Channel Plot

The channel plot allows you to map two channels of a video signal on an X/Y axis. The box drawn within the scope helps you determine when your signal will be clipped by a colorspace conversion (gamut errors).

Axis Controls

There are six different channels which may be plotted on either the X or Y axis. These are Y, Cb, Cr; R,G,B; X Y Z; and x y. The channel plot is primarily useful when plotting values within a single color format. For example, you'd generally want to plot R against G or B, rather than against Y,Cb,Cr. By plotting R versus G, and in a second palette, G versus B, you'll be able to quickly judge whether any data will be clipped during the YCbCr to RGB conversion.
