QwtAbstractScale is used to provide classes with a QwtScaleDraw, and a QwtScaleDiv. The QwtScaleDiv might be set explicitely or calculated by a QwtScaleEngine.

Constructor Creates a default QwtScaleDraw and a QwtLinearScaleEngine. Autoscaling is enabled, and the stepSize is initialized by 0.0. Definition at line 53 of file qwt_abstract_scale.cpp. References rescale(). |

Set the maximum number of major tick intervals. The scale's major ticks are calculated automatically such that the number of major intervals does not exceed ticks. The default value is 5.

Set the maximum number of minor tick intervals. The scale's minor ticks are calculated automatically such that the number of minor intervals does not exceed ticks. The default value is 3.
