The red colored countries in the image are countries i consider highly vulnerable to freshwater shortages. I like to have the name of only these highly vulnerable countries appear on the map, i'd be glad to get responses on how to go about this.
Select the Field that contains the country names from the drop-down list of
Label with, and under
Rendering Tab, go to
Show label -> Edit:
and enter the following expression:
"Field_name" = 'High Vulnerable'
Where the Field_name is the field that has the classification of water vulnerability.
Pay attention to the the double quote marks for the field column name and single quote marks for the string value.
There's full support for filtering labels by an expression. In the labeling tab choose "Rule based labling" from the top drop-down". In that window, Click on the green "+" to add a new rule. Then you can use all the expression options to add and format labels. For example, if the water availability is a numeric field, you could enter something like: "water_available" >1000000
Then, of course, choose the country name field as the label.
What's more, you can label different levels of water availability with different color or size labels...
