  We perform theoretical calculations to obtain a distribution of local d-wave
superconducting gaps $\Delta_0({r})$ for a high temperature superconducting
(HTSC) series in a disordered superconductor with an average doping level
$<\rho>$. To reproduce the inhomogeneous medium a nonmagnetic random potential
$V^{imp}$, within a Bogoliubov-de Gennes (BdG) formalism, is considered. First
the phase diagram $\Delta_0 x <\rho>$ for the LSCO HTSC series, with V^{imp}=0,
is obtained. Then, we perform calculations considering a fixed value of the
disorder strength $V^{imp}$ and obtain a distribution of local superconducting
gaps $\Delta_0({r})$, and local density of charge carriers $\rho({r})$. It is
shown that the underdoped compounds are more inhomogeneous than the overdoped
ones, which is in accordance with experimental findings. Also, the spatial
variation of $\Delta_0({r})$ indicates that as <\rho> increases, the system
becomes more homogeneous.
