\brief A class representing a scale division
|
||
|
|
|
||
|
|
A Qwt scale is defined by its boundaries and 3 list
|
||
|
|
for the positions of the major, medium and minor ticks.
|
||
|
|
|
||
|
|
The upperBound() might be smaller than the lowerBound()
|
||
|
|
to indicate inverted scales.
|
||
|
|
|
||
|
|
Scale divisions can be calculated from a QwtScaleEngine.
|
||
|
|
|
||
|
|
\sa QwtScaleEngine::divideScale(), QwtPlot::setAxisScaleDiv(),
|
||
|
|
QwtAbstractSlider::setScaleDiv()
