\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 upperLimit() might be smaller than the lowerLimit() |
|
to indicate inverted scales. |
|
|
|
Scale divisions can be calculated from a QwtScaleEngine. |
|
|
|

|
QwtAbstractSlider::setScaleDiv() |
