   QwtCompassScaleDraw::QwtCompassScaleDraw(constQMap<double,QString>&map)[explicit]
       Constructor.

       Parameters:map Value to label map

       A special scale draw made for QwtCompass.

       QwtCompassScaleDraw maps values to strings using a special map, that can be modified by the application

       The default map consists of the labels N, NE, E, SE, S, SW, W, NW.

       Seealso:QwtCompass

QwtTextQwtCompassScaleDraw::label(doublevalue)const[virtual]
       Map a value to a corresponding label

       Parameters:value Value that will be mapped

       label() looks in the labelMap() for a corresponding label for value or returns an null text.

       Returns:
           Label

       Reimplemented from QwtAbstractScaleDraw.

   QMap<double,QString>QwtCompassScaleDraw::labelMap()constReturns:
           map, mapping values to labels

       Seealso:setLabelMap()voidQwtCompassScaleDraw::setLabelMap(constQMap<double,QString>&map)
       Set a map, mapping values to labels.

       Parameters:map Value to label map

       The values of the major ticks are found by looking into this map. The default map consists of the labels
       N, NE, E, SE, S, SW, W, NW.

       Warning:
           The map will have no effect for values that are no major tick values. Major ticks can be changed by
           QwtScaleDraw::setScale
