Question

设置 react-chartjs 时出现此错误，我使用的是here 示例。这是我得到的错误：

Uncaught (in promise) TypeError: Cannot read property 'xLabels' of undefined
    at updatePoints (core.js:127)
    at Object.classData.componentWillReceiveProps (core.js:48)
    ...... so on

在this post他们说他们已经修好了，但他们没有想到。

这是我的代码：

var Chart = require('chart.js');
var LineChart = require("react-chartjs").Line;
export default class Dashboard extends Component {
    constructor(props){
    super(props);
    var result = '';
    this.state = {
       chartData: '',
       chartOptions: ''
    };

  }

  componentDidMount(){
    var chartData =  {
        labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
        datasets: [{
            label: '# of Votes',
            data: [12, 19, 3, 5, 2, 3],
            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(54, 162, 235, 0.2)',
                'rgba(255, 206, 86, 0.2)',
                'rgba(75, 192, 192, 0.2)',
                'rgba(153, 102, 255, 0.2)',
                'rgba(255, 159, 64, 0.2)'
            ],
            borderColor: [
                'rgba(255,99,132,1)',
                'rgba(54, 162, 235, 1)',
                'rgba(255, 206, 86, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(153, 102, 255, 1)',
                'rgba(255, 159, 64, 1)'
            ],
            borderWidth: 1
        }]
    }
    var chartOptions = {
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero:true
                }
            }]
        }
    }
    this.setState({
      chartData: chartData,
      chartOptions: chartOptions
    })
  }

  render () {

    return (
      <div className="container">
        <div className="chart-wrapper">  
          <LineChart data={this.state.chartData} width="600" height="250"/>
        </div>
      </div>
    )
  }
}

可能是什么问题？我是新来的反应和坚持图表。任何帮助，将不胜感激。

＆＃34;的重绘＆＃34;应该有所帮助：

<LineChart data={this.state.chartData} width="600" height="250" redraw/>

react-chartjs集成错误。无法读取未定义的属性'xLabels'
