Aggregation of bar charts in OH4.3?

Hi,
I’m using a “bar chart” which doesn’t look like one because every single measure is a bar - and over a day it looks like an area chart:

config:
  label: Chart Stromverbrauch
  period: D
  chartType: day
slots:
  grid:
    - component: oh-chart-grid
      config:
        show: true
  legend:
    - component: oh-chart-legend
      config:
        orient: horizontal
        show: true
  series:
    - component: oh-time-series
      config:
        areaStyle:
          opacity: 0.2
        color: orange
        gridIndex: 0
        item: Balkonkraftwerk_Solar_shellypmmini6055f99fdf1019216810191_Stromverbrauch
        lineStyle:
          width: 2
        markLine:
          data:
            - type: average
        markPoint:
          data:
            - name: min
              type: min
            - name: max
              type: max
          label:
            fontWeight: bold
          smooth: true
        name: Balkonkraftwerk
        type: bar
        xAxisIndex: 0
        yAxisIndex: 0
    - component: oh-time-series
      config:
        areaStyle:
          opacity: 0.2
        color: red
        gridIndex: 0
        item: Shelly_3EM_Haus_shellyem3c45bbe6a867d19216810173_Kumulierter_Verbrauch
        lineStyle:
          width: 2
        markLine:
          data:
            - type: average
        markPoint:
          data:
            - name: min
              type: min
            - name: max
              type: max
          label:
            fontWeight: bold
          smooth: true
        name: Gesamtverbrauch Haus
        type: bar
        xAxisIndex: 0
        yAxisIndex: 0
    - component: oh-time-series
      config:
        areaStyle:
          opacity: 0.2
        color: blue
        gridIndex: 0
        item: Gesamtverbrauch_ohne_Solar
        lineStyle:
          width: 2
        markLine:
          data:
            - type: average
        markPoint:
          data:
            - name: min
              type: min
            - name: max
              type: max
          label:
            fontWeight: bold
          smooth: true
        name: Gesamtverbrauch ohne Solar
        type: bar
        xAxisIndex: 0
        yAxisIndex: 0
  xAxis:
    - component: oh-time-axis
      config:
        gridIndex: 0
  yAxis:
    - component: oh-value-axis
      config:
        gridIndex: 0
  dataZoom:
    - component: oh-chart-datazoom
      config:
        show: true
        type: slider
        orient: horizontal

My question: Is there a simple way (like a parameter in the code) to tell the charting engine to aggregate bars e.g. on hourly level? And if so - do you have an example at hand?

Thank you!
