public Boolean DrawBehind {get; set;}
Remarks
The Legend DrawBehind property specifies whether or not the Legend is drawn behind
other Chart elements. By default, its value is false, although for backward compatibility
it is set to true when Legend.CustomPosition is set to true.
Example:
tChart1.Legend.DrawBehind = false;
