效果圖:兩跟狀態圖公用一個提示信息,在代碼塊中漸變效果被註釋了
- 定義一個可以供option 渲染的div
<div ref="myChart_production_efficient" :style="'width:100%;height:'+templateHeight+'px;'" id="myChart_production_efficient"></div>
2.定義 option ,將修改默認柱狀圖的樣式、將setEchart放入method中,頁面加載時執行, color: new this.$echarts.graphic.LinearGradient(0, 1, 0, 0,
[
{ offset: 0, color: '#01516E' },
{ offset: 0.5, color: '#188df0' },
{ offset: 1, color: '#008CEB' }
]
)這一行代碼如果單獨執行會報錯,要放在特點環境中,用於柱狀圖漸變效果
SetEchart () {
// 基於準備好的dom,初始化echarts實例
let myChart = this.$echarts.init(document.getElementById("myChart_production"), 'chalk');
// 繪製圖表
var option = {
title: {
text: '品牌當天生產效率', //主標題

color: '#01FCDE', //顏色
