A pop-up menu can be opened by pressing and holding Mouse Button 3 on the product legend for every product you display in the large display pane or the four-panel layout. Simply clicking on the legend performs the default pop-up action, which is the first option in the pop-up menu.

Keep in mind that the changes you make apply to that one overlay and not to all the overlays that are displayed. In fact, the pop-up menu that you open over a particular legend is labeled with the name of that product. Also, the pop-up menus are designed to be dynamic; that is, they respond to any changes you have made and contain new options that pertain to the current state of the overlay.

Exhibit 2.4.1-1, combined from two workstation screens, contains most (but not all) the options available in pop-up menus spawned from product legends.

Note: You cannot open pop-up menus on the product legends displayed in small display panes. However, you can open them on the products themselves. Refer to Section 2.4.3, "Pop-up Menus in Small Display Panes."

All possible pop-up menu options that are available from the legends are discussed in the following sections.

Note: Keep in mind that the options available in the pop-up menus depend on the type of product loaded in the display.

Set Color

The Set Color option allows you to change the color of a single-colored graphic overlay or map background. Once you choose one of the nine colors from the pop-up menu, the selected overlay immediately appears in the new color. If the overlay needs to be displayed in a color other than one provided in the pop-up, the Choose Color option opens the Color Chooser Dialog Box.

Note: The dialog box has the product name in the title bar, not "Choose Color."

• Choose Color: This dialog box, an option from the Set Color menu item and shown in Exhibit 2.4.1-2, allows you to customize the color for a particular graphic overlay.

Like the Image Colors Editor (Section 2.3), the Color Chooser has a Color Wheel, HSB and RGB Check Buttons, RGB or HSB slider bars, and a Color Swatch. Adjusting the Color Wheel Centroid or slider bars generates the desired color in the Color Swatch, or you can enter specific HSB or RGB values.

• OK: Applies the chosen color to the selected overlay and closes the Color Chooser.

• Apply: Applies the new color to the selected graphic overlay.

• Cancel: Closes the Color Chooser without making any color changes.

Edit Colors...

If you press and hold Mouse Button 3, the pop-up menu contains the Image Colors Editor, discussed in Section 2.3, from which you can change the color table. This option is made available in the pop-up menu whenever a single or combined image or multicolored graphic (e.g., time-series Profiler data) is displayed. If a combined image is displayed, the pop-up menu will include the name of each image, from which you can choose to edit.

Change Blinking...

This menu option opens the Image Blinking Dialog Box, as shown in Exhibit 2.4.1-3. It is used to set up the blinking parameters for a single or combined image.  If a combined image is displayed, the pop-up menu will include the name of each image from which you can choose to change the blinking.

The blinking capability allows you to flash selected graphic(s), color(s), and ranges of colors. The blinking rate is adjustable and you can blink several color ranges simultaneously. Blinking features are illustrated in Module 6, Objectives 5 through 7.

The Image Blinking Dialog Box contains the following options.

• Blink Rate: An options menu that contains blinking rates from 0.1 to 2 seconds. Also included is the option to have no blinking, or a zero blink rate.

• Enable Range: This menu button activates the blinking once you select the range of color values you want to blink by dragging the arrows in the color bar to the upper and lower limits of the desired range. You can enable blinking for several color ranges, which then blink simultaneously.

Note: Looping must be turned off for the specified range to blink.

• Disable Range: Disables the blinking only for the range of values within the arrows.

• Reset: This menu button turns off the blinking for the entire color table.

• OK: A menu button that applies the settings you have made and closes the Image Blinking Dialog Box.

• Cancel: This menu button closes the Image Blinking Dialog Box without applying the settings you have made.

Load as Image

This menu option overlays the selected contoured graphic overlay as an image. When you load a graphic as an image with this option, the contoured graphic is still displayed.

Load as Image and Combine

This menu option displays the selected contoured graphic overlay as an image and combines the new image with an already-displayed image. This option is available in the pop-up menu when there is at least one image displayed. To better distinguish and manipulate the combined images, use the options available in the Image Properties Dialog Box (refer to Exhibit 2.1.6.3-10), which is opened from the Toolbar.

Load as Arrows

This menu option displays a gridded vector product (such as wind) using arrows and is available whenever vector fields are displayed. When selected, the wind arrows product is overlaid onto the display.

Load as Barbs

This menu option displays a gridded vector product (such as wind) using wind barbs. This option is made available in the pop-up menu whenever vector fields are displayed. When selected, the wind barbs product is added to the display.

Load as Streamlines

This menu option displays a gridded vector product (such as wind) using streamlines. This option is made available in the pop-up menu whenever vector fields are displayed. When selected, the wind streamlines product is added to the display.

Load as Contours

An option that overlays the selected image field as a contoured graphic.

Line Style

A cascading menu that provides line style settings for a selected graphic overlay. 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.

Line Width

A cascading menu that provides four line-width settings for a selected graphic overlay. Any text or symbols contained in a graphic are not affected by the changes to line style. However, wind barbs and arrows are affected.

Magnification

A cascading menu that provides magnification settings for selected graphic overlays. These settings are the same as those in the Magnification option menu in the Toolbar (see Section 2.1.7). However, the magnification setting chosen from the Toolbar applies to all the overlays in the large display pane, while the magnification setting chosen from the pop-up menu applies only to the one overlay on which you opened the pop-up menu. The present magnification setting of the overlay is indicated with the check button turned on (yellow).

Density

A cascading menu that provides data density settings for a selected graphic overlay. These settings are the same as those in the Density option menu in the Toolbar (see Section 2.1.7). However, the density setting chosen from the Toolbar applies to all the overlays in the large display pane, while the density setting chosen from the pop-up menu applies only to the one overlay on which you opened the pop-up menu. The present density setting of the overlay is indicated with the check button turned on (yellow).

Sampling for this Product

When you press and hold Mouse Button 1 over an image and some plotted data, including METARs, LDAD, marine, severe weather reports, MSAS QC information, and skew Ts, the data value or report will be displayed next to the pointer. You can disable this sampling readout by unchecking the Sampling for this Product button from the product legend.

Blinking

This menu option contains a check button that toggles the blinking of a graphic. It is possible to have several graphics blink simultaneously.

Product Maker Equation

This menu option, available only in conjunction with the Product Maker, is a check button that toggles the generic legend of a Product Maker-generated product to the equation used to generate the product.

Display Product

This menu option contains a check button that toggles the visibility of the selected graphic or image overlay. Clicking Mouse Button 1 on the legend performs the same action.

Unload

This menu option permanently removes a selected graphic or image overlay from the display. The product is restored only by reloading.

Editable

This pop-up menu options apply to editing elements of WarnGen, Interactive Skew-T, and any of the tools that require editing (Baselines, Points, Home, etc.). You can also enable or disable editing of WarnGen and the tools by clicking the legend with Mouse Button 2.
