  direction              either a scalar integer (all labels have the same position 
                         
                         relative to their corresponding datapoint) 
                         
                         or a (n x 1) vector of integers (each label gets the position 
                         
                         associated with the integer in the corresponding row), 
                         
                         
                         
                         -1 is for no label at all, 
                         
                         0 is for centered label, 
                         
                         3 is for a label to the right of the corresponding datapoint, 
                         
                         6 is for a label below the corresponding datapoint, 
                         
                         9 is for a label to the left of the corresponding datapoint, 
                         
                         12 is for a label above the corresponding datapoint, 
                         
                         This parameter is not implemented under windows version. ; 
                         
                         
                         
  size                   either a scalar integer (all labels have the same size) 
                         
                         or a (n x 1) vector of integers (each label gets the size 
                         
                         associated with the integer in the corresponding row); 
                         
                         XploRe4 supports the font sizes: 12 ... 16
