def derive(tvar,newname=None, new_tvar=None):

    Takes the derivative of the tplot variable.

    Parameters
    ----------
        tvar : str
            Name of tplot variable.
        new_tvar : str (Deprecated)
            Name of new tplot variable.  If not set, then the data in tvar is replaced.
        newname : str
            Name of new tplot variable.  If not set, then the data in tvar is replaced.

    Returns
