Display method for multi-parameter value monitoring

The invention relates to a display method for multi-parameter value monitoring, and belongs to the field of computers. According to the display method utilizing analysis methods such as principal component analysis, a parameter which can best reflect the state characteristics of a monitored target system is selected from target state parameters as a target state characteristic parameter, a value of the target state characteristic parameter is expressed on a polar axis, the other target state parameters are expressed in a polar radius mode on a polar coordinate plane where the polar axis is located at the same moment, and a three-dimensional data space is formed by the polar coordinate plane and a time axis. In the three-dimensional space, colors and an included angle between the polar radius and the polar axis are used for describing and setting the target state parameters and describing correlations between the target state parameters and the target state characteristic parameter.
