Description

I have joined a vector layer with CSV table values. The attribute table of the joined layer shows all fields as expected.
However, when I try to apply graduated styling QGIS only offers the attribute fields of the 'original' vector layer before joining attributes as basis for styling.

Hm, my SHP-file was too large for upload... so I attach screenshots...

  • Resolution set to invalid
  • Status changed from Open to Closed

this is because csv columns are always treated as text (that cannot be used by the graduated renderer), unless otherwise specified by using a csvt file.
