Abstract
A system and method for displaying parameters in a smoothed normalized star diagram where parameters are received from a medical laboratory instrument and processed. The processing includes calculating a normalized parameter value for each parameter using a predetermined mean and standard deviation and scaling the resulting normalized parameter value using a range restricting function. Each scaled parameter is assigned to a spoke and rays are drawn between adjacent spokes at a small angular interval. The ends of the rays are then joined by line segments, thereby constructing a smooth overall diagram.
