Question

是否可以插入自定义 HTML 代码作为条形图的 xaxisLabel？

喜欢

xaxisLabels: ['<i class="fa fas fa-check fa-2x"></i>']

在结果中，缺少结束标记 (</i>)。

没有向标签添加自定义 HTML 的选项，但由于标签是 DOM 节点（如果您使用的是 DOM 文本 - 默认情况下处于打开状态），您可以以这种方式操纵它们让你心满意足。这是一个例子：

<!DOCTYPE html>
<html>
<head>
    <script src="https://www.rgraph.net/libraries/RGraph.common.core.js"></script>
    <script src="https://www.rgraph.net/libraries/RGraph.bar.js"></script>
</head>
<body>

    <h1>Clickable labels</h1>

    <canvas id="cvs1" width="600" height="250">[No canvas support]</canvas>

    <script>
        bar = new RGraph.Bar({
          id:'cvs1',
          data: '8,4,6,3,5,4,2'.split(','),
          options: {
            xaxisLabels: ['Mon','Tue','Wed','Thu','Fri','Sat','Sun'],
            textAccessiblePointerevents: true,
            
            // If you just want to manipulate the style of the labels
            // there are these five properties

            //xaxisLabelsSize: 16,
            //xaxisLabelsFont: 'Verdana',
            //xaxiLabelsBold: true,
            //xaxisLabelsItalic: true,
            //xaxisLabelsColor: 'red'
          }
        }).draw();
        
        labels = document.getElementsByClassName('rgraph_accessible_text_xaxis_labels');

        // Maniuplate the style
        for (i=0; i<labels.length; ++i) {
            labels[i].style.fontWeight = 'bold';
            labels[i].style.fontStyle  = 'italic';
            labels[i].style.fontSize   = '14pt';
            labels[i].style.color      = 'red';
            labels[i].style.fontFamily = 'Verdana';
        }
        
        // Add a click event listener
        labels[0].addEventListener('click', function (e)
        {
            alert('Label was clicked');
        }, false);
        
        // Add a mousemove event listener
        labels[0].addEventListener('mousemove', function (e)
        {
            e.target.style.cursor = 'pointer';
        }, false);
    </script>
    

</body>
</html>

编辑：

此外，您还可以在创建图表后使用 RGraph.text.find() 函数，如下所示：

labels = RGraph.text.find({
  object: bar,
    text: 'Wed'
});

labels[0].style.fontWeight = 'bold';
labels[0].style.cursor     = 'pointer';
labels[0].addEventListener('click', function (e)
{
    alert('My label!');
}, false);
