Public Member Functions virtual void autoScale (int maxSteps, double &x1, double &x2, double &stepSize) const virtual QwtScaleDiv divideScale (double x1, double x2, int numMajorSteps, int numMinorSteps, double stepSize=0.0) const virtual QwtScaleTransformation * transformation () const Protected Member Functions QwtDoubleInterval align (const QwtDoubleInterval &, double stepSize) const Additional Inherited Members Detailed Description A scale engine for linear scales. The step size will fit into the pattern $re n is an integer. Member Function Documentation QwtDoubleInterval QwtLinearScaleEngine::align (const QwtDoubleInterval &interval, doublestepSize) const [protected] Align an interval to a step size. The limits of an interval are aligned that both are integer multiples of the step size. Parameters: interval Interval stepSize Step size Returns: Aligned interval void QwtLinearScaleEngine::autoScale (intmaxNumSteps, double &x1, double &x2, double &stepSize) const [virtual] Align and divide an interval Parameters: maxNumSteps Max. number of steps x1 First limit of the interval (In/Out) x2 Second limit of the interval (In/Out) stepSize Step size (Out) See also: setAttribute() Implements QwtScaleEngine. QwtScaleDiv QwtLinearScaleEngine::divideScale (doublex1, doublex2, intmaxMajSteps, intmaxMinSteps, doublestepSize = 0.0) const [virtual] Calculate a scale division. Parameters: x1 First interval limit x2 Second interval limit maxMajSteps Maximum for the number of major steps maxMinSteps Maximum number of minor steps stepSize Step size. If stepSize == 0, the scaleEngine calculates one. See also: QwtScaleEngine::stepSize(), QwtScaleEngine::subDivide() Implements QwtScaleEngine. QwtScaleTransformation * QwtLinearScaleEngine::transformation () const [virtual] Return a transformation, for linear scales Implements QwtScaleEngine.
