and here's a `SlicePlot` to illustrate what the missing data looks like: ```python slc = yt.SlicePlot(ds, "x", ("cf_radial", "reflectivity")) slc.set_log(("cf_radial", "reflectivity"), False) ``` 

masking during projection definitely seems like the preferable route -- I only used the projection plots here cause they're easier to see the consequences. If you do just a `ds.proj()`...

Was just poking around this since I was recently looking at that section of code in yt... and the current behavior is certainly confusing. turns out `yt.units.define_unit()` will actually add...

Maybe? As it is, it's more internal infrastructure support than user facing improvements. Most users won't see any changes in behavior -- only those (1) working with gadget and (2)...

Ya, that'd be a good plan! And I just looked through everything again -- getting other frontends to work will take probably more work than is feasible for 4.1. The...

Thanks! responded to some of the questions, will look through the rest of the comments soon. To answer the question of the config options vs frontend attribute: the class attribute...

for context -- added this bug report since it turns out this separate from the now-resolved #4010

comparing `cast_through_kdtree` to `cast_through_octree` in the `ImageSampler`, looks like `cast_through_kdtree` includes a call to `self.extent_function` that has some lens-related logic: https://github.com/yt-project/yt/blob/aeb4d0516ea78ce33d0e18be08e2dece99b2ea58/yt/utilities/lib/image_samplers.pyx#L170-L176 while `cast_through_octree` does not call `extent_function`. Might be a...

Took a quick look, not sure what the fix might be, but here are some notes: `im.write_png` works as expected. The following (from the docstring of `write_png`) works: ```python from...

This error seems to be just that all of the loaders expect the unit parameters to be strings, not unyt units. e.g., ```python ds = yt.load_particles(data, length_unit='parsec') ``` works but...
