Spacing between specific nodes

How do I increase/decrease the space between specific two nodes in a LayeredDigraphLayout ?
I want to decrease the space between nodes 4 & 6 only.

How is your layout defined?

Hey walter,
This is the code for the layout

     layout: $(go.LayeredDigraphLayout, {
          direction: 90,
          packOption: go.LayeredDigraphLayout.PackStraighten,

Did you manually move node 6 in your screenshot? Hmm, and node 7 too, it seems.

LayeredDigraphLayout intentionally arranges nodes into layers, so the vertical centers of the nodes in a layer will be in a horizontal line.

You could override commitLayout to shift upwards the LayoutVertex corresponding to node 6, and then call the super method.
