Scratch that, my fixes are for the volume renderer.

<p dir="ltr">It's a bug. It is assuming that weight field is a string, but it's a tuple. 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.</p>

<div dir="ltr">Hi folks,
<div><br>
</div>
<div>I am having a problem making weighted projections in yt-3. Using the current tip, when I type this:</div>
<div><br>
</div>
<div>plot = yt.ProjectionPlot(ds,'x',fields=('gas', 'density'), weight_field=None, width=(1.0,'unitary'), center=[0.5,0.5,0.5]).save()<br>
</div>
<div><br>
</div>
<div>everything works fine, and I get a projection. However, when I try this:</div>
<div><br>
</div>
<div>plot = yt.ProjectionPlot(ds,'x',fields=('gas', 'density'), weight_field=('gas', 'density'), width=(1.0,'unitary'), center=[0.5,0.5,0.5]).save()<br>
</div>
<div><br>
</div>
<div>I get the error:</div>
<div><br>
</div>
<div>
<div>---------------------------------------------------------------------------</div>
<div>AttributeError Traceback (most recent call last)</div>
<div><ipython-input-4-7a90d3d7dae2> in <module>()</div>
<div>----> 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()</div>
<div><br>
</div>
<div>/Users/bwoshea/Desktop/yt-3.0/src/yt-hg/yt/visualization/plot_container.pyc in save(self, name, mpl_kwargs)</div>
<div> 464 weight = self.data_source.weight_field</div>
<div> 465 if weight is not None:</div>
<div>--> 466 weight = weight.replace(' ', '_')</div>
<div> 467 if 'Cutting' in self.data_source.__class__.__name__:</div>
<div> 468 type = 'OffAxisSlice'</div>
<div><br>
</div>
<div>AttributeError: 'tuple' object has no attribute 'replace'</div>
</div>
<div><br>
</div>
<div>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? </div>
<div><br>
</div>
<div>Thanks!</div>
