The left of the plot is the bottom of the screen and the right the top. Each red, green, or blue subpixel has an intesity between 0 (full dark) and 255 (full bright). For the address system I was using, image pixels at the bottom have a Y address of 0 and at the top 2447. The screens on the 2 readers have Y (vertical) image addresses of about 500 to 2000.
The plots show the red, blue, and green intensities for a column of pixels located in the margin part of the page from the bottom of the page to the top. So the blue is weaker at top of the Voyage screen and the blue is a bit stronger at both the top and bottom of the PW2 screen.
It happens that in this particular image, the Voyage is brighter than the PW2, so none of the points are mixed and 6 colors for the points are not needed, nor do the plots need to be offset from each other.
Averaging several columns together and averaging along the columns would smooth the plots, but I don't have time for that at the moment.
