Abstract
Disclosed are methods, apparatuses, etc. for providing a visual expression of the performance of one or more blood glucose sensors. In one particular example, a relative comparison of a rate of change sensor blood glucose and a rate of change in reference blood glucose may be expressed in a polar plot or graph. The polar plot or graph may then be generated onto a visual medium.
