DIAGNOSTIC VISUAL TOOLS AND METHODS FOR GRAPHICAL COMPARISON OF DATA POINT AND HISTORICAL DATA DENSITY

摘要

Methods, computer program products, and systems adapted to aid in data analysis by graphically displaying current situation on the background of historical data density, Historical data density is represented by one or more contour plots. An indicator of how a current data point compares to the historical data may be placed on one or more of the data density graphs. In some examples, data falling outside a threshold contour of historical data density may represent a new or an abnormal situation, and such data and/or a contour plot having such data may be highlighted in a graphical display.
