基本

最简单的用法。

expand codeexpand code
import { Component } from '@angular/core';
import { ChartEChartsEvent, ChartEChartsOption } from '@delon/chart/chart-echarts';

@Component({
  selector: 'chart-chart-echarts-basic',
  template: `
    <div class="mb-md">
      <nz-switch [(ngModel)]="dark"></nz-switch> Dark
      <button nz-button (click)="two = !two" nzType="primary">Change Option</button>
    </div>
    <chart-echarts [option]="two ? option1 : option2" [theme]="dark ? 'dark' : null" (events)="handleEvents($event)"></chart-echarts>
  `,
})
export class ChartChartEchartsBasicComponent {
  dark = false;
  two = false;

  option1: ChartEChartsOption = {
    tooltip: {
      formatter: '{a} <br/>{b} : {c}%',
    },
    series: [
      {
        name: 'Pressure',
        type: 'gauge',
        detail: {
          formatter: '{value}',
        },
        data: [
          {
            value: 50,
            name: 'SCORE',
          },
        ],
      },
    ],
  };

  option2: ChartEChartsOption = {
    title: {
      text: 'ECharts 入门示例',
    },
    tooltip: {},
    legend: {
      data: ['销量'],
    },
    xAxis: {
      data: ['衬衫', '羊毛衫', '雪纺衫', '裤子', '高跟鞋', '袜子'],
    },
    yAxis: {},
    series: [
      {
        name: '销量',
        type: 'bar',
        data: [5, 20, 36, 10, 10, 20],
      },
    ],
  };

  handleEvents(ev: ChartEChartsEvent): void {
    console.log(ev);
  }
}

绑定事件

使用 on 属性,等同于 ECharts on

expand codeexpand code
import { Component } from '@angular/core';

import { ChartEChartsOn, ChartEChartsOption } from '@delon/chart/chart-echarts';
import { NzMessageService } from 'ng-zorro-antd/message';

@Component({
  selector: 'chart-chart-echarts-on',
  template: ` <chart-echarts [option]="option" [on]="on"></chart-echarts> `
})
export class ChartChartEchartsOnComponent {
  dark = false;
  two = false;

  on: ChartEChartsOn[] = [
    {
      eventName: 'click',
      handler: ({ event, chart }) => {
        this.msg.info(`${event.type}: ${event.name} - ${event.value} (${chart.id})`);
      }
    }
  ];

  option: ChartEChartsOption = {
    xAxis: {
      type: 'category',
      data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
    },
    yAxis: {
      type: 'value'
    },
    series: [
      {
        data: [150, 230, 224, 218, 135, 147, 260],
        type: 'line'
      }
    ]
  };

  constructor(private msg: NzMessageService) {}
}
