[Solved]-Chart.js with React-Chart.js

React Chartjs has a dependency on Chart.js too. Install it like

npm install --save chart.js@^1.1.1 react react-dom

Also since Line is a named export you need to import it as

import {Line as LineChart} from 'react-chartjs';

Also make sure your chartData is an object like

{
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [
        {
            label: "My First dataset",
            fill: false,
            pointHoverRadius: 5,
            pointRadius: 1,
            pointHitRadius: 10,
            data: [65, 59, 80, 81, 56, 55, 40],
            spanGaps: false,
        }
    ]
};
