  • Method and apparatus for comparing a sample with a reference using a spider diagram
    Patent number: 5731998
    Abstract: A spider-diagram type of display is used to compare measured parameter values of a sample of interest with reference values for the parameters. The reference values are derived from measurements on a specified reference set of samples selected from a group of samples for which parameter measurements are available. The derived reference values are represented in the spider diagram by predetermined reference values that together delimit, for example, a circle. The measured parameter values of the sample of interest are scaled before display according to a respective scaling factor determined for each parameter by the ratio of the predetermined and derived reference values for the parameter concerned.
