[Chartjs]-Use Chartjs with reactjs

✅

Not sure if this is helpful (not used react-faux-dom) but I do the following; render a canvas element using react then when the component mounts use that moment to create the graph

import React from 'react';
import Chart from 'chart.js';
import ReactDOM from 'react-dom';

class ChartComponent extends React.Component {


    componentDidMount() {
        this.initializeChart(this.props.config);
    }

    initializeChart(options) {
        let el = ReactDOM.findDOMNode(this.refs.chart);
        let ctx = el.getContext("2d");
        let chart = new Chart(ctx, options);
    }

    render() {
        return (<canvas ref="chart" height="400px" />);
    }

}

export default ChartComponent;

Also You can use React.createRef() from React16

class Chart extends Component {
  constructor(props) {
    super(props);

    this.chartRef = React.createRef();
  }

  componentDidMount() {
    const ctx = this.chartRef.current.getContext('2d');
    new ChartJS(ctx, options); // eslint-disable-line no-new
  }

  render() {
    return (
        <canvas ref={this.chartRef} />
      </div>
    );
  }
}

import React,{Component} from 'react';
import Chart from "chart.js";

class GraphChart extends Component {
    constructor(props) {
        super(props);
        this.myRef = React.createRef();

      }

      componentDidMount() {
        const ctx = this.ctx;

        new Chart(ctx, {
          type: "bar",
          data: {
            labels: ["Red", "Blue", "Yellow"],
            datasets: [
              {
                label: "# of Likes",
                data: [12, 19, 3],
                backgroundColor: [
                  "rgba(255, 99, 132, 0.2)",
                  "rgba(54, 162, 235, 0.2)",
                  "rgba(255, 206, 86, 0.2)"
                ]
              },
              {
                label: "# of Likes",
                data: [-12, -19, -3],
                backgroundColor: [
                  "rgba(255, 99, 132, 0.2)",
                  "rgba(54, 162, 235, 0.2)",
                  "rgba(255, 206, 86, 0.2)"
                ]
              }
            ]
          }
        });
      }

      render() {

        return (
            <div>
                <canvas width='800' height='300' ref={ctx => (this.ctx = ctx)}/>
            </div>
        )
    }
}
export default GraphChart;
