Unidata IDV Workshop for version 3.0u2 > Accessing and Displaying Data > Working with Gridded Data

When a display is created, an entry for it is added into the legend panel. There are two types of legends, side and bottom, that you can use to show the displays that are in a view. You can define which type of legend should be used. The side legend, shown below, is the default legend style. Main features of the side legend are:

• Display Categories Each display has a Display Category that allows grouping of similar displays. The category can be changed as we saw in the previous exercise. Each category label includes a toggle button for collapsing or expanding the category details as well as a visibility checkbox for toggling the visibility of all displays in this category.
• Display Legends Each display has it's own legend
  
  
  consisting of the following parts:
  • A label for each display The label includes:
    • A toggle button for collapsing or expanding the display details
    • A visibility checkbox for toggling the visibility of this display,
    • The name of the display . Left clicking on this will bring up the the display's control window. Right clicking will bring up the control menu. The name of the display can be changed through labels through the Display Control Properties editor (Edit->Properties).
    • A visibility toggle lock which locks/unlocks the toggling of visibility for this display.
    • A remove button for removing the display from the view window.
  • Extra descriptive information about the display. This may include the full name of the parameter and ancillary information like the vertical level. You can add your own extra legend labels through the Display Control Properties editor (Edit->Properties).
  • Color bar (optional) - for colored displays, shows the color table being used and the range that the colors span. Right clicking on the color bar brings up a menu for changing the color table.

Things you can do with the side legend:

1. Toggle visibility - Uncheck the visibility toggle checkbox to make the display invisible. Click again to set it visible.
2. Change the color table - Right click on the legend color bar to bring up the color bar menu.
   • From the menu, select the Solid->Yellow menu item.
3. Show the Display Control Window - Right click on the display label to bring up the display control menus. These menus are the same as those accessible through the control window. Select the Control Window menu item to bring the control window to the foreground.
