内容图文
1.首先下载echart依赖
npm install echarts --save
备注:npm 安装报错时使用cnpm
2.全局注册 在main.js里引入echart并在vue中注册echart
// 引入echarts
import echarts from ‘echarts‘;
Vue.prototype.$echarts = echarts;
3.在所使用模块 直接使用$echarts
<script>
methods:{
//绘制线性图
drawLine(id, titleName, gridData, yAxisName, legendData, xAxisData, seriesData) {
this.charts =this.$echarts.init(document.getElementById(id));
this.charts.setOption({
title: {
text: titleName,
x: ‘center‘
},
tooltip: {
trigger: ‘axis‘
},
legend: {
bottom: ‘5px‘,
data: legendData,
},
grid: {
left: ‘3%‘,
right: ‘4%‘,
bottom: gridData,
top: ‘60px‘,
containLabel: true
},
xAxis: {
type: ‘category‘,
boundaryGap: false,
data: xAxisData,
},
yAxis: {
type: ‘value‘,
name: yAxisName,
},
series: seriesData
})
}
},
//调用
mounted(){
this.$nextTick(function() {
this.drawLine(‘lineChart‘, this.lineChartTitle, ‘60px‘, this.lineChartYAxisName,
this.lineChartLegendData, this.lineChartXAxisData,
this.lineChartSeriesData);
});
}
</script>
4.不在main,js引用直接在所使用模块引用
// 在所用模块引入echarts
import echarts from ‘echarts‘;
此时定义echarts时需要将
this.charts =this.$echarts.init(document.getElementById(id)); 中的this.$echarts换成echarts
this.charts = echarts.init(document.getElementById(id));
具体代码如下
<style scoped>
.searchBtn {
width: 100%;
text-align: left;
background: #fbfbfb;
border: none;
border-bottom: 1px solid #eee;
}
.describe {
display: inline-block;
font-weight: bold;
padding: 15px 10px;
}
.changeTab {
color: #10a5f8;
}
.chartBoxs {
width: 100%;
height: 2rem;
margin-top: 10px;
}
</style>
