This image displays a horizontal polygraph chart printed on a long strip of cream-colored, grid-lined paper. The chart features two distinct continuous line recordings in dark ink that span the length of the page. The top recording shows a high-frequency, consistent zigzag pattern representing respiratory or pulse data. The bottom recording is a thicker, more irregular line with larger fluctuations and peaks, indicating variations in physiological responses. Several vertical black lines intersect the horizontal data at irregular intervals, likely marking specific moments or questions during the test. In the lower-left corner, there are handwritten blue ink notations and a small circular purple stamp. Centered along the bottom edge of the paper strip is a professional color calibration scale containing a row of colored squares followed by a grayscale gradient from white to black. The entire chart is set against a dark, neutral background.
