import CanvasJSReact from '@canvasjs/react-charts';
//var CanvasJSReact = require('@canvasjs/react-charts');
var CanvasJS = CanvasJSReact.CanvasJS;
var CanvasJSChart = CanvasJSReact.CanvasJSChart;
class App extends Component {

const options = {
theme: "light2",
animationEnabled: true,
exportEnabled: true,

return (
<div>
<CanvasJSChart options = {options}
/* onRef={ref => this.chart = ref} */
/>
{/*You can get reference to the chart instance as shown above using onRef. This allows you to access all chart properties and methods*/}
