[Qgis-user] Proportional Symbols Bug in 3.2?

[Aj Hollenbach]

Hi Nicolas,

I looked at the dataset and the "total served" by the water utility is
indeed in an Integer format. Any other ideas on what might be preventing
the use of proportional symbols? Perhaps this is bug with this version of
QGIS?

Thanks Much,
Allen
