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"
      },
