antv g2 plot 怎么不展现另外一个数字的y轴

如果您想在 G2 Plot 中展示另一个数字的 y 轴，可以使用 `dual-axes`（双轴）模式。以下是一个简单的示例代码：

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

const data = [
  { year: '1991', value: 15468, count: 110 },
  { year: '1992', value: 16100, count: 90 },
  { year: '1993', value: 15900, count: 120 },
  { year: '1994', value: 17409, count: 150 },
  { year: '1995', value: 17000, count: 170 },
  { year: '1996', value: 31056, count: 200 },
  { year: '1997', value: 31982, count: 250 },
  { year: '1998', value: 32040, count: 300 },
  { year: '1999', value: 33233, count: 350 },
  { year: '2000', value: 34241, count: 400 },
  { year: '2001', value: 34368, count: 450 },
  { year: '2002', value: 32961, count: 500 },
  { year: '2003', value: 34434, count: 550 },
  { year: '2004', value: 35521, count: 600 },
  { year: '2005', value: 35415, count: 650 },
  { year: '2006', value: 37790, count: 700 },
  { year: '2007', value: 41000, count: 750 },
  { year: '2008', value: 40603, count: 800 },
  { year: '2009', value: 50000, count: 850 },
  { year: '2010', value: 55000, count: 900 },
  { year: '2011', value: 55200, count: 950 },
  { year: '2012', value: 58400, count: 1000 },
  { year: '2013', value: 60000, count: 1050 },
  { year: '2014', value: 60200, count: 1100 },
  { year: '2015', value: 62000, count: 1150 },
  { year: '2016', value: 65000, count: 1200 },
  { year: '2017', value: 66000, count: 1250 },
  { year: '2018', value: 67600, count: 1300 },
  { year: '2019', value: 68700, count: 1350 },
];

const chart = new Chart({
  container: 'container',
  autoFit: true,
  height: 500,
});

chart.data(data);

// 配置 value 轴
chart.scale('value', {
  nice: true,
});

// 配置 count 轴
chart.scale('count', {
  nice: true,
});

// 绘制 value 系列数据
chart
  .line()
  .position('year*value')
  .color('red');

// 绘制 count 系列数据
chart
  .line()
  .position('year*count')
  .color('blue')
  .axis('count', {
    label: {
      formatter: (val) => `${val} 个`,
    },
  });

// 开启双轴模式
chart.axis('count', {
  grid: null,
  line: null,
  tickLine: null,
});
chart.axis('value', {
  label: {
    formatter: (val) => `$${val}`,
  },
});

chart.render();

在这个示例中，我们使用了 `dual-axes` 模式来同时展示 `value` 和 `count` 两个数字的 y 轴。其中 `value` 轴使用了默认的设置，而 `count` 轴则进行了定制化，例如添加了单位（个），并且取消了其网格、线条和刻度线。

希望能对您有所帮助！
