Example shows React Multi Series Line Chart with default line color based on the selected theme.
import React, { Component } from 'react'; import CanvasJSReact from '@canvasjs/react-charts'; //let CanvasJSReact = require('@canvasjs/react-charts'); let CanvasJS = CanvasJSReact.CanvasJS; let CanvasJSChart = CanvasJSReact.CanvasJSChart; class App extends Component { render() { const options = { animationEnabled: true, theme: "light2", title: { text: "New York Climate" }, axisX: { valueFormatString: "MMM", intervalType: "month", interval: 1 }, axisY: { title: "Temperature", suffix: "°F" }, toolTip: { shared: true }, legend: { cursor: "pointer", itemclick: function (e) { if (typeof (e.dataSeries.visible) === "undefined" || e.dataSeries.visible) { e.dataSeries.visible = false; } else { e.dataSeries.visible = true; } e.chart.render(); } }, data: [{ type: "line", name: "Minimum", showInLegend: true, yValueFormatString: "#,###°F", dataPoints: [ { x: new Date(2021, 0, 1), y: 27 }, { x: new Date(2021, 1, 1), y: 28 }, { x: new Date(2021, 2, 1), y: 35 }, { x: new Date(2021, 3, 1), y: 45 }, { x: new Date(2021, 4, 1), y: 54 }, { x: new Date(2021, 5, 1), y: 64 }, { x: new Date(2021, 6, 1), y: 69 }, { x: new Date(2021, 7, 1), y: 68 }, { x: new Date(2021, 8, 1), y: 61 }, { x: new Date(2021, 9, 1), y: 50 }, { x: new Date(2021, 10, 1), y: 41 }, { x: new Date(2021, 11, 1), y: 33 } ] }, { type: "line", name: "Maximum", showInLegend: true, yValueFormatString: "#,###°F", dataPoints: [ { x: new Date(2021, 0, 1), y: 40 }, { x: new Date(2021, 1, 1), y: 42 }, { x: new Date(2021, 2, 1), y: 50 }, { x: new Date(2021, 3, 1), y: 62 }, { x: new Date(2021, 4, 1), y: 72 }, { x: new Date(2021, 5, 1), y: 80 }, { x: new Date(2021, 6, 1), y: 85 }, { x: new Date(2021, 7, 1), y: 84 }, { x: new Date(2021, 8, 1), y: 76 }, { x: new Date(2021, 9, 1), y: 64 }, { x: new Date(2021, 10, 1), y: 54 }, { x: new Date(2021, 11, 1), y: 44 } ] }] }; 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*/} </div> ); } } export default App;
In the above example, legends are enabled by setting the showInLegend property to true. You can also customize the look & feel of line by adjusting its color and thickness by setting lineColor & lineThickness properties.
