I used a multicolor chart to view the vector scope. When I crop it to view each color by itself, I see a nice line originating from the center of the vector scope and projecting towards one of the color boxes. But if I view the entire chart with all of its colors, there are only two lines originating from the center and a lot of the lines just connect one color box to the adjacent color box.

For the attached screenshot, the scope shows a line connecting the blue to the green, the cyan to the red and the yellow to the magenta. The only two lines that start at the center are the red and cyan. Why does the line behavior change when only one color is viewed vs all the colors ?
