QwtLinearScaleEngine::QwtLinearScaleEngine(uintbase=10)
       Constructor

       Parameters:base Base of the scale engine

       A scale engine for linear scales.
                                                       ight
       The step size will fit into the pattern $t 1,2,5

QwtIntervalQwtLinearScaleEngine::align(constQwtInterval&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

   voidQwtLinearScaleEngine::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)

       Implements QwtScaleEngine.

       Reimplemented in QwtDateScaleEngine.

   QList<double>QwtLinearScaleEngine::buildMajorTicks(constQwtInterval&interval,doublestepSize)const[protected]
       Calculate major ticks for an interval.

       Parameters:interval Interval
           stepSize Step size

       Returns:
           Calculated ticks

   voidQwtLinearScaleEngine::buildMinorTicks(constQList<double>&majorTicks,intmaxMinorSteps,doublestepSize,QList<double>&minorTicks,QList<double>&mediumTicks)const[protected]
       Calculate minor/medium ticks for major ticks.

       Parameters:majorTicks Major ticks
           maxMinorSteps Maximum number of minor steps
           stepSize Step size
           minorTicks Array to be filled with the calculated minor ticks
           mediumTicks Array to be filled with the calculated medium ticks

   voidQwtLinearScaleEngine::buildTicks(constQwtInterval&interval,doublestepSize,intmaxMinorSteps,QList<double>ticks[QwtScaleDiv::NTickTypes])const[protected]
       Calculate ticks for an interval.

       Parameters:interval Interval
           stepSize Step size
           maxMinorSteps Maximum number of minor steps
           ticks Arrays to be filled with the calculated ticks

       Seealso:buildMajorTicks(), buildMinorTicksQwtScaleDivQwtLinearScaleEngine::divideScale(doublex1,doublex2,intmaxMajorSteps,intmaxMinorSteps,doublestepSize=0.0)const[virtual]
       Calculate a scale division for an interval.

       Parameters:x1 First interval limit
