Hi Michael, There are several methods to achieve what you want. It also depends if you want this to be "live linked" with your original points, meaning if you shift the points the buffer circles should automatically adjust or not. Also, if you need this to be "visual only" or if you need real new geometries.
I am listing some of the options here: - Use geometry generators with several buffer expressions (this is visual only, but live-linked to your point geometries) - Use pie charts and feet as units (visual only and live-linked) - Use "virtual layers" and several buffer expressions (this can be live-linked but needs SQL knowledge) - Use PostGIS SQL to create live-linked layers (this can be live-linked but needs SQL knowledge) - Use Processing and the Buffer algorithms - use one of the plugins Personally, I see reason why you'd have to use one of the plugins. QGIS offers everything you need out of the box. Also - for your other question: dissecting into quadrangles - again, there are several options: - use symbol levels and quadrangle circles (these are shipped by default by QGIS). Use expression functions to change size, anchor points and rotations - use the new improvements in QGIS 3.40, stacked partial pie charts (partial pie charts defined by a start and stop angle). See https://www.qgis.org/project/visual-changelogs/visualchangelog340/#feature-introduce-stacked-diagrams - Use the expression function wedge_buffer and geometry generators - Use the wedge_buffer algorithm in the QGIS processing tools I am not going into details about the various methods, unless you tell us more about your needs: - visual only versus real geometries - live-link or not Hope this helps to find the best methods. As always: please also use the excellent documentation at https://docs.qgis.org/3.40/en/docs/user_manual/index.html, consult with video tutorials or consult with your favourite AI tool.
