Abstract：The vector translation method is an analysis method of combining Lorenz scatter plot and difference scatter plot, which is derived from fully understanding their mapping principles and inherent relationship between the two kinds of plots. It embodies the complementary relationship between Lorenz scatter plot and difference scatter plot.The vector translation method is not only suitable for the comprehensive analysis of twodimensional Lorenz scatter plot and twodimensional difference scatter plot, but also for the comprehensive analysis of threedimensional Lorenz scatter plot and threedimensional difference scatter plot. The directed critically connected graph is a closed vector ring, which indicates that difference scatter plot satisfies the law of conservation of vectors. Correctly labeling the directed critically connected graph is a prerequisite for vector translation. The scatter plots of intractable case have complex typing and hidden regularity. The vector translation method by using a combination of two kinds of plots could fully reveal the inherent law of ECG big data, especially the characteristic point sets of difference scatter plot do not overlap with each other, which facilitates analysis operations such as editing and graph selection, and makes it possible to analyze difficult and complex ambulatory electrocardiography quickly and accurately.
