3.7.4 More on the Layout Model Editor
Let's find out why there isn't anything displayed.
  1. Bring up the Workshop layout model again.
    • From the Point Data Plot display control window click on the edit image: .
    • Bring up the Properties dialog for the symbol by right clicking on it and selecting the Properties... menu item.
    • Note that the name of the parameter we are using is "IDN".
    • Press the Cancel button to close the dialog.
  2. Now, back to the Point Data Plot control window let's see what parameters are available in the data set.
  3. Once again, back to the Layout Model Editor.
  4. Now, how do we handle the case where we have lots of layout models for data that has "ID" like fields and then we encounter data with some other field name, e.g., "the_station_id"? Do we go and change each and every model?
  5. Now, let's spend some time in building some other layout models.
    • Start fresh. Show popup
    • Go to the CONUS projection with the Projections->Predefined->US->CONUS menu item.
    • Load in US city locations with the Displays->Locations->US->U.S. Cities menu item.
    • Select the Layout Model button.
    • Edit the Location layout model.
    • Try adding a Shape shape.
    • Select some shape and press Apply
    • The location has a pop attribute. Try scaling the shape this value.
      • Go to the Scale Size By tab in the Properties Dialog
      • Enter pop for the parameter.
      • In Data Range enter 1000000 in the second field.
      • Enter some scale range. e.g., 0.5-5.0
      • Press Apply
    • Try doing a color by pop
