Is there a simple explanation for why they can’t be treated as normal fields and what that refactoring would look like?

<div class="">SlicePlot suffers from the same issue for the same reason (it’s getting dropped at the PlotWindow stage).</div>

<div class="">This is due to implementation details in the PlotWindow class. It would take some refactoring to allow plotting these fields. Patches welcome :)<br class="">

Yes, this is frustrating, and I have been bitten by it.<br class="">

New issue 937: to_pw silently drops some fields<br class="">

Douglas Rudd:<br class="">
<br class="">
to_pw silently drops fields from frb._exclude_fields and _key_fields without notifying the user.<br class="">
<br class="">
```<br class="">
#!python<br class="">
<br class="">
>> ds = yt.load("outputs/sedov_000960.<u class=""></u>art")<br class="">
>> fields = ["density","temperature","dx"]<br class="">
>> plot = ds.slice(2, ds.domain_center[2]).to_pw(<u class=""></u>fields)<br class="">
>> print plot.fields<br class="">
['density', 'temperature']<br class="">
```<br class="">
<br class="">
In this case ('index', 'dx') is in both exclusion lists. Any reason I can't plot a slice of my resolution?<br class="">
