Detailed Description

Auxiliary class used by the KDChart::Measure and KDChart::Chart class.

Normally there should be no need to call any of these methods yourself.

They are used by KDChart::Chart::paint( QPainter*, const QRect& ) to adjust all of the relative Measures according to the target rectangle's size.

Default factors are (1.0, 1.0)
