The "xy graph" tab is added to a Compare window when the compare file is generated from a Quick-Test Display-Check, and when Neutral and RGB ramps are measured; these combined ramps are shown as “Neutral + RGB” in the Display-Check Quick-Test menu. You can compare your measurements with one of five reference RGB spaces, displayed as a light gray triangle, and see where your display White Point falls on the D- series or blackbody (Planckian) Illuminants loci. In this screenshot, we see the results of measurements done on a Dell U2410 wide gamut display; this display's primaries are very close to the ones of the Adobe RGB space.
