I have downloaded my elevation points from website Natural earth data (at a scale 10 Million), I wanted to display my elevation points like this in 3 classes:
1) Elevation points, symbol('+') and name of elevations (with Label)
2) Elevation points, symbol('+') (without label)
3) Depression, symbol('-') (without label)
I've tried them as in rule-based in "Style" and "Label" (see please screenshot),
Properties > Label
Depression (supposed to show only '-32' not with symbol'+') [is just one of an example]
but it doesn't show me on the map correctly, how to classify them into 3 different group (as I mentioned above)?
