QwtLinearColorMap::QwtLinearColorMap(QwtColorMap::Formatformat=QwtColorMap::RGB)
       Build a color map with two stops at 0.0 and 1.0. The color at 0.0 is Qt::blue, at 1.0 it is Qt::yellow.

       Parameters:format Preferred format of the color map

   QwtLinearColorMap::QwtLinearColorMap(constQColor&color1,constQColor&color2,QwtColorMap::Formatformat=QwtColorMap::RGB)
       Build a color map with two stops at 0.0 and 1.0.

       Parameters:color1 Color used for the minimum value of the value interval
           color2 Color used for the maximum value of the value interval
           format Preferred format for the color map

QwtLinearColorMap builds a color map from color stops.

       A color stop is a color at a specific position. The valid range for the positions is [0.0, 1.0]. When
       mapping a value into a color it is translated into this interval according to mode().

enumQwtLinearColorMap::Mode
       Mode of color map

       Seealso:setMode(), mode()EnumeratorFixedColors
              Return the color from the next lower color stop.

       ScaledColors
              Interpolating the colors of the adjacent stops.

voidQwtLinearColorMap::addColorStop(doublevalue,constQColor&color)
       Add a color stop

       The value has to be in the range [0.0, 1.0]. F.e. a stop at position 17.0 for a range [10.0,20.0] must be
       passed as: (17.0 - 10.0) / (20.0 - 10.0)

       Parameters:value Value between [0.0, 1.0]
           color Color stop

   QColorQwtLinearColorMap::color1()constReturns:
           the first color of the color range

           the second color of the color range

       Seealso:setColorInterval()unsignedcharQwtLinearColorMap::colorIndex(constQwtInterval&interval,doublevalue)const[virtual]
       Map a value of a given interval into a color index.

       Parameters:interval Range for all values
           value Value to map into a color index

       Returns:
           Index, between 0 and 255

       Implements QwtColorMap.

   QVector<double>QwtLinearColorMap::colorStops()constReturns:
           Positions of color stops in increasing order

   QwtLinearColorMap::ModeQwtLinearColorMap::mode()constReturns:
           Mode of the color map

       Seealso:setMode()QRgbQwtLinearColorMap::rgb(constQwtInterval&interval,doublevalue)const[virtual]
       Map a value of a given interval into a RGB value

       Parameters:interval Range for all values
           value Value to map into a RGB value

       Returns:
           RGB value for value

       Implements QwtColorMap.

   voidQwtLinearColorMap::setColorInterval(constQColor&color1,constQColor&color2)
       Set the color range

       Add stops at 0.0 and 1.0.

       Parameters:color1 Color used for the minimum value of the value interval
           color2 Color used for the maximum value of the value interval

       Seealso:color1(), color2()voidQwtLinearColorMap::setMode(Modemode)
       Set the mode of the color map. FixedColors means the color is calculated from the next lower color  stop.
       ScaledColors means the color is calculated by interpolating the colors of the adjacent stops.
