  Two FORTRAN programs are presented which plot the Hertzsprung-Russell diagram
and the temporal evolution of such stellar quantities as: central and
photospheric isotopic abundances, central densities and temperatures,
luminosities,effective temperatures and photospheric radii for a wide range of
stellar masses. The programs, which are modifications and extensions of some
modules of the TYCHO 6.0 stellar evolution package, are accompanied by various
control input files as well as by a library of data. The data library is
actually one of the output files generated by TYCHO 7.0 (a modified version of
TYCHO 6.0), while the plots themselves are generated by the PGPLOT Graphics
Subroutine Library which is also publicly available and well cited.
