Changing different number slider at the same time but with different data

(Grasshopper)

Hello everybody,

I’m trying to create a modelisation of a tree on Grasshopper that will be modify depending on values that have an impact on the roots, the leaves and the trunk.
I succeeded to do that but now I want to create a unique slider that gathers all the precious one. But the difficulty is that I don’t want to be the same value for each and not to evolve in a proportional way.
This cursor has to show how all the parts of tree evolve depending on the humidity of the ground (that would be the new cursor).

Example:

humidity of the ground: 50%

Roots:
Section: 2 inch (0,05 m)
high: 157 inch (4 m)

Leaf:
Thickness: 0.2 inch (0,005 m)
Length: 4 inch (0,1 m)

Trunk:
Diameter: 12 inch (0,3 m)
High: 315 inch (8 m)

This is a very general idea, not a specific solution to your “modelisation”. As you move the slider in the blue group (0 to 1), three values change according to multiple Graph Mapper components and the ‘Min/Max’ domain bounds wired to each ReMap.

P.S. Oops, re-posted image due to copy/paste wiring error.

Later - updated image again for cosmetic improvement.

Thank you very much for your quick reply. I’m trying that solution

It works thank you ! Just a little question: Does the curve shape from the graph mapper influence the result or only if it’s a decreasing or increasing curve ?

Yes, unless the Graph Mapper is a straight line (the default). Might be easier to see this way:
