Chart.JS - 无法在 Y 轴标签之间添加边距/间距

Question

1. 在 Y 轴标签上应用边距的任何方式。就像我在 Y 轴上的流派名称一样，需要在它们之间添加更多的空间/边距才能看得清楚。
2. 我几乎尝试了他们提供的所有选项，但都没有得到想要的结果。
3. 参考：https://www.chartjs.org/docs/latest/axes/
4. 我找不到任何东西边距是 Y 轴上的字符串值。

Answer 1

两件事，您使用的是 chart.js 的 v2，并且您链接的文档适用于 V3，对于 v2 文档，您必须像这样指定特定版本：https://www.chartjs.org/docs/2.9.4/

对于刻度，如果您将 autoSkip 设置为 true 而不是 false，chart.js 应该自动跳过标签以便它们不会重叠，然后您还可以告诉 chart.js 您希望它们之间有多少空间 @987654323 @property 请参见下面的示例。如果您真的想显示所有标签，除了让图表在物理上更大之外别无选择，因为 chart.js 需要更多垂直空间，请正确显示所有标签

带有额外填充的跳过示例：

var options = {
  type: 'line',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3, 12, 19, 3, 5, 2, 3],
      borderWidth: 1
    }]
  },
  options: {
    scales: {
      xAxes: [{
        ticks: {
          autoSkipPadding: 100
        }
      }]
    }
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
