The invention discloses a data classification display method, which comprises the steps of collecting equipment data, and constructing a training sample; training a data model based on a binary tree classification method by using the training sample; classifying the to-be-monitored equipment data through the trained data model; according to the classification result, performing classification statistics on the to-be-monitored equipment data; and generating multi-dimensional display data according to the statistical result. The invention further discloses a corresponding system. According to the method, the data model based on the binary tree classification method is constructed. The equipment data is classified through the data model. The multi-dimensional display data is produced according to classification statistics. The process is simple. Meanwhile, multi-dimensional distinguishing display of the data can be achieved.
