在堆积条形图中标记区域

在堆积条形图中标记区域

我正在尝试创建一个堆积条形图，同时标记其各个部分（连接的部分）。

在这种情况下，这种axis cs方法似乎有效，但我面临两个问题：

  1. 轮廓几乎不可见。我尝试过pgfonlayer，但没有成功。我希望它完全可见。

  2. 轮廓太小。它与xticks 匹配，但与ybar区域本身不匹配，看起来有点奇怪。

我该如何解决这些问题？

这是我当前的代码：

答案1

第一点可以通过层来解决，例如 这里例如。我的建议直接来自那里。第二点是由于bar width没有考虑到。如果增加图的大小，你就会看到这一点。我想用移动矩形点\pgfplotbarwidth，但由于日期的原因，计算似乎失败了，我不明白为什么。

希望这可以为其他人提供信息来解决这个问题。

编辑

bar plot这是更新版本，我认为s 和之间缺少接口datetime。具体来说，应该能够使用bar width在这种情况下失败的单元。所以我对值进行了一些调整，以获得一些东西正确的。使用(+/-\pgfplotbarwidth/2,0pt)shift 来计算条形宽度。注意使用0pt而不是 ，0否则编译会失败。
