STRETCH_CURVE
Basic Overview
Description  Stretches the curve(s) defined in the 'CurvesNode' over the X axis by a factor defined in 'StretchNode'. You can specify the X coordinate at where the stretching begins with the 'StartNode' parameter. The stretching begins at 0 by default. The X coordinates are represented by the Sequence level in 'CurvesNode'. The Y coordinates are represented by the values of 'CurvesNode'. 
Signature  STRETCH_CURVE(CurvesNode, StretchNode [, StartNode]) 
Parameters 

Example
Input CurvesNode =

Input StartNode =
Project  Value 

B  2 
The project A will default to 0.
