The latest version of Polyscore is now Windows-based for ease of use. It allows polygraph examiners 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. Polyscore is developed by the Applied Physics Laboratory at Johns Hopkins University, USA.
