[Qgis-user] seeking help on QGIS symbology for clorepleth maps

[Kuan Song]

Hi Andreas,
Thank you for your kind help!About the documentation development, I do have a thought: Wikipedia outgrew Encyclopedia Brittanica by letting users contributing to the evolution of its product. QGIS is a worthy project with limited funding sources.Maybe QGIS could also opensource its documentation and make it a wiki edition? I would surely be glad to join the QGIS-wiki effort.

 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 documentationPlease 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 UIFinally: QGIS is not a product. It is a project - and everybody is welcome to improve and contribute.Hope this helps,AndreasOn 2016-06-14 09:25, Kuan Song wrote:
Dear community, I hope to seek help with QGIS functionality on symbology. The goal is to create simple maps with variable-sized symbols for a polygon map. For example: a map of counties, with bubbles on top indicating the population size in each county. This can be very easily with ArcMap, but is not very easy with QGIS. Yes I know it should be under the 'styles' tab, and it has something to do with adding a new symbol. But the part that's baffling with the user interface is: how do I link a symbol size to a data column in the data shapefile? Yes I know there is a QGIS manual. However, the current manual is very outdated. Many parts of it are simply copies of the manual from older versions, and are utterly useless. For example: http://docs.qgis.org/2.8/en/docs/training_manual/basic_map/symbology.html shows a different UI layout to the current software 2.14.  This is a trivial and elementary problem. I feel ashamed asking this question. I'm sure many people have encountered it before. Could someone point me to a page where I can find a walk-through with actual screenshots of the current QGIS version? That'll be very helpful. Thank you. And again, to the QGIS developers: Please do not let poor documentation ruin a fine software product......  YoursKuan
