enter image description hereI am working with the polygon features and I would like the values to be represented in terms of proportional symbols (points). Values range from 0 to 30. I would like that: zero value = no circle; values equal to 1 = small circle; values equal to 2 = ..; values between 2-10 = ..; Over 10 = biggest circle. It is OK to use the same colours for the different dots. How do I do it in QGIS 3.4?


In the layer styling panel, you first select Graduated for your type of symbolisation and then under Method you select Size instead of Color.

enter image description here

You can then change the start and end size, how many classes there are and the color (and shape etc.) of the symbol to get exactly the effect you want.

  • Thank you. I followed your tip but I cannot change the method. It remains on "colour". I added a screenshot.

  • It should work with 3.4 but I would upgrade to 3.10 to be sure
