Use the "Small X" and "SICN's" radio buttons to tell CavePlot how to draw stations on the lineplot. They may be drawn either as all small X's, or with each station using its own previously selected SICN pattern (currently 50 different patterns to choose from).
The "Show Text" button, if selected, tells CavePlot to draw some explanatory text on the lineplot. This text includes the survey name, length of survey turned on, lineplot orientation, grid scale, and lineplot scale.
The "Small Text" button, if selected, tells CavePlot to draw the explanatory text, station names, points, and orientation compass, at only half size. This is not very helpful when drawing to the screen, but looks much better when printing at high resolution on a laser printer.
The "Page" and "Page/2" buttons tell CavePlot how much to move when scrolling the lineplot. "Page" moves a whole screen (page) at a time, while "Page/2" moves only half a screen at a time.
