[Qgis-user] styling type

[Sturm Noemi]

Hi Lene

Thank you for your answer.
Actually I would like to know if either rule-based styling or categorized styling renders faster.
e.g.
Postgis-Layer with attribute "size". Attribute values of "size" are "small", "middle", "big".
In categorized I would categorize by "size". In rule-based I would write 3 entries like "size" = 'small'.

Regards,
Noëmi Sturm

Hi Noëmi,

Use Classifying
Look at QGIS training manual: https://docs.qgis.org/2.18/en/docs/training_manual/vector_classification/index.html
Or  Klas Karlssons multiple videos

Subject: [Qgis-user] styling type

Hi

I'd like to style objects of a postGIS-Layer upon values of a single attribute. Which styling type (rule-based or categorized) should I use in respect of rendering performance (QGIS 2.18 and QGIS Server 2.18) ?

Thanks,
Noëmi Sturm
