推荐答案

我认为您无法使用聚集的直方图样式执行此操作，因为gap选项仅接受整数.

I think you cannot do this with the clustered histogram style, because the gap option takes only integer numbers.

在只有两列的情况下，可以使用boxes绘图样式，将属于第一列的框向左移动框宽的一半，而将第二列的框向左移相同的量.右边:

In your case with only two columns, you can use the boxes plotting style and shift the boxes belonging to the first column by half of the boxwidth to the left, and the boxes of the second column by the same amount to the right:

set auto x
set yrange [0:100] 
set style fill solid border -1
boxwidth=0.45

set boxwidth 0.45 absolute
set style data boxes
plot 'test.data' using ($0-boxwidth/2):1, '' u ($0+boxwidth/2):2
