Hadron multiplicities in semi-inclusive deep-inelastic scattering were measured on neon, krypton and xenon targets relative to deuterium at an electron-beam energy of 27.6 GeV at HERMES. These ratios were determined as a function of the virtual-photon energy nu, its virtuality Q^2, the fractional hadron energy z and the transverse hadron momentum p_t with respect to the virtual-photon direction. Dependences were analysed separately for positively and negatively charged pions and kaons as well as protons and antiprotons in a two-dimensional representation. These results will help to constrain mechanisms and models of hadronization much more decisively than by the use of integrated results as traditionally done. A few features particular to the two-dimensional representation will be highlighted in this contribution. For example, at lower values of nu positive kaons do not show the typical rise of the multiplicity ratio with nu when z>0.4. In addition, protons were found to behave very differently from the other hadrons.
