Specify conditional formatting in a theme file

Hi everyone,

how can I specify conditional formatting in a theme file?

Specifically, I have specified a conditional formatting for "Bars"-"Colors" like this:

- Format Style = Rules

- Field based on= [FieldName]

- Rules:

  "if value >= ... then colour = red".

  "if value >= ... then colour = "green".

Any suggestions?

Thanks in advance 🙂
