vue 中echarts的使用
在项目项目中,需要用到图表echarts,在这就不做解释了,只是把项目中用到的echarts记录一下
echarts官方地址: https://www.echartsjs.com/zh/index.html
echarts w3c文档: https://www.w3cschool.cn/echarts_tutorial/
vue-echarts: https://v-charts.js.org/#/
在这提一下,按需加载:
// 引入 ECharts 主模块
const echarts = require('echarts/lib/echarts')
require('echarts/lib/chart/line')
// 引入提示框和标题组件
require('echarts/lib/component/tooltip')
require('echarts/lib/component/title')
require('echarts/lib/component/legend')1.折线图,包含面的渐变
series: [{
name: this.legendData[0],
type: 'line',
// smooth: true,
symbol: 'circle',
symbolSize: 1,
// showSymbol: false,
lineStyle: {
normal: {
width: 0
}
},
// itemStyle 下的areaStyle实现面的渐变
itemStyle: {
normal: {
color: 'rgb(239,69,125)',
areaStyle : {
type : 'default',
color : new echarts.graphic.LinearGradient(0, 0, 1, 0,
[ {
offset : 0,
color : '#2BF4A3'
}, {
offset : 0.5,
color : '#14EED4'
}, {
offset : 1,
color : '#01E8FE'
} ]),
}
}
},
areaStyle: {
},
data: dealed,
label: {
show: true,
color: '#fff',
formatter: (params) => {
return params.value === allData[0] ? params.value : ''
}
}
}]图例: 
2.折线图,线的渐变
itemStyle: {
normal: {
color: 'rgb(239,69,125)',
areaStyle : {
type : 'default',
color : new echarts.graphic.LinearGradient(0, 0, 0, 1,
[ {
offset : 0,
color : 'rgba(255,89,87,1)'
}, {
offset : 0.5,
color : 'rgba(255,89,87,0.5)'
}, {
offset : 1,
color : 'rgba(255,89,87,0)'
} ]),
},
// itemStyle 下的lineStyle实现线的渐变
lineStyle: {
width: 2,
type: 'solid',
color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{
offset: 0,
color: '#f63138'
}, {
offset: 1,
color: '#fff'
}]),//线条渐变色
}
}
},图例:
3.地图,以百度地图为例
需要引入
// 引入 ECharts 主模块
const echarts = require('echarts/lib/echarts')
const map = new BMap.Map('allmap')
require('echarts/map/js/china')
// require('echarts/lib/chart/scatter')
require('echarts/lib/chart/effectScatter')
require('echarts/extension/bmap/bmap')
// 引入提示框和标题组件
require('echarts/lib/component/tooltip')
require('echarts/lib/component/title')
require('echarts/lib/component/legend')
export default {

props: {

},

7,3D地球
这个需要安装echarts-gl依赖,至于图片来源,可以去官方demo中下载
推荐一个demo: https://gallery.echartsjs.com/editor.html?c=xzDlVCoY7

总结,目前为止项目中就使用了这些,主要是实现3D地球和地图的时候遇到很多引入类的问题,基本都已经解决,在这做一个记录,不喜勿喷.
