Use this button to go from the (Lineplot) Options Window, to the More Options Window, a whole other page of lineplot options. The options here are used less frequently and take more room, so they get their own window. Here you can select which set of sections to use for coloring the lineplot, how you want the LRCF data displayed, whether to display a compass on the lineplot itself (and on printer output), specify a station to center the lineplot on, select colors and depths for color-by-depth lineplot coloring, specify text and background (screen) colors, and various other less used options.
