I have a Deneb spec that I am reusing that, thanks to earlier contributions from @giammariam , is almost exactly what I need:
Until it's filtered (using a slicer) and an extreme outlier (in dark blue) dominates the color scale:
Stakeholders are asking whether each row --across the fiscal years--can be colored independently. In other words, every row would have its own "blueorange" scale (in reverse). I have tried many approaches that have not worked. Here is my spec. Thanks for any help offered.
Adding on to @giammariam, I believe I've done something similar too Independent Scales with Deneb (Ring Chart) - EXPLORATIONS IN DATA STORYTELLING WITH POWER BI (kerryk...

Thanks for the reply, @KerKol. My experience with Deneb is limited, so it's likely I didn't pick the right piece or pieces from your spec.
I adpated this piece of your spec for my visual:
"color": { "field": "__4__", "type": "quantitative", "title": "Marriages", "scale": { "range": [ "transparent", "#de9ed6"
Other than the color scheme, the only difference now was that a rectangle with an underlying value of -17% looks not to be colored.
Hey @Doug7983. Try something like the following. Note - I left comments to show what I updated from my original solution (you'll want to remove comments before migrating to Deneb).

Let me know if this gets you what you're after.
Thanks for the reply @giammariam . As a start, I simply inserted your transform addition block and clicked apply--just to see what would happen. I was surprised--and puzzled, frankly--that nothing happened. (I thought the visual would break because the field references in the transform addition block are different from what I'm using in this visual, a "Growth" field that has been pre-calculated in DAX.)
@Doug7983, there are also additional changes further down for the color encoding. This example is the same one that you used as an example to to build your current spec using your actual data. The transforms and color encoding updates are the only changes. If you update the field names, the color scale domain and range should now be specific to each category.
@giammariam I really appreciate your efforts, this time and previous times you've helped. I think maybe the spec you're working from is off from the one I'm using just enough to make difficult/confusing for me to implement? I'm not sure. Anyway, when I tried this suggestion, everything broke.
I'm not sure if it matters, for instance, but my spec has none of the value block that your's does:
"values": [ { "Date": "11/1/2021", "Category": "Category 01", "Growth (WDC)": "0.23", "Growth (MoYaM)": "0.30" }, { "Date": "12/1/2021", "Category": "Category 01", "Growth (WDC)": "0.12", "Growth (MoYaM)": "0.12" },
<snipped>
I wouldn't know how to do that in Deneb but I have done similar things with the cheapo matrix visual version. Is that an option for you?
Possibly. The out-of-the-box matrix isn't as space-efficient, though.
got some sample data?

Category 2 | 3/1/2024 | 16% |
Here's how the matrix would look like based on your sample data.
Thanks, @lbendlin . This could possibly work, although my stakeholders are used to seeing the Deneb version and change is hard. I can't get the DAX to work, though. Maybe because "Change" in my data set is a DAX expression and not a column?
