需要帮助样式图表 JS 雷达图表

Question

我正在尝试为下面链接的雷达图设置背景样式，并希望能够

• 设置雷达线的颜色
• 设置厚度
• 将比例设置为 0-100
• 设置字体大小

我认为这必须通过“选项”来完成（因为这与数据集无关）但我没有足够的 JS 掌握在几个小时的尝试后让它工作。

为了得到你想要的，你可以在options.scale中定义ticks、gridLines和pointLabels。

new Chart(document.getElementById("radar-chart"), {
  type: 'radar',
  data: {
    labels: ["Business", "Brand", "Marketing", "Stakeholders", "Clients"],
    datasets: [{
      data: [25.48, 54.16, 7.61, 8.06, 4.45],
      fill: true,
      backgroundColor: "rgba(255,99,132,0.2)",
      borderColor: "rgba(255,99,132,1)",
      pointBorderColor: "#fff",
      pointBackgroundColor: "rgba(255,99,132,1)"
    }]
  },
  options: {
    legend: {
      display: false
    },
    borderWidth: 10,
    scale: {
      ticks: {
        fontSize: 18,
        max: 100
      },
      gridLines: {
        lineWidth: 2,
        color: "lightgreen"
      },
      pointLabels: {
        fontSize: 18,
        fontStyle: "bold"
      }
    }  
  }
});
