Couldn't you just iterate over a list of data objects, generating a unique FRB in each loop iteration?
Schematically:
objects = [ds.proj(..., weight_field=None), ds.proj(... weight_field='density')]
for obj in objects: ... frb = obj.to_frb(...) ... ds_frb = frb.export_dataset(...)
I don't follow how that gets me something I can hand to PhasePlot. As I understand it, the call to PhasePlot needs to look like
phaseplot = yt.PhasePlot(data_source,x_field, y_field, z_field) data_source needs to be a yt container object, doesn't it?
Yup, I got lazy and didn't finish the script, sorry that wasn't clear:
objects = [ds.proj(..., weight_field=None), ds.proj(... weight_field='density')]
for obj in objects: ... frb = obj.to_frb(...) ... ds_frb = frb.export_dataset(...) ... ad = ds_frb.all_data() ... plot = yt.PhasePlot(ad, ...)
Feel free to stop by IRC so we can hash this out quicker, btw.

In principle we could let the projection object accept a list of weight fields (which is what you want, I think), but that's not how it works right now.
