Abstract: A device and method for displaying variable data comprises: logic for displaying a gauge that comprises a closed two-dimensional shape. The two-dimensional shape comprises a linear pointer inside the shape, the location of the pointer being determined as a function of a change in an item of data during a predetermined time interval. A device and method for displaying variable data comprises: logic for displaying an annular graph representing changes in a quantifiable item of data during a predetermined time interval, wherein the annular graph is positioned around a clock face. A computer program product comprises instructions for: displaying a graphical representation of variable data comprising displaying a gauge; and also for: displaying an annular graph representing changes in a quantifiable item of data during a predetermined time interval, wherein the annular graph is positioned around a clock face.
