Rescale functions

Rescale functions are used to scale data items to new distributions.

• rescale - rescales the distribution of an attribute, between a minimum and a maximum value
• scalesum - disaggregates the values of a parameter according to the distribution of a proxy attribute
• normalize - scales the attribute to a normal distribution
• interpolate_linear - interpolates the values of an attribute a towards a new domain unit

• ramp - ramps values, starting with a startvalue and ending with an endvalue
• ramp_rgb - ramps rgb values, starting with a startvalue and ending with an endvalue
• ramp_open - ramps values, starting with a startvalue up to an endvalue
• ramp_open_rgb - ramps rgb values, starting with a startvalue up to an endvalue
