The Sorting Pop-Up Menu allows you to specify the order in which stations are drawn onto the lineplot. "NO Sort" is the default option, which tells CavePlot to draw stations in the order in which they appear in the survey data. The other options allow the stations to be drawn in the direction selected. For example, choosing "->U" tells CavePlot to draw the lowermost stations first, drawing stations to the lineplot in the order they occur vertically.
These sorting options are helpful in visualizing the 3-D nature of the survey data and lineplot. If the lineplot is drawing slowly (either a big cave or LRCF is selected) you can watch the data being drawn either towards or away from the Screen.
Choosing different Sort options will not affect the survey data itself, or the order in which stations appear in the survey. The only affect is the order in which survey is drawn to the lineplot.
Text, Screen
The Text and Screen color boxes (on the More Option Window) display the colors to be used for drawing text and the grid, and the background, for subsequent lineplots. To change these colors, simply click on the color box and choose a new color from the pop-up menu which appears.
