A rich phase diagram involving both types of superconductivity is presented as a function of the ratio between the couplings of electrons in the same and different orbitals (${\\rm \\eta= V_{XX}/V_{XY}}$) and electron doping $x$. With the help of a quantity we call orbital-mixing ratio, denoted as $R(\\phi)$, the phase diagram is analyzed using a simple and intuitive picture based on how $R(\\phi)$ varies as electron doping increases.
