<H5>Editing Graph</H5>
The graph contains three different pieces of information. The
black line is a representation of the current LUT. The grey
histogram in the background is a histogram of the image data without
the LUT applied and the coloured histogram in the foreground is the
image data with the LUT applied. If the graph is tied to a colour
gun, the foreground histogram is drawn in this colour. A graph that
is tied to a specific channel has its foreground histogram drawn
in dark grey.<p>
The black line represents the values in the lookup table, with the left side
of the graph representing an input value of 0, and the right side of
the graph an input value of 255. The height of the white line above
the bottom of the graph corresponds to the output value. At the
bottom the output value is 0, while at the top the output value is
255.
