Copy and paste the code below

var queryData      = [];
finstack.eval(this.dataQuery, function(data){
    var realPoints  = data.result.toObj(); 
    realPoints.forEach(function(p,index) {
        queryData.push({
            date   : p.ts,
            value  : p.v0.toFixed(1),
        });
    });

    if (event.chart.chartScrollbar.enabled === enabled)
      return;
    event.chart.chartScrollbar.enabled = enabled
    event.chart.validateNow(false, true);
