小程序引入Echarts
1.下载 GitHub 上的 ecomfe/echarts-for-weixin 项目
2.echarts下载,在线定制,选择图表,代码压缩
3.替换项目ec-canvas中的echarts.js
4.page.json引入
{
"usingComponents": {
"ec-canvas":"../../../../ec-canvas/ec-canvas"
}
}
5.js中引入
import * as echarts from "../../../../ec-canvas/echarts"
//初始化
init(arr){
this.lazyComponent.init((canvas,width,height,dpr)=>{
let chart=echarts.init(canvas,null,{
width:width,height:height,devicePixelRation:dpr
})
let option=this.getOption(arr)
chart.setOption(option)
this.chart=chart
return chart
})
},
getOption(arr){
return{
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [
{
data: arr,
type: 'bar'
}
]
}
}
//调用
this.lazyComponent=this.selectComponent("#myChart-dom")
this.init([120, 200, 150, 80, 70, 110, 130])
