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.

A system for displaying a diagram representing a plurality of parameters, comprising:
- means for receiving a raw value for each parameter;
- means for determining a mean normal value and a standard deviation of the mean normal value for each parameter;
- means for computing a normalized parameter value for each parameter, the normalized parameter value being a function of said raw value, mean normal value and the standard deviation of the mean normal value;
- means for computing a displayed parameter value for each parameter as a function of the normalized parameter value using a range restricting function;
- means for displaying three concentric circles with a common center, wherein the inner circle represents the mean normal value minus the standard deviation, the middle circle represents the mean normal, and the outer circle represents the mean normal value plus the standard deviation;
- means for generating and displaying a plurality of spokes having a plurality of lengths, the number of spokes being equal to the number of parameters and the length of any of said spokes being equal to selected ones of said displayed parameter values;
- and,
- means for forming a plurality of rays located between two adjacent spokes, the length of each ray being a function of a weighted sum of the spokes's length.
A method for displaying a plurality of parameters comprising:
- (a) receiving a raw value for each parameter;
- (b) determining a mean normal value and a standard deviation of the mean normal value for each parameter;
- (c) calculating a normalized parameter value for each parameter, the normalized parameter value being defined according to:

- DPV=A* arctg(B * NPV−C)
- where
- DPV is the displayed parameter value,
- A, B and C are experimental constants, and
- NPV is the normalized parameter value.
