创建堆叠和分组的条形图：一个条形图被隐藏了吗？

Question

我有一组 4 条柱状图，我想为每个点绘制这些柱状图。我有 5 个点，所以我需要为每个点绘制 4 条柱状图。每条柱状图都堆叠了两个数据。

以下是代码，结果仅显示一组 3 堆叠条形图。有一个隐藏条形图。问题是什么？如何显示 4 堆叠条形图？

另外，我不知道为什么黄色的栏没有填满？！

结果如下：

Answer 1

在您的示例中，第二和第三个axis环境具有相同的bar shift（=0pt），因此它们重叠。

在下面的例子中，我依次为这四个环境指定bar shift到，并添加一个来加宽整个图形。-12pt, -4pt, 4pt, 12ptaxiswidth=10cm
