如何将 Donut Chart JS 放入 Bootstrap 列？

Question

我希望 Chart.js 中的甜甜圈图片适合我的 bootstrap 专栏。我还希望此列具有特定大小（实际上，我更关心高度）。问题是 canvas div 的大小实际上比我的专栏 div 大，所有图表都相互重叠。理想情况下，我希望所有 4 个图表都与行的右侧对齐，并且从右侧有一点 space（例如 10px 的边距）。

我试过在 div 和 canvas 列上使用 margin/padding 设置。想不通...

这里是jsfiddle例子

我的HTML:

<div class="row">
  <div class="col-sm-3">
    Some content
  </div>
  <div class="col-sm-3">
    Some other content
  </div>

  <div class="col-sm-2"></div>

  <div class="col-sm-1">
    <div class="chart-container" style="position: relative; width: 200px; height: 100px;">
      <canvas id="chart1" width="200" height="100"></canvas>
    </div>
  </div>
  <div class="col-sm-1">
    <div class="chart-container" style="position: relative; width: 200px; height: 100px;">
      <canvas id="chart2" width="200" height="100"></canvas>
    </div>
  </div>
  <div class="col-sm-1">
    <div class="chart-container" style="position: relative; width: 200px; height: 100px;">
      <canvas id="chart3" width="200" height="100"></canvas>
    </div>
  </div>
  <div class="col-sm-1">
    <div class="chart-container" style="position: relative; width: 200px; height: 100px;">
      <canvas id="chart4" width="200" height="100"></canvas>
    </div>
  </div>
</div>

还有我的 JS：

var myNewChart;
var data = [{
  value: 30,
  color: "#F7464A"
}, {
  value: 50,
  color: "#E2EAE9"
}, {
  value: 100,
  color: "#D4CCC5"
}, {
  value: 40,
  color: "#949FB1"
}, {
  value: 100,
  color: "#4D5360"
}];

var options = {
  animation: true,
  animationEasing: 'easeInOutQuart',
  animationSteps: 80
};

//Get the context of the canvas element we want to select
var ctx1 = document.getElementById("chart1")
  .getContext("2d");
var ctx2 = document.getElementById("chart2")
  .getContext("2d");
var ctx3 = document.getElementById("chart3")
  .getContext("2d");
var ctx4 = document.getElementById("chart4")
  .getContext("2d");

/*******************************************************/
myNewChart1 = new Chart(ctx1).Doughnut(data, options);
myNewChart2 = new Chart(ctx2).Doughnut(data, options);
myNewChart3 = new Chart(ctx3).Doughnut(data, options);
myNewChart4 = new Chart(ctx4).Doughnut(data, options);

Answer 1

您可以添加一些 CSS 以正确设置 Chart.js canvas 和 div 容器的样式：

canvas {
  width: 100%;
  height: 100%;
  display: block;
}

div.chart-container {
  padding: 1px;
}
