【v5】折线图断掉的地方往后，label 不显示了

[Deathsteps]

问题描述

期望结果

线可以断了再续，label 应该也一样

如何重现

官方代码修改

import { Chart } from '@antv/g2';

const data = [
  { time: '10:10', call: 4, waiting: 2, people: 2 },
  { time: '10:15', call: 2, waiting: 6, people: 3 },
  { time: '10:20', call: 13, waiting: 2 },
  { time: '10:25', call: 9, waiting: 9, people: 1 },
  { time: '10:30', call: 5, waiting: 2, people: 3 },
  { time: '10:35', call: 8, waiting: 2, people: 1 },
  { time: '10:40', call: 13, waiting: 1, people: 2 },
];

const chart = new Chart({
  container: 'container',
  theme: 'classic',
  autoFit: true,
});

chart.data(data);

chart
  .line()
  .encode('x', 'time')
  .encode('y', 'people')
  .encode('shape', 'smooth')
  .label({ text: 'people' });

chart.render();
