d3js/nvd3-图形半隐藏

我有一个d3/nvd3图，它似乎被"剪裁"了一半。。。下面是代码（抱歉，很长，但在html文件中复制/粘贴是可行的）。通常我每小时有一个酒吧（所以24个酒吧），我只放了三个小时。html分为几个部分：

1. 图例[g class="nv-x nv-axis" transform="translate(0,235)"]
2. Y轴：[g class="nv-y nv-axis"]
3. 一个酒吧按小时：[g class="nv-barsWrap"]

我们只看到Y轴和条形图的上半部分，底部的图例丢失了。但它确实存在于html上！我们可以"检查"它…我不知道发生了什么，但有一个"剪辑"矩形我不掌握。。。（[clipPath id="nv-x-label-clip-6678"]）
