The behavior I think it should do is check if it's a tuple, and if it is, either join with spaces or use element 1.

Using the current tip, when I type this: plot = yt.ProjectionPlot(ds,'x',fields=('gas', 'density'), weight_field=None, width=(1.0,'unitary'), center=[0.5,0.5,0.5]).save() everything works fine, and I get a projection. However, when I try this: plot = yt.ProjectionPlot(ds,'x',fields=('gas', 'density'), weight_field=('gas', 'density'), width=(1.0,'unitary'), center=[0.5,0.5,0.5]).save() I get the error: --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-4-7a90d3d7dae2> in <module>() ----> 1 plot = yt.ProjectionPlot(ds,'x',fields=('gas', 'density'), weight_field=('gas', 'density'), width=(1.0,'unitary'), center=[0.5,0.5,0.5]).save() /Users/bwoshea/Desktop/yt-3.0/src/yt-hg/yt/visualization/plot_container.pyc in save(self, name, mpl_kwargs) 464 weight = self.data_source.weight_field 465 if weight is not None: --> 466 weight = weight.replace(' ', '_') 467 if 'Cutting' in self.data_source.__class__.__name__: 468 type = 'OffAxisSlice' AttributeError: 'tuple' object has no attribute 'replace' I would note that if I use 'density' instead of ('gas','density') for the weight_field, everything works fine. Is this the expected behavior, or is this a bug?
