使用AG Grid的API手动重绘图表

在使用AG Grid中的图表功能时，如果出现图表显示不出来的情况，可以尝试手动调用AG Grid的API进行重绘。具体实现方式如下：

1. 导入AG Grid模块：

import {AgChartsAngularModule} from 'ag-charts-angular';

2. 在图表组件的HTML模板中添加AG Grid的图表标签，如：

3. 在图表组件的TS文件中定义AG Grid的图表配置项，如：

public chartOptions: any = {
    series: [{
        type: 'column',
        xKey: 'name',
        yKeys: ['value'],
        groupBy: 'year',
        fills: ['#89CFF0', '#FFC125', '#FF7F50'],
        strokes: ['#1E90FF', '#CD853F', '#FF4500']
    }]
};

4. 在图表组件的TS文件中定义AG Grid的图表数据，如：

public chartData: any = [
    {year: '2015', value: 15, name: 'Series 1'},
    {year: '2015', value: 25, name: 'Series 2'},
    {year: '2015', value: 35, name: 'Series 3'},
    {year: '2016', value: 10, name: 'Series 1'},
    {year: '2016', value: 20, name: 'Series 2'},
    {year: '2016', value: 30, name: 'Series 3'},
    {year: '2017', value: 5, name: 'Series 1'},
    {year: '2017', value: 15, name: 'Series 2'},
    {year: '2017', value: 25, name: 'Series 3'}
];

5. 在图表组件的TS文件中通过AG Grid的API手动重绘图表，如：

import {Component, OnInit, ViewChild} from '@angular/core';
import {AgChartsAngular} from 'ag-charts-angular';
 
@Component({
    selector: 'app-column-chart',
    templateUrl: './column-chart.component.html',
    styleUrls: ['./column-chart.component.scss']
})
export class ColumnChartComponent implements OnInit {
 
    @ViewChild('agCharts', { static: true }) agCharts: AgChartsAngular;
 
    public chartOptions: any = {
        series: [{
            type: 'column',
            xKey: 'name',
            yKeys: ['value'],
            groupBy: 'year',
            fills: ['#89CFF0', '#FFC125', '#FF7F50'],
            strokes: ['#1E90FF', '#CD853F', '#FF4500']
        }]
    };
 
    public chartData: any = [
        {year: '2015', value: 15, name: 'Series 1'},
        {year: '2015', value: 25, name: 'Series 2'},
        {year: '2015', value: 35, name: 'Series 3'},
        {year: '2016', value: 10, name: 'Series 1
