相对于x2轴在x1中绘制y1 [英] Plot y1 in x1 with respect to x2 axis

问题描述

我有一个数据如下:

y1   x1   x2
125  100   1
130  90    2
136  85    3
143  70    4
145  65    5

我希望将其绘制在gnuplot中，如图所示.

I would like to plot it in gnuplot as in the figure.

我使用了此处提到的步骤 Gnuplot:绘制x2轴相对于x1轴，但它以不同的方式绘制x2.

I used the procedure mentioned here Gnuplot: Plot x2 axis with respect to x1 axis , but it is plotting the x2 differently.

推荐答案

照常在x1和y1轴上绘制数据，但使用x2tic(3)在x2轴上放置其他标签:

Plot your data as usual on the x1 and y1 axes, but place additional labels on the x2-axis with x2tic(3):

set xrange [*:*] reverse
set x2tics
set xtics nomirror
plot 'file.dat' using 2:1:x2tic(3) with linespoints pt 7 notitle

如果您不希望使用常规数字，也可以同时使用x2tic和xtic:

If you don't want a conventional numerical, you could also use both x2tic and xtic:

plot 'file.dat' using 2:1:x2tic(3):xtic(2) with linespoints pt 7 notitle
