export default class HeatMap extends React.Component {
  render() {
    return (
      <ReactFusioncharts

        width="100%"
        height="100%"
        dataFormat="JSON"
        dataSource={dataSource}

    );
  }
}

Here i am using fusioncharts with react.

But i am getting below error in my console.

errors:

Uncaught SyntaxError: Unexpected token <
fusioncharts.js:2202 Uncaught (in promise) Error: Error: Loading chunk 4 failed.
(missing: http://localhost:3000/fusioncharts.powercharts.js)
    at HTMLScriptElement.a (fusioncharts.js:103)
    at fusioncharts.js:2202

Do i need to install powercharts or treemaps separately for this.

PLease have a look

I checked with fusionchart team they are saying

Please note in order to render treemap chart you need to import fusioncharts.js, then fusioncharts.powercharts.js after that you need to include fusioncharts.treemap.js In order to render heatmap chart you need to import fusioncharts.js, then fusioncharts.powercharts.js ​

where i need to import not ale to understand

回答1:

As per fusioncharts doc for react.

https://www.fusioncharts.com/dev/getting-started/react/your-first-chart-using-react

End of the Render the chart section. You can see the specific imports for specific chart types.

I hope it will help you.

回答2:

In order to render the drag node chart, you need to import the following in the app.js

import FusionCharts from 'fusioncharts';
import PowerCharts from 'fusioncharts/fusioncharts.powercharts';
import FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';
import ReactFC from 'react-fusioncharts';

ReactFC.fcRoot(FusionCharts, PowerCharts, FusionTheme);

In order to render the treemap chart, you need to import the following

import FusionCharts from 'fusioncharts';
import PowerCharts from 'fusioncharts/fusioncharts.powercharts';
import TreeMap from 'fusioncharts/fusioncharts.treemap';
import FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';
import ReactFC from 'react-fusioncharts';

ReactFC.fcRoot(FusionCharts, PowerCharts ,TreeMap,FusionTheme);
