Y轴数值为0时怎么设置原点位置和X轴重合，Y轴落点值落在X轴上，如下图所示 ，版本5.1.20 #6306

目前展示成这样了

复现的demo

import { Chart } from '@antv/g2';
const chart = new Chart({
        container: 'case-report-trend',
        autoFit: true,
        marginBottom: 0,
        marginLeft: 0,
        marginRight: 10,
        title: '',
    });
    chart.data([
        { date: '06-10', count: 0, type: '测试' },
        { date: '06-11', count: 0, type: '测试' },
        { date: '06-12', count: 0, type: '测试' },
        { date: '06-13', count: 0, type: '测试' },
        { date: '06-14', count: 0, type: '测试' },
        { date: '06-15', count: 0, type: '测试' },
        { date: '06-16', count: 0, type: '测试' }
    ]);

    chart
        .line()
        .encode('x', 'date')
        .encode('y','count')
        .encode('shape', 'smooth')
        .encode('color', 'type')
        .scale('color', {
            domain: ['测试'],
            range: ['#FF9410'],
        })
        .style('lineWidth', 2)
        .legend(false)
        .scale('y', { independent: true, nice: true })
        .axis('x', {
            labelFill: '#fff',
            tickStroke: '#fff',
            lineStroke: '#fff',
            labelStroke: '#fff',
            labelFontSize: 12,
            tick: true,
            line: true,
            title: '',
        })
        .axis('y', {
            labelFill: '#fff',
            tickStroke: '#fff',
            lineStroke: '#fff',
            labelStroke: '#fff',
            gridStroke: '#fff',
            labelFontSize: 12,
            gridLineWidth: 1,
            gridLineDash: [1, 0],
            tick: true,
            grid: true,
            title: '',
            labelFormatter: (v: any) =>
                v >= 10000 ? (v / 10000).toFixed(0) + '万' : v,
        })
        .tooltip({ items: [{ channel: 'y', name: '测试' }] });
    chart.render();

可以这样哈：

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

const chart = new Chart({
  container: 'container',
});

chart.data([
  { date: '06-10', count: 0, type: '测试' },
  { date: '06-11', count: 0, type: '测试' },
  { date: '06-12', count: 0, type: '测试' },
  { date: '06-13', count: 0, type: '测试' },
  { date: '06-14', count: 0, type: '测试' },
  { date: '06-15', count: 0, type: '测试' },
  { date: '06-16', count: 0, type: '测试' },
]);

chart
  .line()
  .encode('x', 'date')
  .encode('y', 'count')
  .scale('y', {
    domain: [0, 1],
  });

chart.render();

你可以把代码复制到官网 demo 里面看看，主要是加入下面一行：

  .scale('y', {
    domain: [0, 1],
  });

嗯 可以了， 参数数组后面这个1需要根据数据动态计算得出
