Abstract
The twice scaled waveform display apparatus combines a twice scaled factor indication with the autoscaled waveform display so that an input data quality indication is produced based on factors such as signal strength, wherein the twice scaled factor is used to modulate the size of the display that is presented to the user. Thus, the generated waveform occupies a predetermined portion of the display when the signal strength and/or other input data qualities are at an acceptable level. The size of the waveform presented to the user on the display is reduced in magnitude when there is a degradation in the input signal magnitude or other quality factors.

Apparatus for concurrently displaying a plurality of information on a single display comprising:
- means for storing a plurality of data values, said plurality of data values being indicative of a sequence of measurements of a monitored variable;
- means for autoscaling said plurality of data values to produce a display on a display device indicative of said plurality of data values;
- means for determining a characteristic of said measurements;
- means for computing a twice scaled factor based on said determined characteristic;
- and
- means for modulating a magnitude of said display as a function of said computed twice scaled factor.
