Display Options
The Display Options dialog allows you to configure the appearance and presentation of data in the Ground Reaction View, Tunnel Section View, Info Viewer and probabilistic plots (Histogram, Cumulative and Scatter).
Display Options 
is available in the toolbar, the View menu and the right-click menu on some views (e.g. Ground Reaction and Tunnel Section views).
The Display Options dialog consists of four tabs under the headings:
- Section View
- Plot Views
- Colors
- Number Format
After you make changes to the Display Options, you must select the Apply button to see the changes. If you select the Close button without first selecting Apply, then this will cancel any changes you have made in the dialog.
Section View
The options under the Section View tab are applicable to the Tunnel Section View. Users can control the display of the following attributes: Bolt Length, Bolt Spacing, Thickness of Support, and Other Options.
NOTE: The support display options only affect the graphical display of the support on the screen. These display options have NO effect on the results of the analysis.
BOLT LENGTH
Bolt lengths, displayed in the Tunnel Section View, can be set either independent of the size of the plastic zone, or with respect to the extents of the plastic zone. The Fixed Length option will display bolts with dimensions equal to the length specified by the user.
The Variable Length option allows the user to denote the length of displayed bolts as a sum of the plastic zone thickness and an anchor length beyond the plastic zone.
BOLT SPACING
Bolt spacing is measured along the circumference of the tunnel, between adjacent bolts. The "Actual" option displays all the bolts installed, based on the bolt spacing entered in the Support Parameters dialog. If bolt spacing is considerably smaller than tunnel circumference, many bolts are drawn, and this tends to obscure the view of the plastic zone.
The "Fictitious" option displays the number of bolts specified by the user, irrespective of the actual number installed.
THICKNESS OF SUPPORT
The "Fixed" and "Proportional" options under Thickness of Support control the display of shotcrete and steel sets support. When the "Fixed" mode is selected, the thickness of shotcrete or steel sets, displayed on the screen or printed on paper, is equal to the value specified in mm.
The "Proportional" option displays support thickness as a ratio of tunnel radius.
OTHER OPTIONS
The "Show Ruler" check box toggles on or off the display of rulers on the left and bottom edges of the Tunnel Section View.
The "Show Tooltips for Drawing" option allows Tooltips to pop up whenever the mouse pointer is placed on or near entities such as the plastic zone. These pop-up tips provide users with information, such as radius, on the entities.
The "Show Project Info Text box" option displays the Project Info Text box in the Tunnel Section View. The Project Info Text box contains important RocSupport Project information, such as title, tunnel radius, and a summary of analysis results.
Plot Views
The options under the Plot Views tab are applicable to the Ground Reaction View, and also the probabilistic plot views (Histogram, Cumulative and Scatter plots).
Ground Reaction Curve Horizontal Axis
This option allows you to use either Tunnel Convergence (%) or Wall Displacement (mm) as the horizontal axis for the Ground Reaction View. TIP - the horizontal axis type can also be changed through the right-click menu on the Ground Reaction View.
Colours
The options in the Colors tab control the display of colors in the Tunnel Section View, Ground Reaction View, and Histogram, Cumulative and Scatter plots. Colors can be chosen from the standard palette provided, or from the "More Colours…" dialog.
Number Format
The Number Format tab allows you to control the number of decimal places used for the display of analysis results. This applies to all views of the program, including the Ground Reaction View, Tunnel Section View, Info Viewer, and Histogram, Cumulative and Scatter Plot views.
NOTE: The display of input data values is NOT affected by the Number Format option. Input data values are always displayed using the exact values entered in the input data dialogs (e.g. Tunnel and Rock Parameters dialog).
Defaults
Whenever you make changes to the Display Options (i.e. when you select the Apply button in the dialog), the current display options become the program defaults. If you want to restore the original default Display Options (i.e. when you installed the program), select the Defaults button in the Display Options dialog.
