利用 `mask` 和 `maskSlider` 来改变时间格式。

```ts
import { Component, OnInit } from '@angular/core';
import { G2TimelineClickItem, G2TimelineData } from '@ohayo/chart/timeline';
import { NzMessageService } from 'ng-zorro-antd/message';

@Component({
  selector: 'app-demo',
  template: ` <g2-timeline
    [data]="chartData"
    [titleMap]="{ y1: '客流量', y2: '支付笔数' }"
    [height]="200"
    mask="MM月DD日"
    maskSlider="MM月dd日"
    (clickItem)="handleClick($event)"
  ></g2-timeline>`,
})
export class DemoComponent implements OnInit {
  chartData: G2TimelineData[] = [];

  constructor(private msg: NzMessageService) {}

  ngOnInit(): void {
    for (let i = 0; i < 20; i += 1) {
      this.chartData.push({
        time: new Date().getTime() + 1000 * 60 * 60 * 24 * i,
        y1: Math.floor(Math.random() * 100) + 1000,
        y2: Math.floor(Math.random() * 100) + 10,
      });
    }
  }

  handleClick(data: G2TimelineClickItem): void {
    this.msg.info(`客流量: ${data.item.y1}, 支付笔数: ${data.item.y2}`);
  }
}
```
