According to the defects of quantity evaluation of corporate customers' experience,this paper proposes using radar chart and cloud model to evaluate users' attitudes based on multi-index attributes.This method is built on multivariate graphical presentation used in quality management and mathematical geology.Radar charts are employed to demonstrate indexes all at a time.This paper innovatively puts forward radar coverage coefficient and radar map to pull off a comprehensive quantity evaluation with the aid of cloud model theory.Radar image illustrates the users' attitudes in terms of radar span which conforms to the quantity and quality evaluation method.
