我使用Chart.js(http://www.chartjs.org/),它的工作正常,但我有太大的X标签也与45度方向(是自动调整)。我想减少该文本的大小,是否可以只为X轴做?谢谢

是的,在tickes.fontSize配置中,您只能对x轴执行此操作

var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
  type: 'bar',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3],
      backgroundColor: [
        'rgba(255, 99, 132, 0.2)',
        'rgba(54, 162, 235, 0.2)',
        'rgba(255, 206, 86, 0.2)',
        'rgba(75, 192, 192, 0.2)',
        'rgba(153, 102, 255, 0.2)',
        'rgba(255, 159, 64, 0.2)'
      ],
      borderColor: [
        'rgba(255,99,132,1)',
        'rgba(54, 162, 235, 1)',
        'rgba(255, 206, 86, 1)',
        'rgba(75, 192, 192, 1)',
        'rgba(153, 102, 255, 1)',
        'rgba(255, 159, 64, 1)'
      ],
      borderWidth: 1
    }]
  },
  options: {
    scales: {
      yAxes: [{
        ticks: {
          beginAtZero: true
        }
      }],
      xAxes: [{
        ticks: {
          fontSize: 8
        }
      }]
    }
  }
});

对于3.5.1版本,它是:
options.scales.x.ticks.font.size = $FONT_SIZE
