System and method for displaying three-dimensional object scattergrams of particles are provided. In one embodiment, at least two parameters associated with at least one particle in a biological sample are detected and stored as data. An initial two-dimensional scattergram of the data is created with the two dimensions corresponding to the two parameters, and each data point corresponding to a particle in the biological sample. A data point in the initial two-dimensional scattergram is categorized into a population corresponding to a particle population. A density value of the data point is evaluated. Color data for the data point is calculated based on the evaluated density value and the categorized population. A three-dimensional location is generated based on the location in the initial two-dimensional scattergram and a property of the data point. A geometric shape centered at the generated three-dimensional location is displayed using the calculated color data.
