We have provided a gr_plot_ofdm.py tool to visualize the results  
(you'll find it in the gnuradio-examples/python/ofdm directory). With 
the different modulations per subcarrier, the display is going to look a 
bit odd, but it should show you that at least something is going on. You 
could modify this code to distinguish the constellation per subcarrier 
somehow.
