Okay, that makes sense. The override_field attribute looks like an attempt to mark those always-fields as ones that the user really requested, but not fully utilized.

<div class="">Yes, the simple explanation is that fields get added when used in the underlying data source. These fields are used always, when making the image. So without excluding them, they would always be saved to disk.<br class="">

<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="">

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="">
