Examination of the homogeneity of pathological lymphoblasts. Representative density dot plots of a homogenous (1) and heterogeneous lymphoblast populations (2–6) on APS dot-plot. Color intensity is proportional to the number of cells. APS dot plot automatically tries to separate populations by looking at all markers together. For a heterogeneous lymphoblast population (2–6), it is clearly visible that there are two dark red areas, so a single population on a bivariate dot plot can be separated into further subpopulations.
