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 = {

3. index.js

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。

            <option value="dashed">Y軸分割線:虛線 dashed</option>
            <option value="dotted">Y軸分割線:虛線 dotted</option>
        </select>
    </div>
    <script src="bundle.js"></script>
</body>

</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:
