1. A system for graphically representing in a space data representing at least one portfolio, comprising: a memory arrangement storing a Multi-Criteria Financial Optimization (“MCFO”); and a processor solving the MCFO based on at least one input condition to generate data corresponding to a set of portfolios, the processor selecting vertex points corresponding to a set of components of the portfolios, the processor defining coordinates of the vertices on a chart, the processor defining a projection vector-function using coordinates of the vertices and selecting a subset of the portfolios on the chart, the processor computing coordinates for the portfolios in the subset using the projection vector-function and a weighting corresponding to the portfolios, the processor plotting points corresponding to the portfolios in the subset on the chart using the computed coordinates.
