具有边界的时间序列填充模式（tikz pgfplots）

Question

我想绘制三个时间序列；其中两个有界限。事实上，它看起来类似于此处显示的图： 绘制两个有边界的时间序列

在我的例子中，两个有边界的时间序列的两个区域重叠相当多，因此生成的图像不太容易理解。目前，我正在使用以下代码：

\pgfplotstableread{

相应的图表如下：

为了更好地区分这两个区域，我想用西北线填充一个区域，用西南线填充另一个区域。但是，使用“图案”命令并不适用于“堆叠”命令。因此，我的第一个问题是如何用图案填充这些区域。

有用户将解决方案显示为 png 文件（下面是 Harish 的评论），但用户没有发布代码。有人知道该解决方案的 latex 代码吗？

Answer 1

好了，任务很简单，加载patternstikz 库，然后fill使用pattern：

\addplot [stack plots=y, pattern=north west lines,pattern color=red!50, opacity=0.4, draw opacity=0, area legend]   table [x=temps, y expr=\thisrow{y_h__sup}-\thisrow{y_h__inf}]   {\table} \closedcycle;
