提前10天把中烟活动做完了，以为能打酱油到除夕那天，结果又要做什么数据看板，方便烟草领导过年查看数据，还只给5天时间，真实压榨剥削啊，下辈子再也不‘拍黄片’了，不！下份工作我就转前端了，php我再也不写了。
1.安装echarts 依赖 npm install echarts
2.引用 import * as echarts from ‘echarts’;
3.上代码
<canvas :style="{
width: '100%', height: '500rpx'}" id="mychart" canvas-id="mychart"
:canvas-type="canvasType"></canvas>
chart() {
const ctx = document.getElementById('mychart');
const chart = echarts.init(ctx);
chart.setOption({
grid: {
// 设置图表距离顶部,左侧，右侧和底部的高度
top: '50rpx',
left: '50rpx',
right: '50rpx',
bottom: '50rpx',
},
color: ["#2363FF", "#03C6D4", "#6B49F5"],
title: {
left: "center",
text: this.ChartDatatext,
},
tooltip: {
width: '100%',
trigger: 'axis',
axisPointer: {
type: 'cross',
crossStyle: {
color: '#999'
}
}
},
legend: {
bottom: 0,
itemWidth: 15,
itemHeight: 8,
itemGap: 40,
data: ['小盒扫码数', '条盒扫码数', '总扫码数']
},
xAxis: [{
type: 'category',
data: this.tongdate,
axisPointer: {
type: 'shadow'
}
}],
yAxis: [{
type: 'value',
name: '',
min: 0,
//max: 0,
max: function(value) {
return Math.ceil(value.max * 1.2);
},
interval: 1000,
axisLabel: {
formatter: '{value}'
}
},
],
series: [{
name: '小盒扫码数',
type: 'bar',
data: this.box
},
{
name: '条盒扫码数',
type: 'bar',
data: this.bar
},
{
name: '总扫码数',
type: 'line',
data: this.all
}
]
})
},
