How to align all the node

i m working on graphs i need to align all the node i.e each graph horizontally allignment

i need all 4 to be aligned on the x-axis

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.

i m using grid layout on the diagram and no layout is specified on the nodes

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