Abstract: A method for displaying an operating parameter for a mobile platform. A plurality of different graphs can be digitized to place them in electronic form. Each graph represents a different operational or environmental characteristic relating to operation of the mobile platform, and each is further related to a common parameter. A first one of the digitized graphs is selected by a user. A user positionable marker is displayed on the first digitized graph at a specific, user selected location on the first digitized graph. Next a second one of the digitized graphs is selected. The second one of the digitized graphs is then overlayed over at least a portion of the first digitized graph, with the marker remaining visible and superimposed on the second digitized graph, and without having moved relative to the first digitized graph. The second digitized graph is then aligned relative to the first digitized graph. The marker is then used to assist in reading information from the second digitized graph.
