Example #1

 def rgb(self, interval, value):
     if qIsNaN(value):
         return 0
     width = interval.width()
     if width <= 0.:
         return 0
     ratio = (value-interval.minValue())/width
     return self.__data.colorStops.rgb(self.__data.mode, ratio)

Example #2

File: color_map.py Project: petebachant/python-qwt

     if qIsNaN(value):
         return 0
     width = interval.width()

         return 0
     ratio = (value - interval.minValue()) / width
     return self.__data.colorStops.rgb(self.__data.mode, ratio)

Example #3

File: color_map.py Project: petebachant/python-qwt

         return int(ratio*255)
     else:
         return int(ratio*255+.5)

Example #4

File: color_map.py Project: petebachant/python-qwt
