更改图例框大纲Chart.js 2

Question

我正在尝试从ChartJS生成的图例中删除笔触颜色,但我似乎无法理解文档告诉我的内容.

我当前的代码如下所示:

legend: {
  position: 'bottom',
    labels: {
      generateLabels: function() {
        return {
          strokeStyle: "black",
        }
      }
    }
  }

虽然我试过这个:

generateLabels: {
  strokeStyle: "black",
}

我将笔画样式设置为"黑色",看看我是否有任何效果,但我甚至不确定这是否是我应该做的.我想我可以把它设置为无.

这是我的完整对象的代码:

    var ctx = $('#chart');
    var data = {
        labels: ["1","2","3","4","5","6","7"],
        datasets: [{
            data: [22,19,17,15,10,9,8],
            backgroundColor: [
                '#df4344',
                '#fc9627',
                '#fcd949',
                '#d4d81e',
                '#6dc7ba',
                '#24a38e',
                '#263a7e',
                '#5050b2',
                '#4f7ec1',
                '#96afe2',
            ],
            borderColor: ["black"],
            borderWidth: 2
        }]
     };

    var wheel = new Chart(ctx, {
      type: "doughnut",
      data: data,
      options: {
        maintainAspectRatio: false,
        responsive: true,
        tooltips: false,
        cutoutPercentage: 60,
      }
    });

但是现在我在这里运行它似乎正在工作.所以我不知道什么是错的.

要从图例中删除笔划,您需要为数据集设置borderWidth属性0,如下所示...

datasets: [{
   borderWidth: 0,
   ...
}]

var ctx = c.getContext('2d');
var chart = new Chart(ctx, {
   type: 'line',
   data: {
      labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May'],
      datasets: [{
         label: 'Statistics',
         data: [3, 1, 2, 5, 4],
         backgroundColor: 'rgba(0, 119, 204, 0.1)',
         borderColor: 'rgba(0, 119, 204, 0.8)',
         borderWidth: 0 //<-- set this
      }]
   },
   options: {
      scales: {
         yAxes: [{
            ticks: {
               beginAtZero: true
            }
         }]
      }
   }
});
