1. A system comprising: a data collector to receive process monitoring data describing a process performed by a process plant, the process monitoring data comprising values for a plurality of process variables; a processor to construct a multivariate model of the process as data is received by the data collector; and a user interface in communication with the processor to present information describing the process, comprising: a first graphical interface to indicate performance of the process plant based on the multivariate model; a second graphical interface to display the contribution of at least one of the plurality of process variables to the multivariate model; and a third graphical interface to display an indication of the deviation of the process from a range expected by the multivariate model.
