Patent ID: 8713423

Claim:
A method, comprising: receiving, via a user input device, a request for differential data; detecting a graphical user interface (GUI) focus event that indicates a GUI cursor has been moved over a first data element of a plurality of data elements relative to which to apply a user-defined differential data formula that specifies a differential calculation selected based upon a data type of the plurality of data elements; calculating, in response to detecting the GUI focus event that indicates the GUI cursor has been moved over the first data element, via the user-defined differential data formula using each data value associated with each data element of the plurality of data elements as differential input data, a first differential data value for each of the plurality of data elements relative to a data value of the first data element; and displaying the first differential data value for each of the plurality of data elements at an original display location of each of the plurality of data elements on a display in response to the received request.
