Answer 1

Here's how I do it.

from Spotfire.Dxp.Application.Visuals import VisualContent

#"visual" is the name of the parameter found in the "Script Parameter" dialog below the editor which points to the visualization I want to change.
vc = visual.As[VisualContent]()
exp="["+Document.Properties["DocPropertyNameHere"]+"]"
vc.YAxis.Expression =exp
