Method and system for visualizing data

The embodiment of the invention discloses a method for visualizing data. The method comprises the following steps: meshing data through the method of superposition of trend surface and residual error; applying corresponding visualization technologies to the meshed data; removing repetitive data and leaving essential data through logic simplification, texture simplification and code compression; analyzing data format, assembling logic relation and generating visual data; and displaying the visual data. The embodiment of the invention further discloses a system for visualizing the data. According to the embodiment of the invention, the visualization technologies are combined so as to be suitable for different data fields very well; and on the basis that the basic visualization technology is combined with the visualization technology based on feature analysis, the visualization quality can be further improved, and the calculated amount is not large.
