Sets or returns properties of the specified element.  If the element number is omitted or is set to 0, the current number of elements in the graph is returned.  If both width and symbol are 0 then the element is hidden.  Note; Element numbers always starts at 1.  The OPTION BASE doesn't affect the element numbering.
