Multivariate graphs representation model based on complex matrix

Aiming at the lack of uniform mathematical model for multivariate graphs representation based on coordinate, a general model based on complex matrix is presented by analyzing and studying the traditional multivariate graphs such as radar chart, scatter plot, trigonometric polynomial graph, parallel coordinate, constellation graph. This model provides a general presentation frame for various multivariate graphs. It is useful for visualization data analyzing, data mining, and studying on a novel method of multivariate graphs.
