.PP 
\fBQwtSaturationValueColorMap\fP varies the saturation and/or value for a given hue in the HSV color model\&. 

Value and saturation are in the range of 0 to 255 while hue is in the range of 0 to 259\&.

.PP
Constructor\&. The value interval is initialized by 0 to 255, saturation by 255 to 255\&. Hue to 0 and alpha to 255\&.
.PP
So the default setting interpolates the value coordinate only\&.
