1. Setup...
   • We are going to load in two different "NCEP NAM CONUS 80 km" model runs from the Catalog chooser under the IDV catalog. e.g., choose the 0Z and the 12Z.
   • Create a Contour Plan View of Temperature from each model.
   • In one of the displays change the Contour interval to be 3, change the color table to some other color table (e.g., VisAD), change the level to 500.
   • Add in some Location display (i.e., from the Display→Special→Locations menu).
   • Add in a Range and Bearing display.
2. Note we can't really have an apples to apples comparison of the two Contour displays because they differ in the interval, color table and level.
3. We could go and change these settings in one of the displays to match the other but imagine if you had, say, 4 displays to change. Lots of clicking.
4. Instead, go to the Edit→Display Settings menu for one of the contour displays to bring up the Display Settings dialog.
   • The Display Settings dialog shows a list of properties from the selected display (highlighted in blue).
   • Note how the Display Groups under menu Select can be used to select different groups of displays.
   • Select both of the Plan View Contour displays in the Target Displays panel.
   • Change the highlighted display by right-clicking on another one in the list on the right and view the new Property values on the left.
   • Highlight the "500 hPA" Contour Display.
   • Select the Color Table, Contour Settings and Level properties on the left.
   • Press Apply to apply these selected properties to the selected displays.
5. We can also save the selected properties and use them when creating a new Display.
   • Select the properties you want to save (e.g., Level, Color Table, etc.)
   • Press File→Save Selected Properties
   • In the dialog enter "Workshop" for the category and "500 MB Contours" for the name. Select Applicable only to displays of type...
   • Press OK and then close the Display Settings dialog.
6. Go to the Field Selector, clear the existing displays and select Contour Plan View.
7. In the Settings tab select the "500 MB Contours" and create the display.
8. Note the results.
