我有几张图表想要通过条形图来表示。最初，我考虑将图表分组在一起（如图 A 所示），但由于我将有几张不同的图表，为了节省空间，我想将它们合并成一张大图表；类似于这里（也显示在图 B 中）。基本上，它应该是一张图表（xy 轴），结合了当前图表中的所有数据；但每个部分应该分开（可能通过垂直轴线）。我不知道该怎么做，可能吗？怎么做？
更多信息：我试图绘制的图表基于一个不太大的数据集。值 20、40、50、60、80 是百分点。图表中的当前条形图在 30%、70% 的值处有间隙，我不希望存在这个间隙。条形图可以像图 B 中显示的条形图一样接近。由于我有 10、20、30、40、50F 的数据（如表格名称所示），如果每个条形图子组在 xticks 下都有一个标签并按此顺序排列，那就太好了。除此之外，任何重新排列/添加都是可以的。 更新：是的，允许重新组织数据文件（无法在评论中发布）。

% 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
% - put all data in one file
