In reply to djmandela:

This is another implementation, where bin is created for each values per index basis.

module array_covergroup_test();

   bit [7:0] data[127:0] ;
   bit [7:0] values [$] = {8'd1,8'd2,8'd4};

   covergroup array_cg (int index);
       option.per_instance = 1;
       coverpoint data[index] {
           bins value[] =  {8'd1,8'd2,8'd4}; //{values};
	}
   endgroup

   array_cg cg[128];

   initial begin
      foreach(cg[i])begin
        cg[i] = new(i);
      end

      repeat(100)begin
	 std::randomize(data);
	 foreach(cg[i])begin
	    cg[i].sample();
	 end
      end 
   end 
   
endmodule // array_covergroup_test
