關於做angular4引入echarts圖表

1.安裝ngx-echarts

npm install echarts --save

npm install ngx-echarts --save

---

2.在項目中引入echarts

在項目包配置文件中引入js腳本

//angular-cli.json文件

{
    "apps": [{
        "scripts":[
            "../node_modules/echarts/dist/echarts.min.js",
            "../node_modules/echarts/map/js/china.js",
            "../node_modules/echarts/dist/extension/bmap.js"
        ]
    }]
}

---

3.使用

echarts.module.ts

import { NgModule } from '@angular/core';
import { EchartsComponent } from './echarts/echarts.component';
import { AngularEchartsModule } from 'ngx-echarts';

@NgModule({
  imports: [
    AngularEchartsModule
  ],
  declarations: [EchartsComponent],
})
export class EchartsModule { }

echarts.component.ts

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-echarts',
  templateUrl: './echarts.component.html',
  styleUrls: ['./echarts.component.scss']
})
export class EchartsComponent implements OnInit {
  showloading:boolean = true;

  constructor() { 
    
    setTimeout(()=> {
      this.showloading = false;
    }, 3000);
  }

  ngOnInit() {
  }

echarts.component.html

    <div echarts [options] = "chartOption" [loading]="showloading" class="demo-chart"></div>
    <div echarts [options] = "Baroptions" [loading]="showloading" class="demo-chart"></div>
    <div echarts [options] = "linkoption" [loading]="showloading" class="demo-chart"></div>
    <div echarts [options] = "mapoption" [loading]="showloading" class="demo-chart"></div>

關於api文檔

[options]：與官方演示網站的選項相同
[dataset]：您可以忽略“options”中的“data”屬性，並用於dataset綁定系列數據。
[loading]：布爾屬性。當您的數據未准備好時，使用它來切換加載動畫的echarts。
theme：用它來初始化具有主題的echarts。你需要在主題文件.angular-cli.json或index.html。例如，如果我們要dark.js在Echarts主題頁面中使用：<div echarts theme = "dark" class = "demo-chart" [options] = "chartOptions"></div>這樣我們就使用成功dark主題了。
(chartInit)它暴露了echartsInstance 'chartInit'事件。所以，你可以直接調用的API一樣：resize()，showLoading()

---

例如

html

<div echarts class="demo-chart" [options]="chartOptions" (chartInit)="onChartInit($event)"></div>

ts

onChartInit(ec) {
  this.echartsIntance = ec;
}

resizeChart() {
  if (this.echartsIntance) {
    this.echartsIntance.resize();
    this.echartsIntance.showLoading();
  }
}

后續在更新吧！ 畢竟上班時間搞這個 (ૢ˃ꌂ˂ૢ)
