      Plots a histogram consisting of
      nbini'th bin is placed in
      x[i]y[i]x[i]x[i]i'th bin. If
      opt=PL_BIN_CENTREDxplhist
      for drawing histograms from unbinned data.
    
nbin
	  (PLINT
	    Number of bins (i.e., number of values in
	    xy
x
	  (PLFLT_VECTORA vector containing values associated with bins. These must form a strictly increasing sequence.
y
	  (PLFLT_VECTOR
	    A vector containing a number which is proportional
	    to the number of points in each bin.  This is a
	    PLFLT (instead of PLINT) vector
	    so as to allow histograms of probabilities, etc.
	  
opt
	  (PLINTIs a combination of several flags:
		  opt=PL_BIN_DEFAULTx
		  opt=PL_BIN_CENTRED|...xx
		  opt=PL_BIN_NOEXPAND|...
		  opt=PL_BIN_NOEMPTY|...
