Multi-source data visual analysis and display method and system

The invention discloses a multi-source data visual analysis and display method and system. The multi-source data visual analysis and display method comprises the steps of receiving all data information, cleaning data, deleting abnormal data, and obtaining a data sample set; according to the type of the data sample, selecting the size of a clustering number K value; distributing the data samples inthe data sample set to the nearest neighbor cluster according to the minimum distance principle; recalculating the centers of the K clusters according to the nearest clustering result, and taking thecenters as new clustering centers; judging whether convergence occurs or not, namely judging whether the clustering center does not change any more, and if not, repeating until convergence to obtainan optimal clustering result; according to the optimal clustering result, marking corresponding labels on the data samples and enabling the labels to correspond to the display templates in a one-to-one mode, and conducting disp
