Problem
When an attribute is not appearing in the diagram model (nodeArray), a different property should be selected
Ansatz – Approach
The third paramater of the Binding Constructor can be used to declare a function that handles the nodeData.
Lösung – Solution
// the node template describes how each Node should be constructed diagram.nodeTemplate = $(go.Node, "Auto", // the Shape automatically fits around the TextBlock new go.Binding("location", "loc", go.Point.parse), $(go.Shape, "RoundedRectangle", // use this kind of figure for the Shape // bind Shape.fill to Node.data.color new go.Binding("fill", "color")), $(go.TextBlock, { margin: 5, width: 100 }, // some room around the text // bind TextBlock.text to Node.data.key new go.Binding("text", "", function(data) { return (data.text) ? data.text : data.key; } )) );
