Color threshold apex chart graph

Hello everybody!

I have problems with the color threshold in my graph - I would like to have the negative values red and the positive green. It looks like this:

here is my configuration:

type: custom:apexcharts-card
graph_span: 5h
header:
  show: false
  title: Energie
  show_states: true
  colorize_states: true
series:
  - entity: sensor.template_ueberschuss_bezug
    type: area
    curve: smooth
    name: Überschuss/Bezug
    color: black
    color_threshold:
      - value: -1
        color: red
      - value: 0
        color: green
    stroke_width: 0
    opacity: 1
apex_config:
  legend:
    show: false
  height: 245
experimental:
  color_threshold: true

any ideas?

Try invert: true

like below

series:
  - entity: sensor.template_ueberschuss_bezug
    type: area
    invert: true
