I'm trying to remove the stroke color from the legend generated by ChartJS, but I can't quite seem to understand what the documentation is telling me.

My current code looks like this:

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

Though I have tried this:

generateLabels: {
  strokeStyle: "black",
}

I'm setting the stroke style to "black" to see if I'm having any effect, but I'm not even sure if that's what I'm supposed to be doing. I would think I could set it to none.

Edit

Here is the code for my full object:

    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,
      }
    });

But now that I run it here, it seems to be working. So I'm not sure what's wrong anymore.

• javascript
• chart.js

• And I can't figure out what that error is in the code snippet either, if anybody wants to fix it. – Logan Waite Commented Jul 10, 2017 at 21:35

To remove the stroke from legend, you need to set borderWidth property to 0 for your dataset, like so ...

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
            }
         }]
      }
   }
});
