    row["Preis3"] = 35
    sampleData[i]= row
  Next
  
  Chart1_settings.source = sampleData
  Chart1_settings.categoryAxis={dataField:"id", showGridLines:True}
  Chart1_settings.seriesGroups = [ _
    { _
    type: "column", _
    columnsGapPercent: 30, _
    seriesGapPercent: 0, _
          valueAxis: _
          { _
          minValue: 0, _
          maxValue: 50, _
          unitInterval: 10, _
