Chapter 8
	Viewing Soil Moisture Profiles
	Sections 8.1 to 8.3 (8.3.1 to 8.3.6)

To run Topog_Profile type: $_profile

Two major windows appear (see Figure 8.1) which we refer to as the display window and the menu window.

The display window is split into four plot frames (the default arrangement) where the plotted data appears.

The menu window is divided into three main areas. The function buttons area contains a series of buttons which, when clicked on, initiate program commands. Details of the specific functions of each button area are given in section 8.3. The information area is used to display results of data file interrogations. It is also used to display colour and line/point/pattern style palettes. The selection area is used primarily to select an attribute to plot from a list of the appropriate files or items.

Functions in the menu window are invoked by pointing and clicking with the mouse. After a function is selected a function window appears listing the available options. When a required option is clicked on, its highlighted; indicating that the option has been selected. Click OK for that option to take effect then Cancel to clear the window. Note that the Help button has no effect (at this stage) as all options are listed and are self explanatory.
