This paper presents a study on the effects of various data compression methods from the viewpoint of central computer to terminal communications on a large graphics oriented timesharing system, PLATO IV. The desired goal is to increase terminal display speed without significant increase in the transmission error rates. While the major emphasis in…

The plotting of multivariate data using computer line-printers has become a popular means of quickly representing multidimensional data. While many plotting programs are available, there is a paucity of research regarding the validity and reliability of interpretations made by viewing such graphics. This study explores the validity of four…
