Change control method and system of graph drawing engine

The invention relates to the technical field of graph drawing, and provides a graph drawing engine change control method and system, and the method comprises the steps: constructing a plurality of graph drawing engines based on a historical graph drawing log of a graph drawing processing end; according to the method, matched graph drawing engines can be provided for different graph drawing requirements in the process that a graph drawing processing end executes a graph drawing task, a proper storage interval is configured for each graph drawing engine, and the data storage requirement in the graph drawing process is guaranteed; according to the method, graph drawing task data is divided into a plurality of task sub-data, the task sub-data are loaded to a corresponding graph drawing engine, optimal graph drawing is provided for each piece of task sub-data, and the quality and efficiency of graph drawing operation corresponding to each piece of task sub-data are improved; in addition, the graph drawing engines
