The Y-Axis can be shifted vertically using labelConversion: and a minor translation of the value, as in:
b := RTGrapher new.
ds := RTStackedDataSet new.
ds barShape color: Color red.
ds points: #(5 1 20 8).
ds y: [ :v | v - 10 ].
b add: ds.
b axisX noLabel; noTick. b axisY noDecimal.
b axisY labelConversion: [ :v | v + 10 ].
b build.
