## Abstract

A system, method, and medium for virtually real time monitoring of machine performance are described. An optimal set-point for a data source is determined. The data source corresponds to operation of a machine. Virtually real time data is received from the data source corresponding to current operation of the machine. A deviation between the virtually real time data and the optimal set-point for the data source is computed. An intensity map is rendered representing the computed deviation according to a predefined visual gradient.
