I'm not sure if we've ever used it to plot *only* monomials, we always had
some nodal data as well.
Can you call ExodusII_IO::write_timestep() followed by
ExodusII_IO::write_element_data()?
I have wanted to refactor this class for a while... it has had a ton of
stuff tacked onto it over the years without much overall organization.
