This invention relates to a method of data output. In data collection and analysis it is often essential that the information be displayed in a two dimensional graphical representation. Each datum is represented by a point (t,u). By displaying each point in the data a graphical image is created. A method is disclosed for improving data delivery of an image to an output device. The method involves grouping the points into columns and selecting 4 points from each column having the minimum and maximum values along each axis. These selected points are then stored. These stored points can then be output to form a two dimensional graphical representation of the data.

Why it's free to use
- Filed April 19, 1996 and granted October 17, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 19, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 19, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
