I try to change the background color (by using bgColor )of my chart but it doesn't work. Can you help me?
 
	My Code: 
 
	import React from "react"; 
	import FusionCharts from "fusioncharts"; 
	import TimeSeries from "fusioncharts/fusioncharts.timeseries"; 
	import ReactFC from "../lib/ReactFC";
 
	ReactFC.fcRoot(FusionCharts, TimeSeries);
 
	const jsonify = res => res.json(); 
	const dataFetch = fetch( 
	  "https://s3.eu-central-1.amazonaws.com/fusion.store/ft/data/dual-y-axis-data.json" 
	).then(jsonify); 
	const schemaFetch = fetch( 
	  "https://s3.eu-central-1.amazonaws.com/fusion.store/ft/schema/dual-y-axis-schema.json" 
	).then(jsonify);
 
	const dataSource = { 
	  chart: { 
	    multicanvas: false, 
	    bgColor: "#DDDDDD" 
	  }, 
	  caption: { 
	    text: "Energy & Temperature Measurements" 
	  }, 
	  yaxis: [ 
	    { 
	      plot: [ 
	        { 
	          value: "Energy", 
	          connectnulldata: true, 
	          type: "line" 
	        } 
	      ], 
	      format: { 
	        suffix: " kWh" 
	      } 
	    }, 
	    { 
	      plot: [ 
	        { 
	          value: "Temperature", 
	          connectnulldata: true, 
	          type: "line" 
	        } 
	      ], 
	      format: { 
	        suffix: " °C" 
	      } 
	    } 
	  ] 
	};
 
	class ChartViewer extends React.Component { 
	  constructor(props) { 
	    super(props); 
	    this.onFetchData = this.onFetchData.bind(this); 
	    this.state = { 
	      timeseriesDs: { 
	        type: "timeseries", 
	        renderAt: "container", 
	        width: "600", 
	        height: "400", 
	        dataSource 
	      } 
	    }; 
	  }
 
	  componentDidMount() { 
	    this.onFetchData(); 
	  }
 
	  onFetchData() { 
	    Promise.all([dataFetch, schemaFetch]).then(res => { 
	      const data = res[0]; 
	      const schema = res[1]; 
	      const fusionTable = new FusionCharts.DataStore().createDataTable( 
	        data, 
	        schema 
	      ); 
	      const timeseriesDs = Object.assign({}, this.state.timeseriesDs); 
	      timeseriesDs.dataSource.data = fusionTable; 
	      this.setState({ 
	        timeseriesDs 
	      }); 
	    }); 
	  }
 
	  render() { 
	    return ( 
	      <div> 
	        {this.state.timeseriesDs.dataSource.data ? ( 
	          <ReactFC {...this.state.timeseriesDs} /> 
	        ) : ( 
	          "loading" 
	        )} 
	      </div> 
	    ); 
	  } 
	}
