Display of multiple variable relationships
First Claim
1. A method for graphically displaying at least a first and a second independent physical relationship characterized by a common parameter, wherein the common parameter is defined at N values, the method comprising the steps of:
- superimposing a two-dimensional Cartesian coordinate system on a graphical display, wherein a first axis corresponds to the first relationship and a second axis corresponds to the second relationship;
evaluating the first and second relationships at each of the N common parameter values, wherein corresponding evaluations form a location coordinate at each of the common parameter values and the N location coordinates form a set of display points;
labelling each display point on the display monitor, wherein the common parameter value is indicated for each display point and the first and second independent physical relationships are characterized by the set of display points; and
positioning a first cursor on the display monitor at a selected common parameter value.

Abstract
A method for displaying the joint variation of two or more dependent numerical variables v1 and v2 with respect to a third, independent numerical variable v3. For each of a sequence of numerical values of v3, the coordinate pairs (v1 (v3), v2 (v3)) are displayed on a two-dimensional Cartesian graph of v1 versus v2. A cursor or other indicator is provided on this graph that identifies the numerical value of the third variable v3 at any of the original sequence of such values. The cursor position is continuously interpolated between two consecutive numerical values of v3, corresponding to continuous variation of v3 between these two consecutive numerical values. The joint variation of v1 and v2 is also displayed by provision of two univariate graphs that exhibit v1 and v2 separately as functions of the third variable v3, with a suitable cursor or other movable indicator associated with each graph. The joint variation of v1 and v2 is also displayed as a numerical table of the values of v1, v2 and v3, with a cursor indicating the current choice of value of the variable v3. The graph of v1 (v3) versus v2 (v3) may be provided with an overlay showing normal and/or abnormal ranges of the coordinate pair (v1, v2).

8. A method for displaying at least a first and a second independent physical relationship characterized by a common parameter on a display monitor, wherein the common parameter has N defined values, the method comprising the steps of:
-
superimposing at least two two-dimensional Cartesian coordinate systems on the display monitor such that a first system corresponds to the first relationship and a second system corresponds to the second relationship, wherein the first axis of each system corresponds to the common parameter and a second axis of each system corresponds to the respective relationship; evaluating the first and second physical relationships at each of the common parameter values, wherein a first set of parameter display points is comprised of the corresponding first parameter evaluations and a second set of parameter display points is comprised of the corresponding second parameter evaluations; displaying the first and second sets of parameter display points, wherein the sets are distinguishable from one another; labelling each display point on the display monitor, wherein the labelling of the display points indicates the corresponding parameter value, the first and second independent physical relationships are characterized by the first and second sets of display points; positioning a first cursor on the first system, wherein one of the display points corresponds to a selected parameter value; and positioning a second cursor on the second system at the selected parameter value. - View Dependent Claims (9, 10, 11, 12, 13, 14)
