我正在使用 react-highcharts。除了 nodata 状态外，它工作得很好。当图表有空数据时，我需要显示“无可用数据”消息。

我检查了官方 highcharts 的 no-data-to-display.js，但它不适用于 React。我想做这样的结果：http: //jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/no-data-to-显示/无数据饼图/

import React from 'react';
import Highcharts from 'react-highcharts/dist/bundle/highcharts';
require('highcharts-no-data-to-display');

class MyChart extends React.Component {
    constructor(props) {
        super();
        this.state = this._getInitialState(props);
    }
    static chartColors() {
        return [
        '#04a5af', '#4a6cb4', '#2d4665', '#76b5db', '#b4dcee','#cae9de','#24a9b2','#48d0ae','#2a2b32', '#5065ae'
        ]
    }

    componentWillReceiveProps(newProps) {
        this.setState(this._getInitialState(newProps));
    }

    _getInitialState(props) {
        return {
            chartConfig:
            {
                colors: MyChart.chartColors(),

    }



    render() {


        return (
            <div refs="wa-chart">
                <Highcharts config={this.state.chartConfig} ref="chart" isPureConfig={true} />
            </div>);
    }
}



export default MyChart;

我使用的是react0.13.3、3.0.0react-highcharts版和highcharts-no-data-to-display0.1.2 版

你的导入应该是这样的。

import Highcharts from 'highcharts';
import NoDataToDisplay from 'highcharts/modules/no-data-to-display';
import HighchartsReact from 'highcharts-react-official';

NoDataToDisplay(Highcharts);

定义您的选项以获取 noData 消息。

const options = {
lang: {
      noData: props.noDataMessage,
    },
    noData: {
      style: {
        fontWeight: 'bold',
        fontSize: '15px',
        color: '#303030',
      },
    },
};

在您的 highcharts 中使用此选项。

<HighchartsReact
   highcharts={Highcharts}
   options={options}
/>

https://github.com/kirjs/react-highcharts
提示：使用 highcharts 模块/附加组件，如导出、数据等（演示）

例如：

import React from 'react';
import Highcharts from 'react-highcharts/dist/bundle/highcharts';
require('highcharts-no-data-to-display')(ReactHighcharts.Highcharts)

class MyChart extends React.Component {
    constructor(props) {
        super();
        this.state = this._getInitialState(props);
    }
    static chartColors() {
        return [
        '#04a5af', '#4a6cb4', '#2d4665', '#76b5db', '#b4dcee','#cae9de','#24a9b2','#48d0ae','#2a2b32', '#5065ae'
        ]
    }

    componentWillReceiveProps(newProps) {
        this.setState(this._getInitialState(newProps));
    }

    _getInitialState(props) {
        return {
            chartConfig:
            {
                colors: MyChart.chartColors(),

更新：我为此创建了一个 npm 包，只需安装它并使用它！这个-> react-highcharts-no-data-to-display

ANSWER: 你要做的就是添加(ReactHighcharts.Highcharts)nextrequire('highcharts-no-data-to-display')很容易吧？

以防万一，如果有人遇到同样的问题（尝试在 React-HighCharts 中添加“无数据”消息）。步骤是：

  1. 安装它！在终端运行中：npm install highcharts-no-data-to-display --save
  2. 在具有要添加无数据消息的图表的反应文件中，您必须require('highcharts-no-data-to-display')(ReactHighcharts.Highcharts)在第一行添加
  3. 此外，如果您想自定义消息的文本和位置。添加这个：

>

lang:{
            noData: 'no data!' //the text to be displayed
          },
          noData: {
                  position: {
                      "x": 0, 
                      "y": 0,
                      "align": "center",
                      "verticalAlign": "middle"
                  }
          }

@ittus 所要求的完整代码应该是

import React from 'react';
import Highcharts from 'react-highcharts/dist/bundle/highcharts';
require('highcharts-no-data-to-display')(Highcharts.Highcharts)

class MyChart extends React.Component {
    constructor(props) {
        super();
        this.state = this._getInitialState(props);
    }
    static chartColors() {
        return [
        '#04a5af', '#4a6cb4', '#2d4665', '#76b5db', '#b4dcee','#cae9de','#24a9b2','#48d0ae','#2a2b32', '#5065ae'
        ]
    }

    componentWillReceiveProps(newProps) {
        this.setState(this._getInitialState(newProps));
    }

    _getInitialState(props) {
        return {
            chartConfig:
