Document generation method and system based on dynamic data

The invention discloses a document generation method based on dynamic data, and the method comprises the steps: constructing the dynamic data of a template document, the dynamic data comprising target chart data corresponding to a plurality of target chart types, target text data corresponding to a text type, and target table data corresponding to a table type; based on the target chart data, obtaining a first calling method from an abstract factory to generate a target basic chart, the target basic chart comprising target theme information, target graphic information and target graphic data set information corresponding to the target chart; obtaining a target second calling method for generating a target chart corresponding to the target chart type from the abstract factory, and generating the target chart based on the target second calling method and the target basic chart; receiving the target chart, the target text data and the target table data in a key-value pair form through the map set; and reading th
