angular11 引入echarts
1、项目下载echarts的npm包
项目根目录执行命令:
npm install echarts --save
下载成功后项目的package.json文件中的‘dependencies’对象下会自动添加‘echarts’,并标注你下载的版本
"dependencies": { "@angular/animations": "~11.2.1", "@angular/common": "~11.2.1", "@angular/compiler": "~11.2.1", "@angular/core": "~11.2.1", "@angular/forms": "~11.2.1", "@angular/platform-browser": "~11.2.1", "@angular/platform-browser-dynamic": "~11.2.1", "@angular/router": "~11.2.1", "echarts": "^5.3.2", "ng-zorro-antd": "^11.4.2", "rxjs": "~6.6.0", "tslib": "^2.0.0", "zone.js": "~0.11.3" },
2、下载成功后,在你需要绘制图表的组件的ts文件中导入echarts
import * as echarts from 'echarts';
具体使用demo如下:
ts:
import {AfterViewInit, Component, OnInit, ViewChild} from '@angular/core';
import * as echarts from 'echarts';
@Component({
selector: 'app-echart',
templateUrl: './echart.component.html',
styleUrls: ['./echart.component.less']
})
export class EchartComponent implements OnInit, AfterViewInit {
chart: any;
@ViewChild('chartTpl') chartTpl;
constructor() {
}
ngOnInit(): void {
}
ngAfterViewInit(): void {
// 需要等页面加载完成后才能获取页面元素
this.initChart();
}
/**
* 初始化图表
*/
initChart(): void {
this.chart = echarts.init(this.chartTpl.nativeElement);
/**
* 绑定resize
*/
window.addEventListener('resize', () => {
this.chart.resize();
});
this.chart.setOption({
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [
{
data: [120, 200, 150, 80, 70, 110, 130],
type: 'bar',
showBackground: true,
backgroundStyle: {
color: 'rgba(180, 180, 180, 0.2)'
}
}
]
});
}
}
html:
<div #chartTpl style="width: 600px;height: 300px"></div>
