OH3: Align two y axis

Dear all,

I have a chart in OH 3 with two y axis. One has values from 0 to 3, the other one from 0 to 15. I would like to have the two zeros matched and 3 and 15 matched (already done via min and max for both y axis) both also would like to modify and align the visual horizontal lines within the grid. Any hint how to do so?

config:
  chartType: day
  label: Gas Tagesverbrauch
  period: D
  sidebar: false
slots:
  calendar: []
  dataZoom: []
  grid:
    - component: oh-chart-grid

Thanks and best

I was lucky to find the right documentation in echart: Documentation - Apache ECharts

New yaml if somebody needs it:
