### Remarks

Accepted values range from -100 to 100. A positive value fills the bar from left to right. A negative value fills it from right to left. A value of `0` hides the bar. Setting this property has no effect when the [NodeReference](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graphvisualization/nodereference.md) has no associated [NodeReference.Context](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graphvisualization/nodereference/context.md), such as when it is `default`. Throws ObjectDisposedException when you access this method after you call [Context.Dispose](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graphvisualization/context/dispose.md) on the context.
