                                    new go.Binding("text").makeTwoWay()),
                        toolTip: // define a tooltip for each node that displays the color as text
                                GO(go.Adornment, "Auto",
                                        GO(go.Shape, {fill: "#FFFFCC"}),
                                        GO(go.TextBlock, {textAlign: "center",width:"200px"},
                                        new go.Binding("text", "tooltip"))
                                        )  // end of Adornment

please help me.

Auto panels work by sizing themselves automatically based on their inner contents. You’re on the right track, but remove the width specification from your tooltip textblock.


This is incorrect, the value that width takes should be a number, not a string.
