Method for automatically generating analysis graph and loading document in java background

Abstract

The invention discloses a method for automatically generating an analysis graph and loading a document in a java background, and relates to the technical field of graph processing. The method comprises the following steps of establishing a graph template according to the graph type; defining a required data structure and parameter configuration in the graphic template; processing the data into a data structure required by the corresponding graphic template according to the graphic type; reading the graphic template in the form of a data stream according to the graphic type, loading the processed data and configuration parameters into the graphic template for graphic drawing, outputting the generated graph in the form of a file output stream, returning an output address, and generating a report file for reading after the output address is obtained. By utilizing the method provided by the invention, a convenient method capable of generating a high-quality customizable analysis graph is provided for developers, and complicated data can be subjected to graph drawing and display through the graph template, so that information such as a relationship or trend between the analysis data canbe observed conveniently, and a basis is provided for optimizing an industrial structure and predicting future development.

Description

technical field [0001] The invention discloses a method for automatically generating an analysis graph and loading a document in a Java background, and relates to the technical field of graphic processing. Background technique [0002] With the advent of the information age, all walks of life have produced a huge amount of relevant data. It is very necessary to use various data analysis techniques to carry out data mining analysis on the huge amount of relevant data, and then display it intuitively. In terms of data display, line charts, histograms, pie charts, custom special graphics, etc. are commonly used. The front page displays relatively mature components such as echarts, highcharts, etc., but in many projects, it is often necessary to directly generate and analyze the analysis data in the java background Graphs are used to generate reports, but these components are not directly available behind the scenes. Although there are tools such as jfreechart for directly gene...

In terms of data display, line charts, histograms, pie charts, custom special graphics, etc. are commonly used. The front page displays relatively mature components such as echarts, highcharts, etc., but in many projects, it is often necessary to directly generate and analyze the analysis data in the java background Graphics are used to generate reports, but these components cannot be used directly in the background

Although there are tools such as jfreechart to directly generate analysis diagrams in the java background, the quality of the generated images is poor, and there are few configurable items, which is difficult to meet customer needs
