Monitor screen graphic value indicator system

DETAILED DESCRIPTION The present invention overcomes the shortcoming and deficiency of the prior art by providing a graphic value indicating system that uses a moveable rule and various other means to facilitate determining information about points on a display screen.
More specifically, the present invention provides an interface for a graphic screen display including a scale and a plurality of points having values with reference to the scale.
This interface includes at least one operator moveable indicator line that assumes various values throughout its range of movement.
Embodiments of the present invention also include at least one direct value subdisplay presenting the value assumed by the at least one line at any particular instant.
A preferred embodiment of the present invention involves displays of data relating to traffic in a switch.
Accordingly, it is an object of the present invention to provide a means for facilitating extraction of data from a graphic screen display.
Another object of the present invention is to provide a means for quickly and accurately determining the abscissa and/or ordinate values of a point on a Cartesian coordinate system display, which means is particularly useful when the points fall at the top of a bar graph or on a waveform on the display.
Still yet another object of the present invention is to provide a value display system that provides at least two presentations of an indicated value, one presentation involving location of a line against a scale and the other involving a direct value display.
