Thanks Max,

Remapper node is a brilliant start.

>> In fact it's really hard. :)
Please know that I am eternally grateful.


I'm sure you know full well what needs to be done for it to function correctly,
but by way of helping to clarify things I prepared the attached NE file.

At the moment the node only works within the range of input array.
So it first needs to remap the array to within new range.

The math to do this is very simple, as shown.
Ideally this functionality would be incorporated into the node.

In the event that no new range is input into the node,
the output array would remain within existing range.

I hope this accords with your intentions.

Have a great weekend
& thanks again

P.S. I know the remapping does not correlate perfectly with the curve,
(for instance a diagonal straight line does not result with no change to
array as expected), nevertheless it is still workable.
Although perfecting this is desirable, it is less urgent IMHO
than the remapping to new range as outlined above.
