The Chroma and Lightness plots he Measure coordinates, plotted against the Reference coordinates set at
the origin of axes. Also the three Acceptance Thresholds are displayed as boundaries in these plots. The graphs and
the coloured ticks (Red/Green for a*, Yellow/Blue for b*, Black/White for L*) help the user to understand which
component is the prevalent source of colour difference between Measure and Reference.
