The value of this property is expressed as a fractional value between 0 and 1 which represents the ratio of the offset to the width of the chart element.
For example, a value of 0 positions the text area as close as possible to the edge of the chart element; a value of 1 positions it as close as possible to the opposite edge. All values in between 0 and 1 represent a scalar which, when applied to the width of the entire chart element, yields the offset.
