum number of significant digits
