Using Graduated Symbols in QGIS

This video covers how to use graduated (categorized) symbols in QGIS instead of standard markers. This is an easy way to add visual interest and additional explanatory power to a map.

As someone else already mentioned in the comments, graduated symbols are only available for point features, not polygons. So first you should create a points layer by using the "Centroids" geoprocess.

Thanks so much, I am trying to overlay state level excel data on my country shape file. I can't get the size option though. Only the color option. Could you please help?

[@jesrielc.casinillo9421]

what if my qgis doesnt have method option where i can choose between colors and size?

Im having the same issue with QGIS version 3.30.2, if you find a way to change the method could you please share it here too once? Thanks a ton in advance!

@@doctorkash0792 i got consulted it to my prof and he only did is to make a dot and save it and then layer it, not a polygon.

Make sure you've selected Graduated from the top menu, not Categorized or Single Symbol. I just tried it with 3.30.2 and the menu showed color and size. I'd also suggest reinstalling QGIS to see if that makes any difference.

I realized that the method selection is available for point features not polygons.

[@doctorkash0792]

I don’t have the method selection in my symbology, you have any idea what else I can do to change the method? I have QGIS Version 3.30.2, anyone else has any idea what to do?

[@jesszimmerman684]

Can you send me your QGIS project file? Send it to [e-mail].
