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, people: 5 },
  { 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',
  autoFit: true,
});

chart.data(data);

chart
  .interval()
  .encode('x', 'time')
  .encode('y', 'waiting')
  .axis('y', { title: 'Waiting', titleFill: '#5B8FF9' });

chart
  .line()
  .encode('x', 'time')
  .encode('y', 'people')
  .encode('shape', 'smooth')
  .style('stroke', '#fdae6b')
  .style('lineWidth', 2)
  .scale('y', { independent: true })
  .axis('y', {
    position: 'right',
    grid: null,
    title: 'People',
    titleFill: '#fdae6b',
  });

chart.render();

通过 scale.y.domain 设置：

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, people: 5 },
  { 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',
  autoFit: true,
});

chart.data(data);

chart
  .interval()
  .encode('x', 'time')
  .encode('y', 'waiting')
  .axis('y', { title: 'Waiting', titleFill: '#5B8FF9' });

chart
  .line()
  .encode('x', 'time')
  .encode('y', 'people')
  .encode('shape', 'smooth')
  .style('stroke', '#fdae6b')
  .style('lineWidth', 2)
  .scale('y', { independent: true, domain:[-10, 10] }) // 这里
  .axis('y', {
    position: 'right',
    grid: null,
    title: 'People',
    titleFill: '#fdae6b',
  });

chart.render();
