By design, missing data will disappear from the view. In this example, workaround this design by adding Countries with the value 0 in a new Sheet in Excel, and then joining the data with a master table of Countries. The data and the workbook can be downloaded from this article (in the top right corner).
  1. In this example, ensure your data source contains a sheet all required countries and Zero (0) values assigned to them
  2. For this example, we're adding the data source again a new data source
  3. Join both sheets from the data pane using the Country field
  4. Build the map view, add the Value from Sheet 2 to Color
  5. Drag the Country field from Sheet 1 to Details

Additional Information

The same result can be achieved with only one sheet of the data, which will need to be related it to itself.
