1. The answer is:
• The color table is the default color table.
• The range used is the range from the actual data.
2. The problem is that the IDV does not recognize that the name of the temperature at fixed height above ground field as a temperature.
3. To solve this problem, the IDV provides a data alias facility.
4. First we need to know the actual parameter name, not its description.
   • Select the Help→Details menu item from the Color-Shaded Plan View display control that was just created.
   • You should see a detailed description of this display, including the data it uses:

   ...
    T_fhg temperature at fixed height above ground from Geogrid data source
   ...
   

   • The parameter name is T_fhg.
5. Open up the Alias Editor from the Tools→Parameter Alias Editor menu.
• You should see 2 tabs: User Aliases and System Aliases
• The first tab shows the user's editable aliases. The second tab shows the default system aliases.
• Select the System Aliases tab.
• Right click on the TEMP row and select Edit Alias.
• You should now see this row in the User Aliases tab and the Data Alias dialog should be shown.
• Scroll down to the bottom of the Aliases list, enter "T_fhg" and click the OK button.
• Click the Close button in the Alias Editor window.
• To edit an existing entry right click or double click on the parameter.
6. Let's see if this works.
• Remove your displays by selecting the Edit→Remove All Displays menu item.
• Create a Color-Shaded Plan View display with a temperature at fixed height above ground parameter.
• You should see the Comfort color table and the correct range being used now.
