Angular2+ 集成ngx-echarts

注：

• github：https://github.com/xieziyu/ngx-echarts

• 官方网站：https://xieziyu.github.io/ngx-echarts/#/home

• echarts图表实例参考：http://echarts.baidu.com/examples/

1.通过使用npm进行引入相关依赖

npm install echarts -S
npm install ngx-echarts -S
npm install @types/echarts -D

在angular.json中引入echarts.min.js

 "scripts": [
     ....
     "node_modules/echarts/dist/echarts.min.js"
 ]

如果需要ECharts GL,则需要引入以下依赖

npm install echarts-gl -S

2.在module中导入ngx-echarts的模块

import {NgModule} from '@angular/core';
import {CommonModule} from '@angular/common';
import {RouterModule} from '@angular/router';
import {NgxEchartsModule} from 'ngx-echarts';
import {EEchartComponent} from './e-echart.component';

@NgModule({
    declarations: [EEchartComponent],
    imports: [
        CommonModule,
        NgxEchartsModule,
        RouterModule.forChild([{
            path: '', component: EEchartComponent,
            children: [
                {path: '', redirectTo: '', pathMatch: 'full'}
            ]
        }])
    ]
})
export class EEchartModule {
}

3.在html中编写echart图表代码

<div echarts [options]="chartOption" style="height: 400px" class="demo-chart"></div>
<div echarts [options]="option" style="height: 400px" class="demo-chart"></div>

4.在component中配置echart的options(配置信息)

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

@Component({
    selector: 'app-e-echart',
    templateUrl: './e-echart.component.html',
    styleUrls: ['./e-echart.component.scss']
})
export class EEchartComponent implements OnInit {
    // 这些配置文件可以直接从echart中的官网去拉取，该组件完全支持echart的所有图形
    public chartOption: EChartOption;
    public option: EChartOption;

    constructor() {
        this.chartOption = {
            xAxis: {
                type: 'category',
                data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
            },
            yAxis: {
                type: 'value'
            },
            series: [{
                data: [820, 932, 901, 934, 1290, 1330, 1320],
                type: 'line'
            }]
        };
        this.option = {
            tooltip: {
                trigger: 'axis',
                axisPointer: {            // 坐标轴指示器，坐标轴触发有效
                    type: 'shadow'        // 默认为直线，可选为：'line' | 'shadow'
                }
            },
            legend: {
                data: ['直接访问', '邮件营销', '联盟广告', '视频广告', '搜索引擎']
            },
            grid: {
                left: '3%',
                right: '4%',
                bottom: '3%',
                containLabel: true
            },
            xAxis: {
                type: 'value'
            },
            yAxis: {
                type: 'category',
                data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
            },
            series: [
                {
                    name: '直接访问',
                    type: 'bar',
                    stack: '总量',
                    label: {
                        normal: {
                            show: true,
                            position: 'insideRight'
                        }
                    },
                    data: [320, 302, 301, 334, 390, 330, 320]
                },
                {
                    name: '邮件营销',
                    type: 'bar',
                    stack: '总量',
                    label: {
                        normal: {
                            show: true,
                            position: 'insideRight'
                        }
                    },
                    data: [120, 132, 101, 134, 90, 230, 210]
                },
                {
                    name: '联盟广告',
                    type: 'bar',
                    stack: '总量',
                    label: {
                        normal: {
                            show: true,
                            position: 'insideRight'
                        }
                    },
                    data: [220, 182, 191, 234, 290, 330, 310]
                },
                {
                    name: '视频广告',
                    type: 'bar',
                    stack: '总量',
                    label: {
                        normal: {
                            show: true,
                            position: 'insideRight'
                        }
                    },
                    data: [150, 212, 201, 154, 190, 330, 410]
                },
                {
                    name: '搜索引擎',
                    type: 'bar',
                    stack: '总量',
                    label: {
                        normal: {
                            show: true,
                            position: 'insideRight'
                        }
                    },
                    data: [820, 832, 901, 934, 1290, 1330, 1320]
                }
            ]
        };

    }

    ngOnInit() {
    }

}

注：代码中的options都是参考echarts图表实例参考,组件ngx-echarts是完全支持echarts的图表的，下图中有的都可以在ngx-echarts中使用
