Abstract: Graphs for displaying data are generated by acquiring signals using a signal acquisition device. The signals are processed to obtain a first series of data and a second series of data comprising independent and dependent variables. A search is performed of the dependent variables of the first series of data and the second series of data and the minimum dependent variable value and maximum dependent variable value are determined. The scale of a second axis of a first graph and of a second graph are determined such that the scales of the second axes of the first and second graphs have the same units and minimum and maximum second axis scale values; and the minimum second axis scale value is no larger than the minimum dependent variable value and the maximum second axis scale value is no smaller than the maximum dependent variable value so that the entire range of the dependent variables of the first series is displayed at or between the minimum and maximum second axis scale values.

Abstract: A measurement system comprises a signal acquisition device for acquiring signals. A processor processes the signals to obtain a first series of data and a second series of data. A display device receives the first series of data and the second series of data. A first graph on the display device has a first graph first axis and a first graph second axis with the first series of data displayed thereon. A second graph on the display device has a second graph first axis and a second graph second axis with the second series of data displayed thereon. The first graph first axis has the same units and minimum and maximum first axis scale values as the second graph second axis. Also, the first graph second axis is recalibrated from having different minimum and maximum second axis scale values as the second graph second axis to having the same units and minimum and maximum second axis scale values as the second graph second axis.
