Graph mapper to extend curves in uneven way

I'm not sure if you can extend curves with the graph mapper, but the way its intended to work is that a series of numbers within the range of the graph are supplied as the input. The graph mapper evaluates where the y values of the supplied X values are, then outputs those y values...

Hi Arthur,

A Graph mapper is just a froody way to display a function (remember high school math classes? F(x) = ax+b; f(x) = ax²+bx+x; f(x) = sin(x+t) etc. etc.)

You plug in a number and it gets post-processed by the graph equation. If you pick a graph type that works along the entire number range (such as sine, linear, parabola, perlin) the graph will extend beyond the edges of the viewer. If however you pick a type that is only valid within the visible range, then the numbers beyond that range will be treated differently.

Thanks David.
Would there be a way to add one or several control points to the Bezier Graph Mapper? That would be great in order to have more control over it!
