Hi Kuan, There is a newer manual available (still under development), targetting version 2.14. You can find it at http://docs.qgis.org/testing/en/docs/
For your specific problem - have a look at the "Size assistant": http://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/vector_properties.html#proportional-symbol-and-multivariate-analysis When you complain about the poor state of documentation, there are multiple ways of contributing: - help improving the documentation by providing pull requests - donate some money so others can work on documentation - hire a person that improves certain aspects of the documentation Please do not compare ArcGIS with QGIS documentation - because ArcGIS documentation is created from a company with approx. 3200 employees and annual revenues >1 billion US $ per year, whereas QGIS is run primarily from part-time developers and volunteers - with available funds and sponsored development in the lower 6 figure euros per year - distributed over several companies and the global QGIS.ORG organization. Also - please understand that - unlike some other companies or projekcts - QGIS is not copying ArcGIS - so it is quite natural that the terms are different, as well as the UI Finally: QGIS is not a product. It is a project - and everybody is welcome to improve and contribute. Hope this helps, Andreas On 2016-06-14 09:25, Kuan Song wrote: > Dear community, > > I hope to seek help with QGIS functionality on symbology.
