POLYSCORE Polygraph Software was created by the Applied Physics Laboratory at Johns Hopkins University. The latest version of POLYSCORE is now Windows based for ease of use. It allows you the ability to view and print stacked charts. Another feature that examiners will find valuable, is the on-screen color-coded bar graph display. This feature makes it very easy to graphically display reaction strengths, allowing for easy public / novice interpretation. Additionally, by upgrading to this version of POLYSCORE, current LX users will now be able to fully utilize all of its previously unavailable features.
