ABSTRACT:
Accurate, unambiguous, and space-efficient electronic display techniques are provided for presenting the operator with an indicator whose graphical configuration varies in accordance with whether the relevant control value is within a predetermined tolerance range of a set-point value. More particularly, a control value indicator includes a scale having an axis associated with the control value, a set-point marker placed at a first position along the scale for indicating the set-point value, and a pointer having a second position along the scale for indicating the control value. The pointer and/or the set-point marker exhibit a first graphical configuration corresponding to the case where the control value is not within the predetermined tolerance of the set-point value, and a second graphical configuration corresponding to the case where the control value is within the predetermined tolerance of the set-point value.
