需要帮助设计图表JS雷达图

Question

我正试图在下面的链接雷达图中添加背景样式，并希望能够

• 设置雷达线路的颜色
• 定厚
• 将标度从0-100设置为
• 设置字体大小

我认为这必须通过“选项”来完成(因为这不是关于数据集的)，但是我对JS的掌握还不足以让它在几个小时后开始工作。

new Chart(document.getElementById("radar-chart"), {
type: 'radar',
data: {
  labels: ["Business", "Brand", "Marketing", "Stakeholders", "Clients"],
  datasets: [
     {
      label: "",
      fill: true,
      backgroundColor: "rgba(255,99,132,0.2)",
      borderColor: "rgba(255,99,132,1)", 
      pointBorderColor: "#fff",
      pointBackgroundColor: "rgba(255,99,132,1)",
      pointBorderColor: "#fff",
      data: [25.48,54.16,7.61,8.06,4.45]
    }
  ]
},  

options: {

legend: {
  display: false    
},
borderWidth: 10,

}

});

Answer 1

为了获得所要求的内容，可以在ticks、gridLines和pointLabels中定义options.scale。

​

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"
      }
    }  
  }
});
