  options := map[string]interface{}{
      "series":  []interface{}{
          map[string]interface{}{

              "data": []int{},
          },

      },
  }
  highcharts.NewDynamicChart("/dynamic/", options, data)
  go func(){                                                                 
      for i := 0; i < 10; i++{                                               
          data<-i                                                            
          time.Sleep(i * 1e9)
