Are you sure that contours are the right approach? Much more than 60
different contours is going to be very hard to follow by eye. If you
want to use that many different discrete levels, you might be better off
converting your raw data into discrete integer levels:

discrete_date = FIX( (continuos_data+offset)/bin_size )

and just displaying it directly, rather than trying to draw the lines
seperating the levels. If your array is too small to make decent 'tv'
output, you might want to rebin it (before discretizing it, not after).
