The Vertical Cross Section Controls are used to adjust vertical cross section displays. Vertical cross sections can be made in three types of displays: Contour, Color-Filled Contour, and Color-Shaded. The control window has two tabs: Display and Settings. You can change the endpoints of the cross section by clicking and dragging the endpoints in the Main Display window.

The Display tab includes a duplicate of the display in the Main Display window:

• Time Animation Control - Controls the looping of displays through time. See more in Time Animation Control.
• Distance along transect - Depicts the horizontal distance the cross section covers in the Main Display window. This can be changed by left-clicking and dragging the end points of the cross section in the Main Display.
• Location - Displays the location of the end points of the cross section. The endpoints of the cross section can be changed by entering in new values and hitting Enter.

The Settings tab shows the settings for this display control:

• Contour - Sets contour parameters. Click next to Contour to open the Contour Properties Editor. This control can be accessed with the Contour Cross Section and Color-Filled Contour Cross Section views.
• Color Table - Shows the active color table and the associated high and low data values in the units of the display. As the mouse pointer is moved over the color bar, the value at a particular color is shown. Right click on the color bar or click on the button that displays the name of the Color Table to make modifications to the color bar. This allows you to open the Color Table Editor, change the range, select other color tables, etc.
• Visible Range - Sets the range of data displayed when displaying in the Color-Shaded Cross Section view.
• Selector Position - Changes the position of the selector in the main display. You can change this by using the slider or by typing a value into the field and hitting Enter.
• Smoothing - Smooths the grid that can be used to smooth contour lines or flow fields in the display. There are seven types of smoothing: None, 5-point, 9-point, Gaussian, Cressman, Circular, and Rectangular weighted smoothers. The smoothing factor can be adjusted for all except the 5-point and 9-point smoothers. The higher the value, the smoother the grid. For the Cressman, Circular and Rectangular aperture smoothing types, the smoothing factor is the radius in grid spacing units.
• Vertical Scale - Changes the vertical axis range of the cross section.
• Autoscale - Scales the Y-Axis automatically to the data range along the selector line in the display.
• Visible Range - Determines what parts of the data is actually shown. Click the button to set the range of data shown. Once the checkbox is checked, the Visible Range will be applied to the data in the cross section. This is an option in the Color-Shaded Cross Section display.
• Shade Colors - Colors every pixel to give a smooth gradation of color. The alternative is coloring an area of pixels corresponding to a single data grid cell with one color. This is an option in the Color-Shaded Cross Section display.

Many of the menu items seen utilizing this display are standard options that can be found in the Menus section of the Layer Controls Page. However, there are some options that are unique to this display.

The Edit menu has this unique option:

• Change Contours - Opens the Contour Properties Editor to change how the contours appear in the Main Display window. This is an option in the Contour Cross Section and Color-Filled Contour Cross Section displays.

The View menu has these unique options:

• Use Grid Projection - Re-centers the display and resets the zoom level back to the display's initial settings without changing any other preferences you have modified.
• Cross Section - Enables you to capture an image or movie of your display, or open a Properties window which allows you to modify many aesthetic aspects of the Main Display window.
