    "type": "line",
  },
}

Dynamic Chart

When using a dynamic chart

package main

import (
  highcharts "github.com/Narsil/gohighcharts"
)

func main(){
  data := make(chan interface{})                                             
  options := map[string]interface{}{
      "series":  []interface{}{
          map[string]interface{}{
              "name": "Dynamic chart",
              "data": []int{},
          },
      },
      "chart": map[string]interface{}{
          "type": "line",
      },
  }
  highcharts.NewDynamicChart("/dynamic/", options, data)
  go func(){                                                                 
      for i := 0; i < 10; i++{                                               
          data<-i                                                            
          time.Sleep(i * 1e9)                                                      
      }                                                                      
  }()
}
