gnuplot：如何使用聚类堆叠直方图将总和放在条形图上方

Question

感谢问题及其答案，我学会了如何将堆叠直方图的总和添加到柱上方。但是，我无法弄清楚如何使用聚集的堆叠直方图来实现这一点。如下面的代码所示，我可以得到似乎放在正确 y 坐标上的总和。

不幸的是，我不知道如何更改第二个和第三个集群的 x 坐标，所以它们最终与第一个集群的总和标签重叠。我需要做什么来更改总和的 x 坐标，以便它们出现在正确的柱上？

我在这里尝试清理和简化您的脚本。我将数据作为数据块包含在内，因此只需复制和粘贴 & 运行。检查help sum，help columnheader...我希望剩下的是self-explaining。

脚本：

mySum(n) = sum [_i=2:7] column(_i)

plot newhistogram at 2, \
         for [i=2:7] $DataA u i:xtic(1) ti columnheader(i) lc i-1, \
         '' u ([=10=]+1):(total=mySum(0)):(sprintf('%d', total)) w labels offset 0,0.7, \
     newhistogram at 4,\
         for [i=2:7] $DataB u i:xtic(1) lc i-1, \
         '' u ([=10=]+4):(total=mySum(0)):(sprintf('%d', total)) w labels offset 0,0.7, \
     newhistogram at 7, \
