The following sections contain brief descriptions of each menu and icon button displayed along the second row of the menu options, called the Toolbar, on your workstation screen. Refer to Exhibit 2.1.7-1.

Certain icon buttons in the Toolbar are check buttons. These icon buttons turn a light gray color when they are in the "on" position. Tooltips appear as you slowly move the mouse pointer over the Toolbar icons.

Load Modes  

Load Modes provide different ways to display model or real-time data by manipulating previous model runs and inventories of data sets. Refer to Exhibit 2.1.6.3-6 for an example of the Load Mode option menu, as seen in the workstation's large display pane. The Load Modes are defined in Section 2.1.6.3 Options and covered in more detail in Section 3.1 The Volume Browser.

Scale  

From this menu you can choose one of six scales: Northern Hemisphere, North American, CONUS, Regional, State(s) or RFC, and WFO. Refer to Exhibit 2.1.6.3-5 for an example of the Scale option menu.

When D2D is first started up, the CONUS Scale is displayed in the large display pane and other scales' map backgrounds are loaded into the four monitor panes. However, you can use the Scale option menu to choose any scale for any of the five display panes. The Scale option menu affects only the main pane. A swap is required to change the scale on a monitor pane.

Once data have been loaded, changing the scale does not affect the large display pane until you display a product or clear the screen. It does affect what products are available in the menus. In other words, product availability is scale-dependent.

Clear  

This button, which turns red when the mouse pointer is over it, clears the large display pane. The map background remains.

Stepping  

This set of four menu buttons allows you to Step Backward (<) or Step Forward (>) through multiple frames of data, one frame at a time, or to move immediately to the First (|<<) or Last (>>|) frame in the loop.

Loop  

This icon button toggles looping in the large display pane.

Toggle Image Combination  

This icon button enables/disables the ability to display two images at one time.

Loop Properties  

This icon button opens the Loop Properties Dialog Box, as described in Section 2.1.6.3.

Image Properties  

This icon button opens the Image Properties Dialog Box, as described in Section 2.1.6.3.

Print  

This icon button prints the contents of the large display pane on the default printer. See Section 2.1.6.1 for how to change printer destination.

Points  

This icon button displays the Interactive Points Tool, as described in Section 2.1.6.4.

Baselines  

This icon button displays the Interactive Baselines Tool, described in Section 2.1.6.4.

Five-Pane Default Layout  

Clicking this icon button arranges the default display to have one large display pane and four small monitor panes. Refer to Exhibit 2.1.6.2-2.

Three-Pane Layout  

Clicking this icon button arranges the display to have one large display pane and two medium-sized monitor panes. Refer to Exhibit 2.1.6.2-3.

Frames  

Use this option menu, shown in Exhibit 2.1.6.3-7, to select the number of frames of a product you want loaded. The default is 12 frames. The maximum is 32 frames. The actual number of frames loaded is indicated in the status bar at the bottom of the display.

Magnification  

Using the Magnification option menu (Exhibit 2.1.6.3-8), you can enlarge or reduce the size of the text and symbols on a graphic product. As you increase magnification, the density of the data automatically decreases. The purpose of this feature is to make the text and symbols more visible. Magnification 0 is a special case. For station plots, only the location of the station is shown, and stations with data are in the overlay color, while those without are gray. You can still sample the data in this mode. For grids, you can see the grid resolution by displaying wind and setting magnification to zero.

Density  

Use the Density option menu (Exhibit 2.1.6.3-9) to adjust the amount of data presented on the large display pane. Higher density settings increase the amount of data.

Width  

This options menu provides four line-width settings for all the displayed graphic overlays and map backgrounds. Any text or symbols contained in a graphic are not affected by the changes to line width. However, wind barbs and arrows are affected.

If you want to change the width of only one graphic, press mouse button 3 over the legend of the desired overlay to open the pop-up menu which contains the line width options.

Style  

The options in this menu provide line style settings for all the displayed graphic overlays. The options are Default, Solid, Dashed, or Dotted. By default, data with values less than zero are automatically displayed in dashed lines. Any text or symbols contained in a graphic are not affected by the changes to line style. However, wind barbs and arrows are affected. If you want to change the style of only one graphic, press mouse button 3 over the legend of the desired overlay to open the pop-up menu which contains the style options.
