显示无数据可在 React Native 中显示的融合图表

Question

I am doing react native application. In that, I am trying to showing bar chart. So, I am using Fusion Chart , It is mandatory to use this library in my application. So, I followed this library installation and it was successful. But, Data is not showing at all.

No Data to display showing in screen.

My code is

export default class App extends Component {
  constructor(props) {
    super(props);

    this.state = {
      type: 'bar2d',
      width: '100%',
      height: '100%',
      dataFormat: 'json',
      dataSource: {
        chart: {
            captionFontSize: '16',
            subcaptionFontSize: '14',
            showAlternatevGridColor: '0',
            numDivLines: '0',
            valueFontColor: '#ffffff',
            yAxisMinValue: '0',
            yAxisMaxValue: '100',
            showYAxisValues: '0',
            // "canvasBorderColor" : "#b3ffb3",
            canvasBgColor: '#ffffff,#e6eeff',
            canvasTopMargin: '100',
            paletteColors: '#990000',
            usePlotGradientColor: '1',
            plotGradientColor: '#ff8080',
            divLineAlpha: '0',
            plotSpacePercent: '60',
            useDataPlotColorForLabels: '1',
            showPercentInTooltip: '0',
            showLegend: '1',
            showLabels: '0',
            showValues: '0',
            placeValuesInside: '1',
            showBorder: '0'
          },
          data: [
            {
              label: 'Travel & Leisure',
              value: '41'
            },
            {
              label: 'Advertising/Marketing/PR',
              value: '39'
            },
            {
              label: 'Other',
              value: '38'
            },
            {
              label: 'Real Estate',
              value: '32'
            },
          ],
          annotations: {
            showBelow: '0',
            autoScale: '1',
            groups: [{
              id: 'user-images',
              items: [{
                id: 'dyn-label-bg',
                color: '#000000',
                align: 'left',
                type: 'text',
                text: 'Best when calm',
                x: '$canvasStartX+0',
                y: '$dataset.0.set.0.ENDY-0'
              }, {
                id: 'dyn-label-bg',
                color: '#000000',
                align: 'left',
                type: 'text',
                text: 'Very Relaxed',
                x: '$canvasStartX+00',
                y: '$dataset.0.set.1.ENDY-0'
              }, {
                id: 'dyn-label-bg',
                color: '#000000',
                align: 'left',
                type: 'text',
                text: 'Mellow',
                x: '$canvasStartX+00',
                y: '$dataset.0.set.2.ENDY-0'
              }, {
                id: 'dyn-label-bg',
                color: '#000000',
                align: 'left',
                type: 'text',
                text: 'Out of Control',
                x: '$canvasStartX+00',
                y: '$dataset.0.set.3.ENDY-0'
              }]
            }]
          }
    }

    };

    this.libraryPath = Platform.select({
      // Specify fusioncharts.html file location
      ios: require('./assets/fusioncharts.html'),
      //android: { uri: 'file:///android_asset/fusioncharts.html' },
    });
  }

  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.heading}>
          FusionCharts Integration with React Native
        </Text>
        <View style={styles.chartContainer}>
          <FusionCharts
            type={this.state.type}
            width={this.state.width}
            height={this.state.height}
            dataFormat={this.state.dataFormat}
            dataSource={this.state.dataSource}
            libraryPath={this.libraryPath} // set the libraryPath property
          />
        </View>
      </View>
    );
  }
}

I have customised this for design. Can anyone tell me, Where I am doing wrong?

确保您有正确的 fusioncharts.html 路径，并在 script 标签中的 package.js 下运行此命令 "build:assets": "fc-build-assets --fc-template ./src/assets/fusioncharts-tpl.html ”
