public MarginsAppearance Margins {get; set;}
The Margins can be specified on each of the four sides of the Legend box. Developers can employ the Margins property in concert with the SpanPercentage and Location properties to locate a Legend box closer to the corners of the chart.
If values are given for the Margins that exceed the Extent region of the adjacent axis, then the Legend box may not have enough space to render itself and the effects are undefined.
