This question already has an answer here:
I am working with an iron age cemetery in QGIS. I marked every grave in a point layer with several columns; amongst others, burial rite (inhumation, cremation etc.). I inserted a second column for the orientation of the inhumations. I categorized the vector symbols according to the burial rite column and created one simple vector symbol for the inhumations, now I would like it to rotate automatically according to the orientation column.
Is that possible using one layer, or do I have to put all the inhumations in a second layer.
