The Transform module's Scale operation can operate around any point of an object and the results depend on the origin.
For example, consider a data set with Z values as follows:
Z Min: 90
Z Max: 100
Range: 10
Midpoint: 95
Apply a Z Scale of 0.1 with a central origin and the results are:
Z Min: 94.5
Z Max: 95.5
Range: 1
Midpoint: 95
The Z Min and Z Max are calculated by multiplying the Scale by the range, dividing by 2, and adding or subtracting from the origin.
