Addendum to paper: Strong-Coupling Behavior of $\phi^4$-Theories and   Critical Exponents [Phys. Rev. D 57, 2264 (1998)]
  The graphical extrapolation procedure to infinite order of variational perturbation theory in a recent calculation of critical exponents of three-dimensional $\phi^4$-theories at infinite couplings is improved by another way of plotting the results.
