We show that extensive statistical mechanics information can be obtained by the calculation of local densities such as local magnetizations and neighbor correlations, made possible by renormalization-group theory. This is illustrated with quenched random-bond, random-field, and spin-glass systems, in two and three dimensions. The different ordering behaviors thus become vividly and quantitatively apparent. {copyright} {ital 1997} {ital The American Physical Society}
