What layout are you using?

Set on each Node set Part.locationSpot to be go.Spot.BottomLeft and Part.locationObjectName to be the name of the Panel that holds your “bars”. Then you can set the Part.location for each of your nodes to have the same Y value.

this.diagram.layout=$(go.GridLayout, {
wrappingColumn: Infinity,
alignment: go.GridLayout.Location,
cellSize: new go.Size(1, 1),
spacing: new go.Size(0, 0)
});
