I am trying to do rotation of point symbols in QGIS. I am working with rule-based renderer. In other types of classification there is a button advanced (for example in categorized renderer), where I can choose rotation field. But in rule-based renderer this button is missing.

Do you know how to make this rotation of point symbols otherwise?

Example in categorized renderer enter image description here

In rule-based renderer advanced(and rotation field) is missing enter image description here

I figured out how to do it manually. Not so ellegant, but works.

In *.qml style, I can edit part with

< prop k="angle" v="0"/ >

and instead of it write

< prop k="angle_expression" v="ROT"/ > , where ROT is my field with rotation.

Edit: In version 2.10 there is a new field in rule-based renderer- "change angle". enter image description here

You can find the Advanced options if you click on a rule you made and select Refine current rules > Add categories to rule or Add ranges to rule > Advanced > Rotation field:

Advanced options

Hope this helps!

  • Thanks! But still I have a problem, because I am rotating font markers and it doesn't work in rule-based renderer. When I try your solution with predefined Qgis markers- it works, but it doesn't work with mine own markers. I think that this is maybe QGIS bug or something is wrong with my fonts... :-/

  • @Kristy - I am not sure as I never really worked with the rotation options, I just remembered that there was an option for it. Hopefully others can advise =)

    @Kristy please try the latest version of QGIS and report a bug if this is still a problem. Thanks!
