### Remarks

Accepted values range from -100f to 100f. 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. This field is an override applied on top of [IState.FillAmount](/engine/6000.7/script-reference/unity/graphtoolkit/editor/istate/fillamount.md). The default value is `0`, but it has no effect. Call the setter to start applying the override. Call [StateReference.ClearCustomization](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/statereference/clearcustomization.md) to remove the override. Setting this property has no effect when the [StateReference](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/statereference.md) has no associated [StateReference.Context](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/statereference/context.md), such as when it is `default`. Throws ObjectDisposedException when you access this method after you call [Context.Dispose](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/context/dispose.md) on the context.
