Paneling tools + graph mapper

Hello everyone,

I am trying to create a pattern which varies both in width and in height. I have managed to make the surface division in X to depend on a graph mapper. I have then interpolated a curve using the surface grid points and would like the center point of this curve to be controlled the same manner, preferably by a separate graph mapper - in the end, one graph mapper would give me the width of the component and another the height of the curve center point.

I may have missed a simpler manner to do this (perhaps scaling non-uniformly with paneling tools)?

Many thanks,

Ricardo
