Your state data is not defined as an array. Correct it as:

getInitialState:function () {

  return{
      default:10,
      data: [],
      color:'#58FA58'

  }
}

Add 

getInitialState: function() {
     return{
      default:10,
      data:[],
      color:'#58FA58'

  }
}

set data:[ ] in

getInitialState:function () {
      return{
          default:10,
          data:[],
          color:'#58FA58'

      }
    },

and check

componentDidMount:function () {
    api.getemail(this.state.default).then(function (response) {

    console.log('CHECK',response) //   <----------------

       this.setState({
           data:response

       })
    }.bind(this))
},
