亲爱的社区，
我正在尝试使用 pgfplots 版本 1.16 构建堆叠 y 条形图。堆叠条形图没有问题，但 x 轴的标签有问题。我正在尝试重建下图及其主标签和次标签。我在 pgfplots 手册中找不到类似的东西。也许有人知道这是如何工作的？
非常感谢您的帮助！

% restructured data file:
% - 'n' values are sorted ascending
% - added column 'z' to know which data belong to which measurement
% - added a dummy line at the end of each data set to produce an empty entry
% for the separation of the blocks
