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 > Style enter image description here

Properties > Label

enter image description here

Depression (supposed to show only '-32' not with symbol'+') [is just one of an example]

enter image description here

but it doesn't show me on the map correctly, how to classify them into 3 different group (as I mentioned above)?

You should specify an expression in 'Rule' section like "elev_hoel" > 0.

These expressions are similar example for styling:

For labelling, an expression in 'Rule', preferably same expression in styling, and text format you want in 'Text' section.

Depending on field type, you may need to use/remove to_int and to_string.

  • Hi Kadir, Thanks for your replying! Which one (both?--"elevation" which is with name and "elevation2" without name/label) shall I change to "elevation_hoel >0"? and why (elevation_hoel >0)? because in my screenshots first and second, the first rule is with name, the second rule is without a name, third is depression. 2. depression: the red line is the symbol? – ndr Apr 30 '18 at 9:59
  • These are just similar examples. I don't have your data, so that, it's hard to write perfect solution for your problem. "elevation" and featurecla are field names as shown in first figure (look at the attribute table). double quote is optional for field name. featurecla equals "featurecla". First figure is for styling, second is for labelling. (please hit F7 key to view "Layer styling" panel. By this panel you see instantly changes you made) – Kadir Şahbaz Apr 30 '18 at 10:15
