在Plotly javascript中控制轴值的权重/粗体

var data = [
  {
    x: [1, 2, 3, 4, 5],
    y: [1, 4, 9, 16, 25],
    type: 'scatter'
  }
];

var layout = {
  xaxis: {
    tickfont: {
      weight: 'bold' // 设置轴刻度标签的字体粗细
    }
  },
  yaxis: {
    tickfont: {
      weight: 'bold' // 设置轴刻度标签的字体粗细
    }
  }
};

Plotly.newPlot('myDiv', data, layout);
