The user specifies two variables, one for the x axis and the other for the y axis. These variables are given minimum and maximum values and their values are changed accordingly when the data points for the 3-dimensional graph are produced. Other variables are kept at the values of the current base point. The slide bar plot intervals specifies the number of grid points for both the x and y axis.
The buttons that are disabled become enabled when planting density or thinning percentage are selected.
The button Base point invokes the window with which other variables of the silvicultural regime can be set. The Generate button invokes the program xprism3 of the Khoros visualization system with input data produced by the stand simulator. A sample graph is shown below.
Many of the properties of the graph can be adjusted via Khoros control functions. The graphs may be saved to files or plotted on PostScript color or monochrome printers. There is also an extensive help facility associated.
