javascript - Bootstrap 卡片中的响应式 PlotlyJS 图表

Question

以下是我使用 PlotlyJS 绘制响应图的 js 代码。

var trace1 = {
  x: ['Category A', 'Category B', 'Category C', 'Category D ', 'Category E', 'Category F', 'Category G', 'Category H'],
  y: [20, 14, 23, 20, 14, 23, 34, 26],
  marker: {
    color: ['rgba(0,152,212,0.5)', 'rgba(0,152,212,0.5)', 'rgba(0,152,212,0.5)', 'rgba(0,152,212,0.5)', 'rgba(0,152,212,0.5)', 'rgba(0,152,212,0.5)', 'rgba(0,152,212,0.5)', 'rgba(0,152,212,0.5)']
  },
  name: 'Item 1',
  type: 'bar'
};

var trace2 = {
  x: ['Category A', 'Category B', 'Category C', 'Category D ', 'Category E', 'Category F', 'Category G', 'Category H'],
  y: [12, 18, 29, 12, 18, 29, 24, 22],
  marker: {
    color: ['rgba(0,152,212,1)', 'rgba(0,152,212,1)', 'rgba(0,152,212,1)', 'rgba(0,152,212,1)', 'rgba(0,152,212,1)', 'rgba(0,152,212,1)', 'rgba(0,152,212,1)', 'rgba(0,152,212,1)']
  },
  name: 'Item 2',
  type: 'bar'
};

var trace3 = {
  x: ['Category A', 'Category B', 'Category C', 'Category D ', 'Category E', 'Category F', 'Category G', 'Category H'],
  y: [12, 18, 29, 12, 18, 29, 24, 22],
  marker: {
    color: ['rgba(0,54,136,1)', 'rgba(0,54,136,1)', 'rgba(0,54,136,1)', 'rgba(0,54,136,1)', 'rgba(0,54,136,1)', 'rgba(0,54,136,1)', 'rgba(0,54,136,1)', 'rgba(0,54,136,1)']
  },
  name: 'Item 3',
  type: 'bar'
};

var data = [trace1, trace2, trace3];

var layout = {
  barmode: 'stack',
};

Plotly.newPlot('myDivPlotly', data, layout);

// code to make plotlyjs responsive
(function() {
  var d3 = Plotly.d3;
  var WIDTH_IN_PERCENT_OF_PARENT = 100,
      HEIGHT_IN_PERCENT_OF_PARENT = 100;

  var gd3 = d3.selectAll(".responsive-plot")
      .style({
        width: WIDTH_IN_PERCENT_OF_PARENT + '%',
        'margin-left': (100 - WIDTH_IN_PERCENT_OF_PARENT) / 2 + '%',

        height: HEIGHT_IN_PERCENT_OF_PARENT + 'vh',
        'margin-top': (100 - HEIGHT_IN_PERCENT_OF_PARENT) / 2 + 'vh'
      });

  var nodes_to_resize = gd3[0]; //not sure why but the goods are within a nested array
  window.onresize = function() {
    for (var i = 0; i < nodes_to_resize.length; i++) {
      Plotly.Plots.resize(nodes_to_resize[i]);
    }
  };

})();

以下是我的 HTML 代码，用于在 Bootstrap 卡片中绘制 plotlyJS 图表。

<div class="container">
  <div class="row">
    <div class="col-md-6">
      <div class="card">
        <h5 class="card-header">Featured</h5>
        <div class="card-body">
          <h5 class="card-title">Special title treatment</h5>
          <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
          <a href="#" class="btn btn-primary">Go somewhere</a>
        </div>
      </div>
    </div>
    <div class="col-md-6">
      <div class="card">
        <h5 class="card-header">Featured</h5>
        <div class="card-body">
          <div class="responsive-plot" id="myDivPlotly">
        </div>
      </div>
    </div>
  </div>
</div>

图表现在可以响应，但问题是该图上方和下方有很多空白空间。如何移除绘图周围的空白空间或降低卡片的高度。

请帮忙。谢谢。

您必须做一些小事来删除底部的空白区域。但是在顶部边缘有一个隐藏的绘图栏，只有当鼠标悬停在它上面时才会显示。您必须在 .js 文件中更改这些内容。

var gd3 = d3.selectAll(".responsive-plot")
        .style({
          width: 'fit-content',
          'margin-left': (100 - WIDTH_IN_PERCENT_OF_PARENT) / 2 + '%',

          height: 'fit-content',
          'margin-top': '0vh'
        });
