Hey Steve,
If you look into the Object Manager, there is an object that I have named “Move Me P.Y.” if you move this object up and down you see the change. The Range Manger node will translate any movement from Units in the values you need. Currently it is set to P.Y 0-1000 = 0-100%.
Do you have an excel sheet with the % numbers or any list of % numbers.
I have Googled “graphmaker 3d”, but not certain, as I saw no C4D option. If that search was correct, the question remains, how would you like to get the numbers into C4D, there are options, but so far you need to share more information. Perhaps “Graph Maker v.3” is the one? I’m certain the creator of the plug in is happy to get your feature request.
All the best
Sassi
