前言

由于在项目中需要对数据进行可视化处理,也就是用图表展示,众所周知echarts是非常强大的插件。但是新手猛的上手的话,可能会有点束手无策,所以这篇就是来写一点入门的内容,外加自己一点的小心得。

一、首先要在项目中下载echarts依赖

?
1
2
3
npm install echarts -S
    //或者使用淘宝的镜像
cnpm install echarts -S

二、然后就要再main.js文件中来进行全局引入

?
1
2
3
4
// 引入echarts
import echarts from 'echarts'
 
Vue.prototype.$echarts = echarts

三、在Vue组件中设置一个div

?

7
<template>
    <div>
        <div class="body">
            <div id="echarts"></div> //就是这一行
        </div>
    </div>
</template>

四、去Echarts官网寻找想设置的实例图

再然后,根据找到的这个图里的数据及变量,来进行声明到data中。

data() {
            return {
                option: {
                    title: {
                        text: '堆叠区域图'
                    },
                    tooltip: {
                        trigger: 'axis',
                        axisPointer: {
                            type: 'cross',
                            label: {
                                backgroundColor: '#6a7985'
                            }
                        }
                    },
                    legend: {
                        data: ['邮件营销', '联盟广告', '视频广告', '直接访问', '搜索引擎']
                    },
                    grid: {
                        left: '3%',
                        right: '4%',
                        bottom: '3%',
                        containLabel: true
                    },
                    xAxis: [{
                        type: 'category',
                        boundaryGap: false,
                        data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
                    }],
                    yAxis: [{
                        type: 'value'
                    }],
                    series: [{
                            name: '邮件营销',
                            type: 'line',
                            stack: '总量',
                            areaStyle: {},
                            data: [120, 132, 101, 134, 90, 230, 210]
                        },
                        {
                            name: '联盟广告',
                            type: 'line',
                            stack: '总量',
                            areaStyle: {},
                            data: [220, 182, 191, 234, 290, 330, 310]
                        },
                        {
                            name: '视频广告',
                            type: 'line',
                            stack: '总量',
                            areaStyle: {},
                            data: [150, 232, 201, 154, 190, 330, 410]
                        },
                        {
                            name: '直接访问',
                            type: 'line',
                            stack: '总量',
                            areaStyle: {},
                            data: [320, 332, 301, 334, 390, 330, 320]
                        },
                        {
                            name: '搜索引擎',
                            type: 'line',
                            stack: '总量',
                            label: {
                                normal: {
                                    show: true,
                                    position: 'top'
                                }
                            },
                            areaStyle: {},
                            data: [820, 932, 901, 934, 1290, 1330, 1320]
                        }
                    ]
                }
            }
        }

五、在生命周期中挂载

?
1
2
3
4
5
mounted() {
            let myChart = this.$echarts.init(document.getElementById("echarts"));
            //设置echarts对象的option属性
            myChart.setOption(this.option)
        }

六、再在该div外面的盒子设置相关的css

?

<style scoped>
.body
    {
     width: 100%;
     height: 100vh;
     margin-left: 250px;
     margin-top: -280px;
    }
#echarts
    {
     width: 80%;
     height: 60%;
     border: 1px solid red;
    }
</style>
