3. echarts 具体讲解

3.1 配置项讲解

全部的配置项网址

https://echarts.apache.org/zh/option.html#title

配置名	作用
title	设置图表的标题
tooltip	图表提示框组件
trigger	触发方式
legend	图例组件
grid	网格配置，图表不一样和容器一样大。可以控制线性图的大小
toolbox	工具箱
xAxis	X 轴
yAxis	Y 轴
series	系列图表配置，显示那种配置信息，其中type 信息决定了图的类型，pie 为饼图，line 折线图，bar 为柱状图
color	设置线条颜色，是数组

3.2 柱状图

引入相关js

// ()(); 这个是立即执行函数
(function() {
    var myCharts = echarts.init(document.querySelector(".bar .chart"));

    // 制定数据
    var option = {
        // 设置图表的信息
        color: ["#2f89cf"],
        tooltip: {
            // 这个是提示框信息
            trigger: "axis",
            // 坐标轴触发，主要在柱状图，折线图等会使用类目轴的图表中使用。
            axisPointer: {
                // 坐标轴指示器，坐标轴触发有效
                type: "shadow", // 默认为直线，可选为：'line' | 'shadow'
            },
        },
        // 修改图表的大小
        grid: {
            left: "0%",
            top: "10px",

        }, ],
        yAxis: [{

                },
            },

            splitLine: {

                },
            },
        }, ],
        series: [{
            name: "直接访问",
            type: "bar",
            // 修改柱子的宽度
