 PLOTA plots all kind of data types
 PLOTA(Labels,'ELPOS')
       displays 2-D location of EEG channels described by Labels
 PLOTA(Labels,'ELPOS3')
       displays 3-D location of EEG channels described by Labels
 PLOTA(X [,Mode])
 if X.TYPE=='EVENT' and X.EVENT
 
 X.datatype determines type of data
