1、官方网站
https://www.echartsjs.com/zh/index.html
2、angular中单引入echarts
（1）命令：npm i echarts
（2）在angular.json的scripts中引入echarts.js："./node_modules/echarts/dist/echarts.js"
（3）html中：
|
<div style="width: 700px;height: 400px;" nz-col #myechart>
</div>
|
（4）ts中：
|
import { Component, ViewChild, ElementRef, OnInit } from '@angular/core';
declare var echarts: any;
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
title = 'my-app';
@ViewChild('myechart') myechart: ElementRef;
EC1;
constructor(){}
ngOnInit(){
}
ngAfterViewInit() {
const option = {
title: {
text: '折线图堆叠'
},
tooltip: {
trigger: 'axis'
},
legend: {
data: ['邮件营销', '联盟广告', '视频广告', '直接访问', '搜索引擎']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
toolbox: {
feature: {
saveAsImage: {}
}
},
xAxis: {
type: 'category',
boundaryGap: false,
data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
},
yAxis: {
type: 'value'
},
series: [
{
name: '邮件营销',
type: 'line',
stack: '总量',
data: [120, 132, 101, 134, 90, 230, 210]
},
{
name: '联盟广告',
type: 'line',
stack: '总量',
data: [220, 182, 191, 234, 290, 330, 310]
},
{
name: '视频广告',
type: 'line',
stack: '总量',
data: [150, 232, 201, 154, 190, 330, 410]
},
{
name: '直接访问',
type: 'line',
stack: '总量',
data: [320, 332, 301, 334, 390, 330, 320]
},
{
name: '搜索引擎',
type: 'line',
stack: '总量',
data: [820, 932, 901, 934, 1290, 1330, 1320]
}
]
};
this.EC1 = echarts.init(this.myechart.nativeElement);
this.EC1.setOption(option, true);
}
}
|
|
<div id="statisticsChart" style="width: 100%; height: 100%;"></div>
declare var echarts;
chart;
drawEcharts() {
const option = {
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'shadow'
}
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis: [
{
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
axisTick: {
alignWithLabel: true
}
}
],
yAxis: [
{
type: 'value'
}
],
series: [
{
name: 'Direct',
type: 'bar',
barWidth: '60%',
color: '#0096E0',
data: [10, 52, 200, 334, 390, 330, 220]
}
]
};
this.chart = echarts.init(document.getElementById('statisticsChart'));
this.chart.setOption(option);
}
ngAfterViewInit(): void {
this.drawEcharts()
}
|
注：div需设置宽高；
echarts图放在ngAfterViewInit中
3、angular中使用ngx-echarts
（1） 命令：npm install echarts --save
npm install ngx-echarts --save
（2）在angular.json的scripts中引入echarts.js："./node_modules/echarts/dist/echarts.js"
（3）在跟模块中导入NgxEchartsModule
|
import {NgxEchartsModule} from 'ngx-echarts'; imports: [
NgxEchartsModule
],
|
（4）在组件中使用echarts
html中：
|
<div echarts [options]="chartOption" style="width: 100%; height: 560px;"></div>
|
ts中：
|
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
// 定义图表项
chartOption: any;
constructor(){}
ngOnInit(){
this.chartOption = {
title: {
text: '折线图堆叠'
},
tooltip: {
trigger: 'axis'
},
legend: {
data: ['邮件营销', '联盟广告', '视频广告', '直接访问', '搜索引擎']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
toolbox: {
feature: {
saveAsImage: {}
}
},
xAxis: {
type: 'category',
boundaryGap: false,
data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
},
yAxis: {
type: 'value'
},
series: [
{
name: '邮件营销',
type: 'line',
stack: '总量',
data: [120, 132, 101, 134, 90, 230, 210]
},
{
name: '联盟广告',
type: 'line',
stack: '总量',
data: [220, 182, 191, 234, 290, 330, 310]
},
{
name: '视频广告',
type: 'line',
stack: '总量',
data: [150, 232, 201, 154, 190, 330, 410]
},
{
name: '直接访问',
type: 'line',
stack: '总量',
data: [320, 332, 301, 334, 390, 330, 320]
},
{
name: '搜索引擎',
type: 'line',
stack: '总量',
data: [820, 932, 901, 934, 1290, 1330, 1320]
}
]
};
}
}
