Echarts图表常用功能配置，Demo示例

先看下效果图：

就如上图所示，都是些常用的基本配置。 Legend分页，X轴设置，Y轴设置，底部缩放条设置， 数值显示样式设置，工具箱设置，自定义工具按钮， 绑定点击事件等等。这些配置代码中都做了简单的注释。下面看下代码，代码总共分为了3个js文件，分别如下：

1.    option.js

let option = {

    // 标题配置
    title: {
        text: '这是一个演示用例',
        textStyle: {
            color: '#666',  //标题字体颜色
            fontSize: 18    //标题字体大小
        },
        show: true,
        x: 'center'     //水平居中
    },

    // 画布边距设置
    grid: {
        left: '5%',
        right: '10%',
        bottom: '15%',
        containLabel: true
    },

    // 提示配置
    tooltip: {
        trigger: 'axis',
        axisPointer: {
            type: 'shadow'  // 阴影模式
        }
    },

    // 图例配置
    legend: {
        data: [

// 浏览器窗口大小改变时，图表自适应
window.addEventListener('resize', () => { demo.resize(); });

option.js 是echarts的配置项，单独一个配置对象。 demo.js是一个类，里面定义了一些方法用来操作图表，改变图表的一些样式和 行为。 index.js是实际页面调用的js文件，它引入了option.js 和 demo.js。因为用了webpack 进行打包，打包后的文件名为bundle.js，所以index.html文件只引用了一个bundle.js文件。

以上就是所有的代码了，用的ES6的语法。echarts 工具箱 (toolbox) 中的数据视图按钮点击后出现的数据视图我嫌弃它太丑了，所以重新写了样式。默认情况下它是一个可编辑的多行文本框，在option.js中重新拼成了table。 效果如下图：
