How to add Data label to a series

[Root Fsociety]

I made a google Apps script to modify a chart and I would like to display the data label of the series number 0 but the line .setOption('series',{ 1:{color: '#2ecc71'}}) (where I change the color of the series 1) remove the data label of the series 0.

 

      var Vmax =1.1*ss.getRangeByName("D285").getValue(); //get max and min here (before, it's equal to 0)
      var Vmin =0.9*ss.getRangeByName("C285").getValue(); 
      var sheet = SpreadsheetApp.getActiveSheet();
      var chart = sheet.getCharts()[46];
      chart = chart.modify()
        .setChartType(Charts.ChartType.AREA)
        .setOption('title',string)
        .setOption('vAxes', {0: {textStyle: {fontSize: 10}, titleTextStyle: {fontSize : 8}, viewWindow: {min: Vmin, max:Vmax}}})
        .setOption('series',{ 1:{color: '#2ecc71'}})
        .setOption('titleTextStyle',{alignment:"center"})
        .setOption('animation.startup',true)
        .setOption('animation.duration', 5000)
        .setOption('hAxis.slantedText',true)
        .setPosition(290,6,0,0)
        .build();
        Logger.log(Vmax);
        Logger.log(Vmin);
      sheet.updateChart(chart);
