原始答案

只需配置图表隐藏线的选项

segmentShowStroke: false

像这样:

//创建图表var ctx = document.getElementById("myChart").getContext("2d");变量数据 = [{价值:300，颜色:#F7464A"，亮点:#FF5A5E"，标签:红色"}, {价值:50，颜色:#46BFBD"，亮点:#5AD3D1"，标签:绿色"}, {值:100，颜色:#FDB45C"，亮点:#FFC870"，标签:黄色"}];变量选项 = {//Boolean - 我们是否应该在每个段上显示一个笔划//设置为 false 以隐藏段之间的空间/线段ShowStroke:假};//对于饼图var myPieChart = new Chart(ctx).Pie(data, options);

<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.js"></script><canvas id="myChart" width="200" height="200"></canvas>

I am using Chart.js pie chart and I'd like to remove white lines between slices. Could someone tell me way to do this ? Thanks in advance

I didn't see anything in the documenation.

    <div class="pie-chart">
         <div id="canvas-holder">
              <canvas id="chart-area" width="250" height="250"/>
         </div>
    </div>

Original answer

Just configure the options for the chart to hide the line

segmentShowStroke: false

Something like this:

//create chart
var ctx = document.getElementById("myChart").getContext("2d");

var data = [{
  value: 300,
  color: "#F7464A",
  highlight: "#FF5A5E",
  label: "Red"
}, {
  value: 50,
  color: "#46BFBD",
  highlight: "#5AD3D1",
  label: "Green"
}, {
  value: 100,
  color: "#FDB45C",
  highlight: "#FFC870",
  label: "Yellow"
}];

var options = {
  //Boolean - Whether we should show a stroke on each segment
  // set to false to hide the space/line between segments
  segmentShowStroke: false
};

// For a pie chart
var myPieChart = new Chart(ctx).Pie(data, options);

<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.js"></script>
<canvas id="myChart" width="200" height="200"></canvas>
