[Qgis-user] Proportional Symbols Bug in 3.2?

[Aj Hollenbach]

 Hi QGIS User Community!

I am attempting to represent water utilities (points) using *graduated
symbols* (by size), and would like the symbols to be *proportional* to the
number of customers. I thought that this could be done be done under the
symbology dialogue box by selecting "graduated" and then "size" for the
method while also using the "*data-defined size legend*" option under the
"advanced" sub-menu. However, whenever I click on the "advanced" button and
then select "data-defined size legend", I receive an error message
that "*data-defined
size is not enabled*". Is this a bug in version 3.2, or am I doing
something incorrectly? Alternatively, is there another approach creating
proportional symbols by size for point data?

Thanks Much,
Allen
