How to use data_generator with donut?

[henriknordgren]

Since I had little luck with getting this chart to display yearly data properly (separate post), I put together a node red flow that generated correct data for me, and put it in a csv format in an input_text. The data is correct, and now I just want to generate a very simple donut chart with no labels, no titles and no tooltips. I can't even get this to work properly. What is wrong with me? I tried this simple example:

type: custom:apexcharts-card
chart_type: donut
apex_config:
  labels:
    - Qubino
    - Other
  plotOptions:
    pie:
      donut:
        size: 65% 
series:
  - entity: input_text.energy_top_html_table
    name: Energy Distribution
    data_generator: >
      return [[1611718980000, 4.99], [1611743040000, 1.41], [1611763320000,
      4.96]] ;
  - entity: input_text.energy_top_html_table
    name: Energy Distribution 2
    data_generator: >
      return [[1611718980000, 4.99], [1611743040000, 1.41], [1611763320000,
      4.96]] ;

Result:

I have tried many different variants of this code. I dont get why I need the time component in a donut chart, but I added some dummy values just for fun as it is like this in the example readme file. I also tried a more logical approach by just returning the different values [12,12,12,43] for a single entity, but no joy.

So, the million dollar question, what is the proper data_generator return data format for a donut chart?

FInally I managed to display a donut

type: custom:apexcharts-card
chart_type: donut
apex_config:
  dataLabels:
    enabled: true
header:
  show: true
  title: Precipitation Forecast
series:
  - entity: sensor.solaredge_ac_power     
    data_generator: |
      return [[12,80] ];
  - entity: sensor.solaredge_ac_power     
    data_generator: |
      return [[12,40]];

Just like I suspected, the time component is not used, but still needs to be included. The real bummer is that I need to create one serie for each slice in the donut. I render the chart dynamicaly, so sometimes there is one value, sometimes 8 values. Any clue on how to solve that?
