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)

resetFactors()

void KDChart::GlobalMeasureScaling::resetFactors ( )

setFactors()

void KDChart::GlobalMeasureScaling::setFactors ( qreal  factorX, qreal  factorY  )

static

Set new factors to be used by all Measure objects from now on. Previous values will be saved on a stack internally.
