Here's what I see: * On Unbuntu 10.04, QGIS 1.7.2 I get the above problem. Query first, then Classify doesn't work - no reponse to the Classify button * On OSGeo Live 5.0 ... same problem * On Windows 7, OSGeo installer v. 1.7.1 same problem * On Scientific Linux 6.1 with _self compiled 1.7.0_ the above problem does *not* happen. I can query first, then classify, or the other way. * WinXP with OSGeo 1.7.2 ... same problem I don't know if it's relevant, but all the above were with layers in Spatialite. -- Micha cheers -- Giovanni -- This mail was received via Mail-SeCure System. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

This is tricky: if you select advanced - select scale field *before* hitting classify then the size symbols won't be scaled.

Re: [Qgis-user] graduated symbols for point layers
I've gotten the graduated symbols to work after discovering the trick Giovanni mentioned, but now my problem is that they don't show up as graduated by class, but rather by each individual quantity. This is a problem because my quantities range from 50 to 2,800, so I'm not able to get something that's neither too big nor too small. Also they don't show up as graduated in the legend, so I've had to create the legend piece by piece.

What you can do is go back to the old symbology, and categorize your symbols as you did at first. Then just double click on each symbol to individually set it's size (and color, etc).
