先看下效果圖:
就如上圖所示,都是些常用的基本配置。 Legend分頁,X軸設置,Y軸設置,底部縮放條設置, 數值顯示樣式設置,工具箱設置,自定義工具按鈕, 綁定點擊事件等等。這些配置代碼中都做了簡單的註釋。下面看下代碼,代碼總共分為了3個js文件,分別如下:
1. option.js
let option = { // 標題配置 title: { text: ‘這是一個演示用例‘, textStyle: { color:‘#666‘, //標題字體顏色 fontSize: 18 //標題字體大小 }, show: true, x: ‘center‘ //水平居中 }, // 畫布邊距設置 grid: { left: ‘5%‘, right: ‘10%‘, bottom: ‘15%‘, containLabel: true }, // 提示配置 tooltip: { trigger: ‘axis‘, axisPointer: { type:‘shadow‘ // 陰影模式 } }, // 圖例配置 legend: { data: [ ‘出貨量‘, ‘進貨量‘, ‘售出量‘, ‘測試一‘, ‘測試二‘, ‘測試三‘, ‘測試四‘, ‘測試五‘, ‘測試六‘, ‘測試七‘, ‘測試八‘, ‘測試九‘, ‘測試十‘, ‘復試一‘, ‘復試二‘, ‘復試三‘, ‘復試四‘, ‘復試五‘, ‘復試六‘, ‘復試七‘, ‘復試八‘, ‘復試九‘, ‘復試十‘, ‘補位一‘, ‘補位二‘, ‘補位三‘, ‘補位四‘, ‘補位五‘, ‘補位六‘, ‘補位七‘ ], selected: {‘出貨量‘: true, ‘進貨量‘: true, ‘售出量‘: true, ‘測試一‘: false, ‘測試二‘: false, ‘測試三‘: false, ‘測試四‘: false, ‘測試五‘: true, ‘測試六‘: false, ‘測試七‘: false, ‘測試八‘: false, ‘測試九‘: false, ‘測試十‘: false, ‘復試一‘: false, ‘復試二‘: true, ‘復試三‘: false, ‘復試四‘: false, ‘復試五‘: false, ‘復試六‘: false, ‘復試七‘: false, ‘復試八‘: false, ‘復試九‘: false, ‘復試十‘: false, ‘補位一‘: false, ‘補位二‘: false, ‘補位三‘: false, ‘補位四‘: false, ‘補位五‘: false, ‘補位六‘: false, ‘補位七‘: false }, show: true, type: ‘scroll‘, //啟用翻頁模式 orient: ‘vertical‘, //縱向顯示 right: 15, top: 45, backgroundColor: ‘#eee‘, padding: 10 }, // 工具箱配置 toolbox: { feature: { // 自定義工具按鈕,註:自定義按鈕必須以 my 開頭 myTool: { show: true, title: ‘自定義擴展方法‘, icon: ‘image://http://echarts.baidu.com/images/favicon.png‘, //註: image:// 這個是固定格式,後面跟圖片地址 onclick: () => { alert(‘您剛剛點擊了自定義工具按鈕!‘);

2. demo.js
// 示例圖-操作類 export default class Demo { // 構造函數 constructor(option, echarts) { this.option = option; this.echarts = echarts; } // 初始化圖表 init() { this.echarts.setOption(this.option, true); } // X軸坐標文字旋轉角度 xTextRotate(deg) { this.option.xAxis.axisLabel.rotate = parseInt(deg, 10); this.init(); } // 系列數值的顯示位置 seriesLabelPosition(position) { let series = this.option.series; let newSeries = series.map((item) => { item.label.position = position; return item; }); this.option.series = newSeries; this.init(); } // 系列數值是否顯示 seriesLabelDisplay(mark) { let series = this.option.series; let newSeries = series.map((item) => { item.label.show = mark; return item; }); this.option.series = newSeries; this.init(); } // 系列數值 % seriesLabelWithPercent(mark) { let series = this.option.series; let newSeries = series.map((item) => { item.label.formatter = mark ? ‘{c}%‘ : ‘{c}‘; return item; }); this.option.series = newSeries; this.init(); } // 系列數值旋轉 seriesLabelRotate(deg) { let series = this.option.series; let newSeries = series.map((item) => { item.label.rotate = parseInt(deg, 10); return item; }); this.option.series = newSeries; this.init(); } // 底部拖動條是否顯示 dataZoomDisplay(mark) { if(mark) { this.option.dataZoom[0].show = true; this.option.dataZoom[0].end = 50; } else { this.option.dataZoom[0].show = false; this.option.dataZoom[0].end = 100; } this.init(); } // 提示模式 tooltipModel(model) { this.option.tooltip.axisPointer.type = model; this.init(); } // Y軸線條 yLineStyle(style) { if(style === ‘none‘) { this.option.yAxis.axisLine.show = false; } else { this.option.yAxis.axisLine.show = true; this.option.yAxis.axisLine.lineStyle.type = style; } this.init(); } // Y軸分割線 ySplitLineStyle(style) { if(style === ‘none‘) { this.option.yAxis.splitLine.show = false; } else { this.option.yAxis.splitLine.show = true; this.option.yAxis.splitLine.lineStyle.type = style; } this.init(); } // 綁定事件 bindEvent(eventName, eventAction) { this.echarts.on(eventName, eventAction); } // 自適應調整 resize() { this.echarts.resize(); } }
3. index.js
import echarts from ‘echarts‘; import option from ‘./option‘; import Demo from ‘./demo‘; // 根據id獲取元素 let $ = id => document.getElementById(id); // 初始化圖表 let demo = new Demo(option, echarts.init($(‘echarts‘))); demo.init(); // 是否顯示數值 $(‘sel1‘).addEventListener(‘change‘, (e) => { demo.seriesLabelDisplay(e.target.value === ‘1‘); }); // 數值顯示位置 $(‘sel2‘).addEventListener(‘change‘, (e) => { demo.seriesLabelPosition(e.target.value); }); // 數值 % $(‘sel3‘).addEventListener(‘change‘, (e) => { demo.seriesLabelWithPercent(e.target.value === ‘1‘); }); // X軸文字旋轉角度 $(‘sel4‘).addEventListener(‘change‘, (e) => { demo.xTextRotate(e.target.value); }); // 底部拖動條是否顯示 $(‘sel5‘).addEventListener(‘change‘, (e) => { demo.dataZoomDisplay(e.target.value === ‘1‘); }); // 設置提示模式 $(‘sel6‘).addEventListener(‘change‘, (e) => { demo.tooltipModel(e.target.value); }); // Y軸線條 $(‘sel7‘).addEventListener(‘change‘, (e) => { demo.yLineStyle(e.target.value); }); // 數值旋轉 $(‘sel8‘).addEventListener(‘change‘, (e) => { demo.seriesLabelRotate(e.target.value); }); // Y軸分割線 $(‘sel9‘).addEventListener(‘change‘, (e) => { demo.ySplitLineStyle(e.target.value); }); // 綁定點擊事件 demo.bindEvent(‘click‘, (param) => { alert(`${param.name} - ${param.seriesName} - ${param.data}`); }); // 瀏覽器窗口大小改變時,圖表自適應 window.addEventListener(‘resize‘, () => { demo.resize(); });
option.js 是echarts的配置項,單獨一個配置對象。 demo.js是一個類,裏面定義了一些方法用來操作圖表,改變圖表的一些樣式和 行為。 index.js是實際頁面調用的js文件,它引入了option.js 和 demo.js。因為用了webpack 進行打包,打包後的文件名為bundle.js,所以index.html文件只引用了一個bundle.js文件。
index.html

以上就是所有的代碼了,用的ES6的語法。echarts 工具箱 (toolbox) 中的數據視圖按鈕點擊後出現的數據視圖我嫌棄它太醜了,所以重新寫了樣式。默認情況下它是一個可編輯的多行文本框,在option.js中重新拼成了table。 效果如下圖:
