Open the CIPO recordAbstract From the Canadian patent
A computer implemented method for displaying multivariate data. Display values are plotted on respective axes which run radially in a predetermined direction from a common centre point. The display values are computed from sample values by performing a mapping and normalization function. Display values which are plotted outside a defined normalization circle represent error conditions while display values which are plotted inside the normalization circle represent acceptable conditions. Colour may be used to enhance the information content of the display. An operator may infer the state of the system simply by observing the shape of the display.

Why it's free to use
- Filed October 13, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 13, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 13, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
