constructing a legend for coloured circle scatter

I could guess at what you are trying to do, but it would help a lot if
you posted an example that we could run, with comments about what you
want to happen versus what is happening.

Have you seen examples/legend_demo2.py, which illustrates how to make
legends for a subset of objects in the plot?
