在Chart.js中更改对数刻度的底

var config = {
  type: 'line',
  data: {
    labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
    datasets: [{
      label: 'My Dataset',
      data: [10, 100, 1000, 10000, 100000, 1000000, 10000000],
      backgroundColor: 'rgba(0, 123, 255, 0.5)'
    }]
  },
  options: {
    scales: {
      yAxes: [{
        type: 'logarithmic',
        ticks: {
          min: 1,
          max: 10000000,
          callback: function(value, index, values) {
            return Number(value.toString()); // 将刻度标签转换为数字格式
          }
        }
      }]
    }
  }
};

// 创建图表
var ctx = document.getElementById('myChart').getContext('2d');
new Chart(ctx, config);
