Here's a brief key, clockwise from the upper left. -- Above the gray "ISF" logo is the indication of whether the chart refers to measurements made at full or half (50 percent on the slider) brightness. Immediately below it is an area for filling in picture setting details; it goes unused for these charts since phones lack those settings. -- The large RGB balance bar graph and the "x, y, Y_" table immediately below shows how black ("0") through gray and finally full white ("100") test patterns measured. Ideally all three of the red, green, and blue bars should be close to "100" on the graph's vertical axis. "Y_" is light output in nits.

-- The second table below the iphone cases bar graph, with the first row listing "white, red, green..100W" shows how the color test patterns measured, -- The "Gamut CIE" diagram is a visual representation of those color numbers, showing how close the measured display came to the target color, Ideally the colored circles should be as close as possible to the squares of the triangle, which represent the sRGB/Rec 709 standard gamut, The same goes for the central white circle, whose target square is the D65 standard white point..

Note that color temperature doesn't appear on this chart, mainly because RGB balance and x/y measurements of white/gray points are more exact. The average color temperature cited in the article was calculated by CalMan using the data shown here. This caption repeats on every slide. For a look at how the averages used in the article's main table were calculated, check out this Google Doc. This slideshow shows the charts from the CalMan 4 software that were used to form the basis of the findings in the article "Screens test: Apple iPhone 5 vs. Samsung Galaxy S3." It contains all of the raw numbers and data gathered from each phone, for anyone who's curious.
