I am just guessing what you mean by "leave the graph where it is" but note that you need to remove the zero values from both the wavelength and flux vectors. So, applying the idlastro procedure remove.pro to your wavelength, w, and flux, f, vectors:
g = where(f eq 0,Ng) ;Find locations of zero values in flux vector
if Ng gt 0 then remove,g,w,f ;Remove these locations from both wavelength & flux vectors
