How to chart Switch item like Analyzer does

I have a chart with already two scales that I want to add a switch type item to just like analyzer displays it if you analyze-chart that item: as a bar reaching from bottom to top of the chart, no matter the scale.
Any idea what’s the golden option I’m missing?

Hi Markus

Something like this?

If yes –> markArea:

    - component: oh-time-series
      config:
        gridIndex: 0
        name: Pumpe läuft
        type: line
        xAxisIndex: 0
        yAxisIndex: 0
      slots:
        markArea:
          - component: oh-mark-area
            config:
              item: Pumpe_Laueft
              name: Status

ah, yes! Thanks a lot!
