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)

| void KDChart::GlobalMeasureScaling::resetFactors | ( | ) | [static] |
Reset factors to the values active before the previous call of setFactors.
This works on a stack, so recursive calls works fine, like: setFactors, setFactors, unserFactors, unsetFactors
