Abstract:
A user interface for monitoring a number of parameters of a system includes an electronic display element and a display driver for controlling the electronic display element so as to display a data graph thereon. The data graph includes a bounded area divided into a plurality of segments, each segment representing one of the parameters; and a number of concentric portions formed in each segment, each concentric portion representing a state or value of the parameter represented by its corresponding segment. The display driver receives data representative of a current state or value of each of the parameters and indicates the current state or value of the parameters by marking the concentric portions that represent the current states or values.
